Description Wian Potgieter 2020-01-14 05:59:03 UTC

Application: krunner (5.17.5)

Qt Version: 5.13.2
Frameworks Version: 5.66.0
Operating System: Linux 5.0.0-37-generic x86_64
Distribution: KDE neon User Edition 5.17

-- Information about the crash:
- What I was doing when the application crashed:
I had just resumed my PC with a 4K monitor (from 2x1080p).  I wanted to run nvidia-settings so that I could correct the configuration.
- Unusual behavior I noticed:
The 4k screen was not refreshing correctly but was getting input from the card.

The crash can be reproduced sometimes.

-- Backtrace:
Application: krunner (krunner), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

KRunner (5.18.1-0xneon+18.04+bionic+build58) crash log

This crash is still occurring when switching to a different display layout after resume on the latest available neon user repository.

Before suspend:
2x external FHD displays & 1 internal FHD display.

I need to confirm if krunner crashes before or after the manual display setup re-configuration.  
After:
1x internal FHD display & 1 External QHD display

Comment 4 Szőts Ákos 2020-05-08 14:51:44 UTC

Unfortunately, I cannot use DrKonqi to append to this bug (Bug 421187) therefore I have to manually paste a reduced stack trace here:

Application: krunner (5.18.4)

Qt Version: 5.14.1
Frameworks Version: 5.69.0
Operating System: Linux 5.6.6-1-default x86_64
Windowing system: X11
Distribution: openSUSE Tumbleweed

-- Information about the crash:
- What I was doing when the application crashed:

I pressed Alt+F2, started typing (without KRunner appearing) and KRunner has crashed.

@Wian Potgieter

1.

Does this issue still occur for you?

2.

When the crash occurs, what do you have to do to have a working KRunner again?
Just start KRunner again?
Reboot the computer?

3.

When the crash occurs again, could you immediately run this in Konsole:
    $ killall -9 krunner
    $ krunner
And check if the crash repeats?

If it does repeat, try this:
    $ killall -9 krunner
    $ QT_QUICK_BACKEND=software krunner
Does this fix the crash and allows KRunner to start properly?

4.

When the crash occurs, please run the attached gl-create.py Python script
and tell us what the output was:
    QOpenGLContext::create() == ???

Hi phd.
I have not recently had the crash occur.  It did reduce in frequency after I switched from NVidia to the Intel driver as well as from HDMI to DisplayPort cable.  Usually when I triggered KRunner via global shortcut after a crash, it would start again.

I'll keep the script handy for in case it happens again.

Thanks!

New crash information added by DrKonqi

krunner (5.20.5) using Qt 5.15.2

- Unusual behavior I noticed:

After I resume from a sleep, my dispaly setup changed 
- was: 4K + FHD (rotated to the left)
- to: mirrored mode

after login, I was pressing Alt+Space shortcut to run krunner, but it crash, and restart by it self
