@Nate: is this going to be taken up any time soon? This is one of the biggest roadblocks to adopting plasma wayland for me. For example, its painful to rearrange firefox windows into different desktops after I start it. 

I have gone back to X11 solely because of this.

I don't know, sorry.

unfortuantely still an issue on plasma 5.24.90

Will this bug get fixed soon? It is the sole reason why I'm not on Wayland. Can someone let us know what time frame can be realistic expected for this to be sorted out? Thank you.

It's listed on https://community.kde.org/Plasma/Wayland_Showstoppers, so it will eventually get fixed/implemented.

This annoying issue is still present on Fedora 36 using KDE 5.97.0 with Wayland. 

Is somebody looking into this, or is there a timeline for when this will be fixed?

To be honest it stops me before using/testing Plasma session with Wayland.
IMO. This is one from the biggest advantage in KDE (recently even Windows 10 got it, at least for me.
I don't understand why this is so low on the priority list (issue reported over 1 year ago).

Would you like to contribute technical work towards fixing this issue? That's what there's not enough of right now.

I'm not sure if this is the question to me, because you didn't quote my statement only answered just after me. Assuming you asked me, I can reply only that maybe I would like, but technically this would be not feasible due to few free time (private reasons). Only from time to time I  can report some issue and this is enough what I can do, sorry.
Recently I use Neon unstable, so I think, I'm up to date with what's new in Plasma so in this way I test.
Sorry for my previous complains.

Hopefully this has contributed to answering your question: everyone with the technical ability to work on this issue is busy with other things that they have prioritized higher. :)

NOP for me. I work with X11, because here more things works better, or just work. Only, IMHO, KDE/Plasma a bit suffer because has less testers, because of this. And please don't understand me wrong, I would not like to set development priorities of KDE/Plasma.

In general, Plasma has enough testers and QA people. What it lacks is enough developers to fix all the issues those people find.

For me, with x11 applications running under x11 ad Wayland, it just seems to be a app startup mechanism. xcalc for example doesn't remain state after logging out. The observed result has been found because Firefox has a option to reopen the pages that were closed during the shutdown of Firefox. Therefore i think changing restore to reopen would be more accurate and a more concrete path to a solution.

after the user ends session by logging out, rebooting, etc. Before closing the applications, the paths of the open applications should be saved to a (session) file from where these can be opened.

I would be interested to know how the x11 application reopen is done in Wayland as hopefully some of the solution can be reused or be expanded on to include Wayland applications. Im not completely confident in my c++ skills yet as im studying it, so maybe some would like to help me tackle by introducing me to the project structure and the working parts making up KDE.

Your comment was not inflammatory at all. It was your opinion expressed in a friendly and factual manner. IMO.

But it seems to me that esp. in the FOSS community quite a few people simply can't stand critigue, however constructive or well intentioned or politely formulated it may be. They seem to experience critigue as an aggression and not as a chance for improvement. And I consider that a major weakness and an obstacle to success.

This "bug" or missing key feature, as I see it, is obviously really bad and at this point of time quite shocking. Two days ago I was about switching to Plasma-Wayland because I had such a favorable impression of it. Until I discovered this thing.

I don't know whether this situation is due to a lack of provision in the Wayland-design or an inability of developers to focus on what really matters. But if the Plasma devs could solve this on their own, I'd strongly suggest they drop any other Wayland related work *NOW* and start working like hell on resolving this issue.

Because this is so detrimental to Plasma's and KDE's reputation that they may not recover from it. IMO.

Same problem here with leap 15.4. Would be really nice to get it fixed ... .

Hi all, 

same problem here does anyone know if the bug has been fixed?

ok, thanks for the clarification, I will be moving back to Xubuntu 20.04 LTS, since I make big use of this feature

I'd say that 99 % of the users make use of this feature. The rest either don't know that it exists or never log out because they are incurably addicted to Plasma-Wayland. ;)

I don't think there are so many Wayland users out there because Wayland has so many restrictions and bugs so far (and I don't see any solution).

