Description Patrick O'Callaghan 2021-04-28 16:11:50 UTC
SUMMARY
After configuring session-restore on login, then saving the session, many items are missing after starting a new session.

STEPS TO REPRODUCE
1. Enable "Manually saved session"
2. Set up some apps including Firefox, Konsole, Dolphin
3. Save the session using the Leave button

OBSERVED RESULT
On logging in again, neither Dolphin nor Konsole windows are restored. Firefox is restored.

EXPECTED RESULT
All saved windows should be restored.

macOS: 
Linux/KDE Plasma: Fedora 34
(available in About System)
KDE Plasma Version: 5.21.4

Or the devs you already have are interested only in next shiny thing than to fix bugs in their code...:-) Sure, we can't force devs to stick around forever and fix bugs in their code but sometimes, its good to stop new development and just fix the bugs. You will have more adoption and participation, and that can potentially get you more devs.

As a user, I also wish session restore to worked on Wayland, but inflammatory comments won't help expedite it.

I would like to know what's making this difficult. X11 had a session management protocol; does Wayland define something equivalent? If not, could Plasma do something limited to KDE apps?

Where is the current session save/restore code? Any documentation we could link in this bug to support someone who wants to give a shot at it?

I swear inflammation was not the intention. But truth can be hard sometimes and it lands wrongly in written communications. My apologies if it sounded like that.

It is true that devs like to move onto newer things. I see it everyday at work. And good teams and leaders have to bring them back to the table. We have burnt sprints doing just bug fixes solely because of this. And it works! The overall quality of the code improves and customers are happier and they spread the good word!
Comment 23 Ard van der Marel 2022-10-01 12:53:02 UTC
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.
Comment 25 imaginator 2022-10-02 13:34:48 UTC
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.

If it had been fixed, the status would have changed. 
With the "Importance" downgraded to "normal", I don't expect it to be fixed before Plasma 6.

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. ;)
Comment 32 Andreas Hartmann 2022-12-09 17:56:30 UTC
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:

Well I do like it, in fact I'm sticking with it, but I do miss being able
to restore the old session, for me it means not having to reopen dozen of
pdfs in different okular instances on different desktops

Same here. This bug is the only reason why I am not running Wayland. I usually have about a dozen PDF (okular) and over twenty text (kate) files open. It is too much work to open each of these files again every time I restart the computer.

Ever heard about sleep and hibernation? ;-)

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

If your windows don't change too much you can find a workaround on my dup: https://bugs.kde.org/show_bug.cgi?id=455900

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. ;)

I installed kubuntu 22.04LTS, that came with Wayland, how can I get back to
X11-Plasma, without returning to 18.04LTS ?

I think that's a question for the kbuntu support forum / mailing list.

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