Bug ID: 372783
Summary: KWin crashes
Product: kwin
Version: 5.8.3
Platform: Archlinux Packages
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: kwin-bugs-n...@kde.org
Reporter: ablepha...@gmail.com
Target Milestone: ---
Application: kwin_x11 (5.8.3)
Qt Version: 5.7.0
Frameworks Version: 5.28.0
Operating System: Linux 4.8.8-2-ARCH x86_64
Distribution (Platform): Archlinux Packages
-- Information about the crash:
typical actions before/while crashing:
- Switching windows
- Returning from lockscreen
I seem to experience the same problem with open drivers, resulting in problems
like:
https://bugs.freedesktop.org/show_bug.cgi?id=98138
https://www.kubuntuforums.net/showthread.php?70430-nouveau-SCHED_ERROR-blocks-keyboard
and forcing me to reboot.
nvidia drivers seem to be able to recover, by switching to tty console, at
which point i will get switched back to graphical session. From then on, kwin
crashes almost every time that I try to switch windows via Alt-Tab. I tried
different Visualizations (Small Icons, Text Only), with no change. Deactivating
it (but still showing selected window) works.
The crash can be reproduced sometimes.
-- Backtrace:
Application: KWin (kwin_x11), signal: Segmentation fault
