Bug ID: 375624
Summary: Kwin crashed after resuming the display from power
saving
Product: kwin
Version: 5.7.5
Platform: Ubuntu Packages
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: kwin-bugs-n...@kde.org
Reporter: andy...@mail.ru
Target Milestone: ---
Application: kwin_x11 (5.7.5)
Qt Version: 5.6.1
Frameworks Version: 5.26.0
Operating System: Linux 4.9.0-5.1-liquorix-amd64 x86_64
Distribution: Ubuntu 16.10
-- Information about the crash:
- What I was doing when the application crashed:
I left the PC inactive for some time so that the display turned off for power
saving (the PC itself was still running, no suspend mode or anything). Then I
moved the mouse and the display turned on showing that kwin has crashed.
Kubuntu 16.10 x86_64, Nvidia drivers 378.09, kwin 5.7.5.
-- Backtrace:
Application: KWin (kwin_x11), signal: Segmentation fault