Andreas, I would respectfully disagree.  I switched to wayland once multi
monitor support started working and have not looked back.  Here, at least,
the color is more vivid using wayland (eg X looks washed out).  Aside from
a few irritating bugs like this one, it works well.

Just as a reference point, Wayland session usage is shown gradually growing here:

Sure. I use them daily. I'm on Arch Linux which is not shy in updates. Several updates (kernel (zen), etc.) require a reboot.

In my view, the most obvious and promising "workaround" for an ordinary user is to continue enjoying Plasma-X11 until all major issues in Plasma-Wayland are fixed and it's ready for productive use. ;)

That's what I do as well, but it's not really what I would call a workaround.

Exactly same problem can be seen even if KDE is run in wayland mode ... .

Please ignore my last entry - wrong ticket :-).

I've been "forced" to move now to wayland to get the per screen scale factor as it will never be implemented on X11. But loosing restore session is a pain.
It seems we miss a global review on plasma development, with clear objectives for each release, to make all users (and developers) happy.

I'm sure it holds the top position on their priority list for Plasma 6. 
But: who knows? ;)

Looks like some work was started 3 months ago and then, it stopped.

I tried to use wayland again to see if the experience is any better and went back to x11 after an hour of frustration. I have 4 different desktops for various projects and just restoring all my konsole windows (about 9 of them) and their tabs, and placing them in their respective places on each boot is a big pain. Let's not even talk about putting other apps where I am used to seeing them. 

How does a serious dev use wayland at all? I am just curious.

My thoughts exactly. I've no doubt that serious devs *do* use Wayland, but I've no idea what their workflow is like. For me, session restore is an absolute requirement, so I keep feeling I must be missing something.

Session restore is such a basic feature nowadays that it seems crazy to even have to waste one thought on it.  It *has* to be there.  Like wheels on a car.  If not, something went seriously wrong somewhere.

My way to deal with that - IMO disappointing - Wayland-show is that I simply don't care any more.  To me it doesn't offer any benefit.  And as long as there's a Plasma-X11 I'm happy.

Still an issue on Kubuntu 22.04, going to switch back to X until it is fixed.

Will what is planned for KDE 6 take into account multiple monitors and multiple virtual desktops so that apps start in the desired monitor/virtual desktop?

That is crucial!

And please don't forget about activities!
I'm tired of moving Firefox windows to different activities manually each time after login even on KDE 5 X11 session.

Yes my experience proove it, I usually have 10 tabs opened in konsole, most of them are dedicated to a relative work, and as such the directory in which the last session was run, and is restored on the right desktop.
That IS the most reason I don't use (yet) Wayland.

the same here.

Does that plan also apply to Plasma-6-X11 or will session restore there just keep working like in Plasma-5-X11?  Thanks.

How about using this piece of software?

https://github.com/Vladimir-csp/uwsm

Session is restored in strange way. Firstly starts applications, so we have black screen and starting apps. and at end starts plasmashell.
Second thing is that session in konsole is not restored, but in IceWm its working well.

Applications also start in front of a black screen for me as well in 5.27 on X (and have in 5.24 as well).

>How about using this piece of software?

That's not what's missing, that's a replacement for what we call "startkde"

This is marked RESOLVED as FIXED for a while now.

Do people have experience with the new session restore in Plasma 6? How good is it working with X11 and wayland?

No signs of session restore as of 6.0.90

Could be related, could be not but I am "loosing" configurations set in system settings since a couple of versions. Not sure when this starts to happen but sure after the release of the first "stable" version. For example, I am lousing manual file association that I have configured, the landing page of system settings is no longer showing me the last used configurations pages and the restored session is not working. These are the ones I have noticed. But the theme is correctly saved and restored, for example. Could be that these configs are stored in places that gentoo eats or has set the wrong permissions? Any log file I could check for this kind of errors? 

The key point is that I have recently switched to wayland. The FIRST log in, these things were working (so I have correct file associations, a correct restored session and the used last used config pages) but as soon as I reboot / log off (not sure what was the action), I lost all of them. In any case, the problem with file association and landing page of system settings is also happening on xorg (but not the restored session, that is working fine on xorg). 

