Description Noy King 2013-01-24 14:27:19 UTC
PC-BSD 9.1 X64 version
Fresh install
Nvidia GTX 650 display card
i3 530 CPU
H55M motherboard

Reproducible: Always

Steps to Reproduce:
1. choose air-oxygen decoration. The current time, this bug doesn't happen.
2. restart kde
3. after login, the desktop appeared then freezes. Nothing can I do except the mouse cursor.
Comment 1 Martin Flöser 2013-01-24 14:34:59 UTC
* can you be absolutely sure that this is related to the window decoration?
* where did you get the air-oxygen decoration from?
* which version of KWin are you running?
Comment 2 Noy King 2013-01-24 15:00:48 UTC
Other decorations have not that bug.
I use PCBSD 9.1. I don't know how to get KWin version.
Comment 3 Noy King 2013-01-24 15:01:36 UTC
That OS uses KDE4.9.3
Comment 4 Martin Flöser 2013-01-24 15:06:44 UTC
what about other Aurorae themes? And once again: how did you get air-oxygen? This is very essential information as the one included in KDE SC is pretty much broken.

Please also provide the output of:
qdbus org.kde.kwin /KWin supportInformation
Comment 5 Noy King 2013-01-24 16:16:54 UTC
Other themes may be ok.

may be OK or are OK?

Could you please try disabling the translucency settings for decorations? 
Doesn't make sense for the problematic theme anyway as it provides a 
translucent background.
Comment 7 Thomas Lübking 2013-01-24 16:30:50 UTC
We first got to determine the meaning of "freeze".

Please cause the issue, then press "ctrl+alt+f1"
You'll be at a black login screen. Enter your username and password.

The type:
ps -A | grep -i kwin

There should be an output containg the kwin PID.
If not, the WM is simply not running (recursive crash) if so, please ensure to have "gdb" installed and run

gdb 2>&1 | tee kwin.debug

In the gdb prompt, enter

   attach <pid>

where "<pid>" is the PID next to the kwin process you obtained above.

That'll take a short moment. When done, enter

   bt

and press "enter" until there's no further output

then enter

   run

and wait a short moment, then press ctrl+c  - you should be at the gdb prompt again. Enter again

   bt

and enter until there's no more output.

Enter
   detach
   quit

you're back at VT1 from where you can

   exit

and ctrl+alt+f7 to return to the (still "frozen") GUI

If you need to login to another session, simply press ctrl+alt+backspace

Then share the output of ~/kwin.debug (attach it here)
Comment 8 Noy King 2013-01-26 09:02:27 UTC
Hi. I type bt, It always continues this:

Comment 10 Thomas Lübking 2013-01-26 10:27:25 UTC
The backtrace is not gonna change until you "continue" - my bad.
You get the display error because "run" will rewind the process, what fails because on VT1 you don't have DISPLAY=:0 exported.

The backtrace you presented is however from forking off a thread and waiting for I/O to be ready.

Since it only happens with the one theme, my remote guess is that
a) the theme is fundamentally broken (it's from 2010)
b) aurorae is not robust enough on this

(I recently encountered sth. similar when playing on the screenlocker QML. I had a typo, the QML was invalid and the greeter failed and restarted in a row)
Comment 11 Thomas Lübking 2013-01-26 15:29:31 UTC
The theme works here.
Please uninstall it, then ensure to remove if from the system

   rm -rf ~/.kde/share/apps/aurorae/themes/air-oxygen

Then re-install and try again.
Comment 12 Noy King 2013-01-27 04:16:33 UTC
There is no .kde folder at home folder
and no aurorae folder at ~/.kde4/share/apps folder
I found the theme is at here:
/usr/local/share/apps/kdm/themes/oxygen-air
and here:
/usr/local/share/apps/aurorae/themes/Air-Oxygen
Comment 13 Thomas Lübking 2013-01-27 07:19:08 UTC
.kde / .kde4 is distro specific (actually configurable) and kdm should be unrelated.

didn't you claim you got that theme via GHNS?
why is it in a global path then?
how *exactly* did you install it?
do you have sufficient read permissions there?

