Bug ID: 403863
Summary: kwin crashed after resume from standby
Product: kwin
Version: 5.14.5
Platform: Debian stable
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
Application: kwin_x11 (5.14.5)
Qt Version: 5.11.3
Frameworks Version: 5.54.0
Operating System: Linux 4.19.0-2-amd64 x86_64
Distribution: Debian GNU/Linux buster/sid
-- Information about the crash:
- What I was doing when the application crashed:
resumed from suspend to RAM; normally at this point I get a pop-up "desktop
effects were restarted due to a graphics reset"; when it crashes I believe this
pop-up isn't shown but the crash notification instead
- Custom settings of the application:
I'm using the proprietary nVidia driver; currently version 390.87-6 but I
suspect this has happened with previous versions as well
The crash can be reproduced sometimes.
-- Backtrace:
Application: KWin (kwin_x11), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