Should I file a different bug report or do you think it could be the same problem? Should I fill this in gentoo bugtracker or here?

Please file a separate bug report. I don't think this is related.

(By the way, the word you're looking for is "losing", not "loosing". Two different things. No offence but this is a common mistake).

Please file a separate bug report. I don't think this is related.

(By the way, the word you're looking for is "losing", not "loosing". Two different things. No offence but this is a common mistake).(In reply to devsk from comment #99)

Not as yet on Fedora 40, Plasma 6.0.5. I think 6.1 is expected soon and hopefully Fake Session Restore will be part of it.

here I have Kubuntu 20.04 and plasmashell 5.18.8 works (almost) perfectly:

- it reopens okular, konsoles, kate, thunderbird and multiple firefoxes 
in the same Desktops, same location, on the same files or webpage

- it reopens Tekstudio in the wrong desktop with the same files open

- it reopens gvim and Paraview with no file open


I'm stuck with Kubuntu 20.04 because I just need this feature

"If things don't come easy, there is no premium on effort." (Branch Rickey).  So why don't you just dump Plasma-Wayland and use Plasma-X11 until this essential (but nowadays rather trivial) feature is _fully_ implemented?  At least from a productivity point of view a masochistic adherence to Wayland doesn't make sense.

What's mentioned there as "rudimentary support" for 6.1 seems to be what's described in comment 84.  For me that wouldn't be enough.

You're not stuck there. Session restore (still) works on the X11 session on Plasma 5.24 (Kubuntu 22.04) and Plasma 5.27 (Kubuntu 24.04).

thanks, I will give it a try

So, after reading the comments, it looks like it is still the "same old same old". Sticking with plasma 5 then!

Just a heads-up to note that Plasma 6.1 is now available. I have installed it on Fedora 40 (via the normal dnf upgrade system) and look forward to testing it.

> Switched back to "On last logout" and it is still working. Very pleased! Thanks to everyone who put in the hard work to make this happen for Plasma 6.

What you are saying is that switching away and the switching back to this option made the session restore work properly for you with 6.1. 

Can you please confirm what all works? Does it put all your console windows with their tabs in their respective desktops? How about firefox windows? 

What else did you try to restore?

restoring okular is also important for me

That's in line with comment 84.  So still no proper session-restore for Plasma-Wayland.  Clearly, this bug is not yet fixed and therefore should not be labelled as such.  

And to make Wayland the default for Plasma 6 with such a deficiency was a rather questionable decision which borders on self-sabotage, IMO.

Plasma under X11 didn't do those things correctly for me either, except possibly the tabs in Konsole. I'm not sure because I always used Autostart, which I'm intentionally not doing now, so behaviour maybe be different.

If session-restore also doesn't work in Plasma-6-X11 (it's always been working flawlessly for me in Plasma-5-X11) the situation would be even worse as there would be no correctly functioning alternative.  For the sake of Plasma and KDE I hope that this is not the case.

To give you an impression: among other things and apart from quite a few tabs in Dolphin and several instances of Konsole, Okular and Gwenview, I currently have over 20 docs open in Kate.  That's not unusual for me.  And would I want to re-open all that stuff _manually_ each time I have updated the kernel, for instance?  In the year 2024!?  I wouldn't even dream of it!

Fedora 40, KDE Plasma 6.1.0. When I login on a Wayland with my own account, I am greeted by a heap of 18 konsole and firefox windows, all stacked up on the first of my eight virtual desktops. I am the designated one to distribute and reposition them again, until next reboot. It's unusable like this. I can't use my own account under wayland, not even just for testing. 

The current state only really 'works' for one use case: you only have one desktop and all your windows are maximised. Granted, that's how most MS Windows users I know use their computer, so maybe it fills many people's needs. But it's not up to par with what a long time plasma/x11 user expects. 

Session management is very much _not_ fixed and because of this, plasma/wayland is still not ready for prime time in my workflow.

Is there more work planned for plasma 6.2 to address the issues with session restore (via another bug)?

or do we need to reopen this bug and address the remaining issues via this bug?

Well, with modern laptops featuring extremely high resolution displays, and a multiscreen setup, X11 simply cannot handle such setups any more.