Decoration air-oxygen theme
Comment 15 Noy King 2013-01-27 09:00:23 UTC
I took experiment with build in air-oxygen theme.
Comment 16 Thomas Lübking 2013-01-27 09:25:34 UTC
There is no "built-in air-oxygen" and i don't want to see a screenshot of it either.

One more time: How did you install this decoration?

It's apparently not done via the  "get new decorations..." button (that will not write into /usr/local/share - and "air-oxygen" installs lowercase here)

Please either get rid of that deco installation and install it through that button again or try again with the backtrace (it is pointless to type "bt" 100 times in a row, once and once after "continue" , wait,  press "crtl+c" will do)


Otherwise there's absolutely nothing we can do since we cannot even figure what you installed there, not to mention what you mean by "freeze".
Comment 17 Joon Ro 2013-04-23 15:48:47 UTC
I actually have had this exact problem for a long time. It actually is not air-oxygen specific. It seems like whenever I use windows decorations with aurorae engine (so I have PluginLib=kwin3_aurorae in my kwinrc file), KDE freezes at login. I have installed decorations through Get New Decorations ... button. So far I have tried air-oxygen and Air-black with the same results.

If you have this, log in to console and just remove ~/.kde4/share/config/kwinrc. Then you should be able to login.

Can you still cause this (ie. when switching to an aurorae deco)?
In this case we can check what's going on there.
Also please attach the output of "qdbus org.kde.kwin /KWin supportInformation" (with settings that are used when this happens, but it's not necessary to use an arorae theme at that moment)

Thanks.

I will make it freeze, and then login through console and make the output then.

Unfortunately, when KDE is frozen at login, "$ qdbus org.kde.kwin /KWin supportInformation" hangs as well, even though I was logged in in a console (alt + ctrl + f1).

if you know what gdb is, this is more like a fortune =)

gdb --pid `pidof kwin` 2>&1 | tee kwin.gdb
(if you've no more pidof, because since systemd distros think that it's not usable for anything, "ps ax | grep kwin" and use that number as --pid parameter)

after gdb has loaded everything and you get a prompt, issue "bt" and press "enter" until there's no more output.
Then "detach" and "quit".
Attach "kwin.gdb" to the bug.

> even though I was logged in in a console
that doesn't matter, but the support output with a usable kwin (ie. back on non-aurorae theme) is just as good for this matter (the only different parameter will be the deco - and we know what that is ;-)

Just attached the output of qdbus org.kde.kwin /KWin supportInformation after I have deleted kwinrc. I haven't tried the gdb thing since I'm a bit busy at the moment - hope this is helpful.

I am pretty sure that I have. Even thought I'm using nouveau at the moment, I have used nvidia driver for more than a year. I must have tried this.

Sorry, I've got an important deadline coming up, so I might be able to try this next week.
Comment 26 razor 2013-05-16 13:00:13 UTC
Hello there. The similar issue troubled me for a long time. My system is gentoo x86_64 (with tesing branch, KDE v4.10.3 now).

Everything is fine with oxygen window decoration (use kwin3_oxygen plugin), and the KDE still works if I change the window decoration to such as FormaN (use kwin3_aurorae plugin) then, before the KDE is re-logged in.

But when I re-login (where the KDE startup with a window decoration using kwin3_aurorae plugin), the things becomes strange. The GUI will keep 'alive' if I don't open any window with title, or the GUI freezes. But the mouse cursor still be movable.

After an investigation, I found if the libqtextracomponentsplugin.so is loaded (when startup with oxygen then switch to aurorae) by kwin, the kwin3_aurorae will works. Otherwise, kwin3_aurorae does not (startup with aurorae, the libqtextracomponentsplugin.so will not be loaded by kwin).

