Attachments: Back trace of plasmashell 5.5.3 freeze after resume
20160208: plasmashell back trace
20160208: Frozen kwin_x11 process back trace

Description Jürgen Scholz 2016-01-20 10:39:04 UTC 
I am using ubuntu 15.10/wily with the kubuntu backports PPA, which at the moment provides plasmashell 5.5.3.

Every time I resume my computer from suspend to RAM plasmashell freezes and does not react to any input. At the same time krunner is working fine and I can start applications or use already open ones normally.

The situation can be resolved by issuing killall plasmashell; plasmashell in krunner.

Additionally the mouse cursor is reacting with a lot of jitter to mouse movements, until a notification that eth0 has been re-connected appears. Sometimes there is a notification that eth0 has gone down (probably a delayed notification from the suspend process).

I created a back trace with gdb - I hope the information necessary to diagnose the problem is in there. If not, I am happy to provide additional details on request.



Reproducible: Always

Steps to Reproduce:
1. Start KDE session.
2. Suspend machine to RAM.
3. Resume machine.


Actual Results:  
Plasmashell does not react to input. Applications and krunner work.

Expected Results:  
Plasmashell does react to inputs. Applications and krunner work.

There is a similar bug report for version 5.4.0, which also showed this behavior on my machine. Please see https://bugs.kde.org/show_bug.cgi?id=352337

Back trace of plasmashell 5.5.3 freeze after resume
Comment 2 Jürgen Scholz 2016-02-04 16:13:40 UTC 
I am investigating the influence of redshift and and the Redshift Control plasma widget. It seems I can resume my system, when I use the plasmoid to turn redshift off before I suspend the system.
Comment 3 Jürgen Scholz 2016-02-08 12:02:30 UTC 
After further testing I found, that the presence of redshift does not change the behavior of plasmashell on resume (at least on my machine).

There seems to be a possibility to circumvent the crash I am experiencing:
1. Log in normally on boot (Terminal 7)
2. Use the session manager (krunner -> sessions) to create a second session for another user
3. Log in on second session (Terminal 8) and stay on that terminal
4. Suspend system
5. Resume system
6. Switch from Terminal 8 to Terminal 7 with the original session and find the screen locked and plasmashell not crashed.

20160208: plasmashell back trace

This is a more recent back trace of a frozen plasmashell process with most of the debugging symbols loaded.

20160208: Frozen kwin_x11 process back trace

This is the backtrace of the kwin_x11 process which handled the screen before the system was suspended. It used 100% CPU and killing it did not get plasmashell back on track. A new kwin_x11 process was spawned and handled the output correctly (applications working, plasmashell still frozen).
Comment 6 Thomas Lübking 2016-02-13 08:06:48 UTC 
Please do not compress backtraces.

Plasmashell is apparently in a deadlock between

Can you please open a new bug against kwin and attach the backtrace there?
It's totally unrelated to the plasmashell problem.
Comment 7 Jürgen Scholz 2016-02-16 14:54:08 UTC 
Thomas; thank you for your analysis. It is common to compress the logs for mesa bugs - here I will not do it again.

I opened a bug against kwin: https://bugs.kde.org/show_bug.cgi?id=359465
Comment 8 Thomas Lübking 2016-02-16 15:11:44 UTC 
This bug is not (necessarily) invalid. The problems in plasmashell and kwin are totally disjunct (though one may raise the odds for the other to occur)
Comment 9 sedrubal 2016-04-27 08:57:34 UTC 
Do you think, this ist related? In my case, plasmashell/kscreenlocker crashed after resume from suspending. After some time kscreenlock worked again but plasmashell crashed.
Additionally I have often the problem, that all GTK applications have rendering failures and drop some letters after resuming...

Application: plasmashell (5.5.5)

Qt Version: 5.6.0
Operating System: Linux 4.4.7-300.fc23.x86_64 x86_64
Distribution (Platform): Fedora RPMs

The crash can be reproduced sometimes.