With Wayland, a bunch of X11-features that have been "sort of working" like X-forwarding, screen sharing (in Teams/Zoom), and session management stopped working, but a whole lot of pain points that I had to work through over the past two decades went away, such as the resolution issue mentioned above. Ever since I adopted Wayland, screen sharing has been fixed and X-forwarding can be replaced by alternatives like VNC, which leaves session management as the last big ticket item.

Regarding the fake session report, Fedora 40 has backported the patches to Plasma 6.0 a few months ago, so there was not really any change with the update to Plasma 6.1. I otherwise came to realise that the fake session restore is working exactly as advertised (cf. https://bugs.kde.org/show_bug.cgi?id=436318#c84 or the commit message at https://invent.kde.org/plasma/plasma-workspace/-/commit/660988b0e30ee8ccac98c0cf164b142d70709675).

So, got to wait until somebody with the necessary knowledge and skills implements true session management in KDE Plasma.

I am also in the camp that windows not remembering which desktops were in is a dealbreaker for me. I sometimes use multiple desktops in my workflow and this feature may be more tedious to deal with than having session restore disabled. I'd rather have the feature disabled and start over from each reboot than have to sort through lots of windows to their right desktops.

I defined some shortcuts (Ctrl-<N> for "send window to desktop N") but it's still tedious to have to do it for every login.

In this respect perhaps "Failand" might be a more suitable name.  Anyway - in comment 25 I already pointed to the possibility of Wayland being the root-problem.  And I guess that KDE has been aware of it since long (comment 62).  But instead of using their clout as a leading Linux-DE and publicly pointing out and criticizing a glaring Wayland-deficiency they even chose Wayland as default for Plasma 6.  IMO, this was a major strategic error as it not only leaves Plasma-6-users with a bad and obviously hard to fix regression but also lifted the pressure off the Wayland-devs to finally (!) provide a basic feature of modern DEs.  

Now it seems that Plasma-6-users are at the mercy of the Wayland-devs (comment 89).

Taking the initiative and going ahead may indeed be the right move.  Certainly better than wasting more time by waiting and hoping for a long overdue protocol to get approved (or not) at an unspecified point in time.

Why was this bug marked resolved/fixed? It's still an issue under Wayland in plasma 6.1.1. Manually saving a session does not save all windows/apps and the ones that do reopen on the wrong desktops.

Simply putting the onus on wayland to "hopefully" fix it is not a solution.

Maybe we should change the severity of this bug to CRITICAL.

Gentoo sort of forced me to update to latest plasma by deprecating some of the packages because of dependency hell. 

And now, the X11 session restore is broken....:-(

Not sure about Gentoo, but for Fedora, there is no X11, Wayland is the default. X11 only apps are handled by a bridge. Even before this the Wayland session restore was broken. The X11 session restore was broken but was fixed some time ago. 

With Wayland some applications are not restored at all and onlers are all restored to the first virtual desktop. Had I known the session restore was not fixed in wayland I never would have upgraded to Fedora 40 from 39

(In reply to Brian Kaye from comment #142)
The X11 package still exists for Fedora - see https://www.reddit.com/r/Fedora/comments/1cbgria/comment/l1dor96/?utm_source=share&utm_medium=web3x&utm_name=web3xcss&utm_term=1&utm_content=share_button - it's merely not included by default.

That's Fedora's own initiative. Fedora's mission is to "lead the charge" on innovations even if it breaks some people's workflows. Plasma 6 still supports X11 session and there are more conservative distros that aim to support X11 (IDK if they upgraded to Plasma 6 yet though).

openSUSE Tumbleweed has upgraded to Plasma 6, yet retained its XOrg 11 session.

IIRC this was discussed on the Fedora KDE mailing list (by me and others) before F40 was released. I hate it but I go along with it because the alternative is to eventually fall out of support shortly after F41 comes out. I currently have shortcuts to move my (many) open windows to the right desktops. My main issue is with Dolphin not remembering the state of each of its open windows, but I suspect session restore on its own isn't going to fix that. See https://bugs.kde.org/show_bug.cgi?id=455324

Indeed, this is the last thing keeping me from using Wayland!
I'd be happy with dolphin restoring for the beginning.