I also tried the Arch linux and openSUSE, and all KDEs of them worked fine.

kde-base/kwin is emerged with USE opengl, kde-base/plasma-runtime has no special USE.

I'd claim that to be reverted logics, since if kwin hangs, the lib will not be dlopened.
Have you straced kwin on startup? Would you know how to do that and/or even betteer gdb into the hanging kwin from VT1 to see where it hangs around in this case?

      gdb --pid `pidof kwin` 2>&1 | tee kwin.gdb

Sorry, I should have done that.

The steps below I tried to do then:

1, login with FormaN (use kwin3_aurorae plugin)
2, run command: strace -o kwin.strace kwin --replace
3, open one window with title, and GUI hangs
4, switch to tty1, login root acc, pkill X
5, relogin KDE with my user acc
6, open one window has title, and GUI hangs again
7, switch to tty1, and launch: gdb --pid `pidof kwin` 2>&1 | tee kwin.gdb
8, use command bt to list call stacks of all kwin's threads

No need to excuse - if every user even *could* provide information at that level, debugging would be much simpler =)

"razormeister" does not sound too much asian, if you're not and have no need for XIM otherwise, move away /usr/lib64/qt4/plugins/inputmethods/libqimsw-multi.so
Since it seems what hangs (xcb waiting for events) to (probably) release your immediate pain.

You could also just run
    kwin --noxim
to deactivate it only for KWin.

Another test would be
   kwin --sync
to test for the impact of threading.

Unfortunately my experience with xim is ... limited.
Random guess:
What input devices do you you use? Mouse? Touchpad? Touchscreen?
Comment 30 razor 2013-05-17 10:46:04 UTC
I am asian :), and using fcitx.

So, then I move the libs (libqimsw-multi.so and qtim-fcitx.so) away from the directory, restart and relogin. The results are: GUI is alive, until I open a window with title, KDE hangs again.

After pkill X, I tried 'kwin --replace --noxim' and 'kwin --replace --sync' (w/e this option, shall I catch some logs?), and GUI freezes too, once any window has title is created.

Then, with the freshly restarting, I tried again w/e the combined both ways above, still bad luck.

My input devs are normal ps/2 mouse and AT keyboard.

Just guess, is it possible that the stuff not working is not kwin (or not only, IDK)? So, glad to learn more about how to check that. :)
Comment 31 Thomas Lübking 2013-05-17 10:54:53 UTC
The backtrace you posted ended in the xim plugin waiting for events.
So if it happens w/o xim it'll likely be rather that, randomly triggered by xim.

Please post the backtrace of hanging with --noxim so we can see where it hangs now, but it seems a race condition in X event processing (does the "freeze" also occur w/ compositing suspended?)
Comment 32 razor 2013-05-17 11:55:40 UTC
To make a SHORT story short. When I find the thread 1 of kwin still not returns in function poll<-??<-xcb_wait_for_event<-_XReadEvents<-XIfEvent<- ... <- _XimRegisterIMInstantiateCallback, even if I already move the libs away from plugins/inputmethods directory, and use 'kwin --noxim', I decide to uninstall fcitx.

After the fcitx is unmerged (and move libqimsw-multi.so back), everything is fine now. The theme such as FormaN will be loaded correctly.

So, I think the conclusion is reached (at least for my situation), just as you guessed before, there is a conflict between fcitx (IM) and kwin.

Many thanks for help. Very glad to find the problem. :D

Shift+Alt+F12, but that's atm. no longer relevant.
We need to figure why kwin conflicts with xim and in what way and who's fault it is.

Thanks for your efforts.

Comment 35 Martin Flöser 2013-05-17 12:15:04 UTC
If it waits in xcb_wait_for_event it can probably wait for an endless time. There should not be any xcb events being delivered to KWin. This looks to me like a pure issue by the XIM plugin.

So, any suggestion for me (a user need IM such as fcitx)? Anyway, I decide to try different versions first, then try different IM.