Dolphin doesn't restore properly on X11 either.

I'm also having this problem in the X11-session of Plasma-5.27.11 (with security-update plasma-workspace-5.27.11.1).  The symptoms are the same as described several times already.  Just KDE-apps are restored but only in their native state, that is without previously opened documents etc.

Now even the the latest version of Plasma 5 is completely unusable.  What a dire story.

Currently, having the following configuration, Dolphin restores good enough, meaning it loses only its windows positions, but keeps all the opened paths, split views etc..

AFAIK this wouldn't solve the "multiple Dolphin windows" problem. To summarise:

I have 3 Dolphin windows, all on the same desktop. Window A has two panes, each in a different directory. Window B also has two panes, each in a different directory. Window C has a single pane but an open terminal and is in yet another directory.

On session restore, all three windows are identical copies of *one* of A, B or C. Which one it happens to be is essentially random, though it might be the one that happened to be on top last time.

When I first reported this over two years ago I was using X11. AFAIK the bug has received no attention in the interim.

(This should really be discussed on the other report already linked above).

"Thunar" keeps the settings after (Plasma-) session-restore, just checked your use case.  It doesn't have an integrated terminal, though.

I just tried it, but no. After saving the session and re-logging in, Thunar is not restored and when I start it manually it doesn't recover the saved sessions. I haven't tried it with Auto-start. I note that it does have an "open terminal here" option (which currently fails because of some setting). I presume it doesn't open a new pane in the same window, though that wouldn't be critical.

Sorry.  Perhaps we are using different Plasma-versions.  I reverted to -5.27.11 where session-restore does work for X11 (it does _not_ in -5.27.11.1).  And here Thunar-4.18.6 behaves as described.

Actually Thunar does offer split windows.  And for the one window where you need the integrated terminal you could use Dolphin.
Good luck!

Yes, I know Thunar has horizontally split panes. I meant that a terminal wouldn't open in a  new horizontal pane in the same window, as with Dolphin. However this is a minor point.

Hi, I've just tried this on Plasma 6.2 Dev on KDE Neon.
The build was done from scratch issuing kde-builder --refresh-build workspace --ignore-modules sddm-kcm (SDDM KCM module fails at build but it's not essential here).

I've got the following behavior:
- left a Dolphin open at logoff/shutdown
- logged in back with a Wayland session
- Dolphin opened at login, but maximized on the screen
- left a Dolphin open at logoff/shutdown once more
- logged in back
- no Dolphin anymore

so is it fixed now? If I install kubuntu 24.04, and the necessary 
updates, will I have full session restore ?

If Kubuntu 24.04 ships Plasma 6.2.0, then yes, unless the change that fixed this didn't actually work.

what distro should I install to get session restore working? or can I 
install Plasma 6.2.0 on top of Kubuntu 24.04 ?

There are over 100 people CCd on this bug report, and every comment sends all of them an email. So I would recommend taking installation and versioning questions like those elsewhere — for example to https://discuss.kde.org. Thanks a lot!

IMHO the bug is definitely not Resolved. Save/Restore session continues to be an unimplemented feature. I appreciate Nate's efforts with regard to "fake session restore" but it is a stopgap, not a genuine solution.

Well, you reported this bug.  And if you think that it is still not resolved then re-open it.  I'm pretty sure that the vast majority of people on the cc-list would support and appreciate that move.

However, it would be better if the assignee(s) reopened it.  Doing so would be the most sensible thing anyway for anyone who has understood what this bug-report is about.  It would also display some respect for their users and that they are not trying to lead them down the garden path.

Done. I also edited the title to make it clear that it covers Resume as well as Save.

Session restore still not fixed with plasma 6.2 rpms on Fedora FC40.

Still not fixed with plasma 6.2.3-1 rpms on Fedora 31. Sessions still restored to first virtual desktop. A pain but they are at least restored somewhere.

That's something else: Bug 482816.

Typo. Shoul refer to Fedora 31 rpms

Should be Fedora 41 RPMS. I am a lousy typer :-). Would be nice to edit a comment.

I surely hope so.  I'm sure I'm not the only one who finds it extremely annoying to have to reposition my windows each time I log in or reboot my system.  In fact, I update my system only once a month (dnf upgrade) because I'm tired of having to resize and reposition my windows each time.  

SunOS OpenLook did this beautifully, accurately, and reliably way back in 1990.  I've tried 4 Linux distros, and this does not work on any of the ones I've tried.  Why is it that Linux has so much trouble with basic things like this?  Who does the prioritization of work on Linux platforms?  Do they get the feedback from users?

> Is this ever going to be worked on by KDE?

In my mind, there are two answers to this question, and both are correct answers:

1. We have no plan to get this working on KDE anytime soon
2. We have a plan and here is the schedule (gnome guys took this approach)

I haven't seen 2) for KDE anywhere on the interwebs. Can we at least create a plan? Its fine if its done in 6 months from now or 1 year. But let's have a plan and work toward it.

1) is also fine but then, let's state that clearly so that we can stop coming back to this bug (its almost 4 years old now) every few months.

To me, it almost feels like, because this bug is open, someone is working on it in the background when, in reality, no one is, and there is no way of knowing if someone is or not.

PS: I found the following for kwin but its 2 years old and open: https://invent.kde.org/plasma/kwin/-/merge_requests/3024

There is a work-round if you use sddm: select X11 on the login screen, rather than Wayland, and you'll have the proper restoration of desktops and their windows. It works for me, anyway.

Regarding session-restore, Plasma-X11 works for anybody. ;)  
The question is whether your distribution offers it, as Plasma-wayland unfortunately is the default now.

To me the central problem in this affair seems to be the obviously still missing wayland-protocol (see Comment 89).

It doesn't matter whether your display manager is sddm, lightdm, gdm or whatever.  If the distribution supports Plasma-X11 in addition to Plasma-Wayland, you can choose between them when logging in.

A Linux-system is a huge mosaic of several hundreds or more pieces of software provided by probably as many individual projects (communities of developers).  There is no central authority that can set/enforce priorities or order certain devs to get out of slo-mo mode and finally provide what others urgently need.  

By making Wayland the default for Plasma-6 instead of sticking with X11 (and publicly explaining why), KDE unfortunately gave away the only leverage they had in this affair.

openSUSE Leap 16.x still uses X11 / KDE 5 as default as far as I know or better as I'm using it.

You probably mean 15.x?  AFAIK they do not even offer Wayland for those versions.  But anyway, we're talking about Plasma-6 here, not Plasma-5.  
KDE chose Wayland as default for Plasma-6.  So if a distribution only offers the default Plasma-6, then  the user has no choice - and no session-restore.

Updated the Restore script to handle window titles with special characters.

Have you ever put the script that restores the windows into "Autostart" as well?  I don't know whether one has any influence on the sequence in which the programs are started but _if_ they are started in alphabetical order you could name it something like z_script.

More on topic: the funny and real mean thing with session-save/-restore in Plasma-wayland (-5.27.11.1) is that _restoring_ a previous session does work fine (perhaps apart from minor differences in window-positions).  I can tell because when I log out of a Plasma-X11 session and then log in to a Plasma-wayland session, the previous (Plasma-X11) session is restored almost perfectly, incl. kate, dolphin, whatever.  And that's reproducible.  However, if one then logs out of the Plasma-wayland session and in to a Plasma-X11 session (or Plasma-wayland session), the previous session is gone, except for non-KDE-apps like Firefox or Thunderbird.

So, from what I see here with Plasma-wayland, the real problem is not _restoring_ a session but _saving_ it correctly.  And what makes matters worse (somehow) is that the state of non-KDE-apps like Firefox/Thunderbird _is_ saved correctly in ksmserverrc [1].  What's not saved is the state of KDE-apps.  But perhaps you know all this already. ;)

It doesn't work (I tried it). AFAIK Plasma fires all the Autostart scripts concurrently and I don't see a way to make the Restore script wait until everything else is up, or at least has mapped its window(s). Maybe there's some systemd magic that would do it.

You could use "sleep" (-> sleep --help) to delay the execution of the relevant parts of your script until other scripts have run or the desktop is fired up.  Example:

#!/bin/bash

# Test "sleep".
sleep 10
echo "This was a test."


HTH.

On older systems, this wouldn't really work, since there's always something that randomly takes ages to launch. Is there a way to wait for a specific process to be invoked? If so, perhaps wait for `plasmashell` to be running, then run the script, since it's usually one of the last things to run. https://stackoverflow.com/a/9118509/9731176 might be of use.

I generally think timer-based solutions are inferior to triggers, but you can do that if want. It strikes me as even more kludgey than what I already have, and given that the user has to manually save the session anyway it wouldn't even have the advantage of transparency.

Behaviour may have changed. Not sure of when this happened but I just noticed that the session restore does not resume windows to the first virtual desktop. It restores the windows to the last virtual desktop that was used in the previous session. I little window is flashed that says the name of the virtual desktop and then proceeds to restore the windows in that desktop.

I finally moved to wayland with 6.3. I had to jump through some hoops though. Here is the code in case someone wants to try the save/restore scripts (make sure to read the comments on the gist before using this code):

I simply went with the option of starting all the applications from the saved session and then giving user a dialog box to OK the moving of the windows to their respective desktops, positioning them at the saved location and resizing them as per the saved info.

The user just waits for all the application windows to start in the current desktop and then, pressing OK does the work. There are tricks to center the dialog box, keep it above all windows and activating it. kdotool works really well to do the rest.

Checkout the gist I posted. Most of code can be used as is. Only binary names need adjusting/addition/deletion.

What does kwin-fix_crazy_gesture.patch do? Seems to be a patch to the kwin source code.

On all platforms where I have used the swipe gesture, it takes to the right desktop when you swipe left. With X11, it was like that (imagine years of motor tuning). With wayland, it drove me crazy because every time I wanted to go a desktop, it took me to the wrong desktop.

This behavior would be typically changeable but everything I tried using touchegg, confused the desktop navigation more: touchegg would move it to next but kwin would move it back, meaning that it did not change the desktop. After some real desperation, I took the drastic step of finding and toggling the gesture in code.

So this patch has actually nothing to do with session restore. I'd suggest posting it somewhere else to avoid confusion.

I've had a quick look at your scripts but haven't tried them. They seem quite complicated, but maybe they do more than mine. I've taken note of how you use 'kdotool windowmove' and have added this to my own scripts (don't know why I hadn't noticed this before :-). I'll upload them shortly (still not very familiar with Gist to be honest).

Updated again to save/restore window positions.

Yes. I don't think anybody cares about flipping the gestures behavior. I will keep this patch around.

Yes. My script does do way more..:-) It saves a lot more information in a format which is easily read in bash. Then, it starts all the apps and waits for the user to ack the restoration process which restores their desktop, position and size.

I had to add a lot of code for robustness e.g. some random processes make their way into 'kdotool search' when they don't have a real window associated with them e.g. plasmashell. 

For example, restoring from X11 to wayland, the window class changes from konsole to org.kde.konsole.

For example, the size and location on wayland are floating point numbers sometimes, which was not apparent until wayland locked up on creating a window with 0 size with infinite memory allocation loop and got killed by OOM.

For example, if you saved session from a crontab periodically, kdotool just doesn't find any windows because crontab does not have access to the user environment to access the DBUS.

Lots of accounting for quirks.

I'd suggest keeping it separate from the rest. It's confusing to have it lumped in with the save/restore stuff.

All the apps I've used already remember their sizes on restarting, so I don't bother with that.

I'll consider using Zenity or similar, but given that it only helps with restoring and not saving, I wouldn't place a high priority on it. If there were a reliable way to save state on logging out, that would change. Unfortunately the Auto-start logout scripts only seem to trigger once all windows have been destroyed.

I already skip plasmashell, and if anything else has this behaviour it would be trivial to add.

I don't care about X11. I wrote this specifically for Wayland.

kdotool can return floating-point values for position, but doesn't accept them when trying to set it. This to me is a bug. However I'm not worried about fractions of a pixel, so I just truncate these to integers.

Not something I do. I only save the state explicitly.

> All the apps I've used already remember their sizes on restarting, so I don't bother with that.

konsole doesn't do that for me. It opens a single window of a dimension from the profile.

My script opens as many konsole windows as you had open before, moves to the right location in the right desktop and sizes them.

Thanks for pointing that out I almost never have more than one Konsole terminal open so hadn't noticed. It does however remember the size of the single one it opens.

That can only happen if someone was working on it. Nobody is. The presence of this bug gives that wrong impression.

I gave up on this bug ever getting fixed. That's why I ended up writing the set of elaborate shell functions I wrote. They do most of the work for session restore for me and I have been super happy with that. It works better than both the x11 and wayland restore in KDE right now.

I posted something that gets me 95% of the way there. If KDE had gotten me there 1/2/3/4 years ago, I would have moved to wayland much earlier and never complained.

> People are working on this. 

Why so secret about it if people are working on it? We rarely see any updates here or anywhere else I could find with google search. What I could find showed that the development stopped more than 2 years ago.

Can you please point to the discussion thread for this? I need read-only access and have no (or had any) intention of spamming anyone. The last thing I want to do is to annoy the people who are working voluntarily on this feature.

You don't seem to realize the gravity of the situation.  The sheer number of people on cc should give you an idea.  But I guarantee you that this is only the tip of the iceberg.  

This bug is critical and several years old already.  It's a real strain on users' nerves.  There's no noticeable progress.  And other than this thread practically no information.  No wonder patience is coming to an end.  

Thus, instead of brushing off legitimate requests for information as *spamming* and expecting users to just shut up, sit still and wait in awe for comments from the Bug Janitor Service, I suggest you either significantly increase your efforts to find a solution for this or at least re-evaluate your communication policy and your attitude towards yet loyal users.  If you don't want to go under, that is.  Thanks.

Who's "whining" here?  Most are just seeking information that is hard to find elsewhere.  Some opposed attempts to prematurely close this bug.  Others contributed (partial) workarounds.  I can't see anything wrong in that.  Indeed, I found that more instructive and constructive than the sound of silence from the "officials".

Again, I don't like your deprecating wording and I find it completely unfitting.  Contributions to deal with this mess have been made, by me and others and if you can't rate that as "something added", so be it.  But one cannot expect the users here to solve a bug that so far has been unsolvable for the experts.  And BTW: what have _you_ added to solve this?

I consider my reply to your post indeed a contribution as it hopefully brought it home to the KDE-guys that this is a _huge_ problem and that they urgently need to do something about it or at least improve their communication.  Just hushing this up is not going to work much longer.

But if you don't like being bothered by "whinings" or "grievances" like that, simply take yourself off the cc-list.

David Edmundson is it resolved? What Plasma version? How to test? Is it the same session restore like in X11, or better, or some fake restore? Could You explain please? Thanks!

What does a "Status: Closed Later" mean?

Maybe the resolution description is too broad. Perhaps if the problem is broken down into smaller pieces some of he users would be satisfied withe some of the steps toward the final objective. For me the first piece would be to restore the windows to the proper desktop(s). I realize there are subsets to the solution like same window on multiple desktops, of multiple instances of the application in the same window. But first define the end objective and prioritize the steps to get there. 

As a part of this does anyone know what is the format of the session save file? To restore you first have to save the current information correctly.

> David Edmundson is it resolved?
> What does a "Status: Closed Later" mean?

Now that you guys have pissed off the main developer, whatever implementation was coming in the spring is now off the table.

just kidding....:-) Nothing was coming this spring.

All David had to do was to remove himself from the CC list and he would be fine. But he had to use his developer hammer. The patience and the kindness comes difficult these days!

In the meantime, I made a change to my code snippet to match the title with regex because I realized that if the title of the window had some information that was variable (e.g. a tab in firefox has yahoo mail and N unread messages, and next moment it is N+10), it won't restore it correctly. In case you want a poor man's session restore:
