Bug ID: 377845
Summary: kwin craches at resume from standby
Product: kwin
Version: unspecified
Platform: Kubuntu Packages
OS: Linux
Status: UNCONFIRMED
Severity: crash
Priority: NOR
Component: general
Assignee: kwin-bugs-n...@kde.org
Reporter: guit...@hotmail.de
Target Milestone: ---
Application: kwin_x11 (5.7.5)
Qt Version: 5.6.1
Frameworks Version: 5.26.0
Operating System: Linux 4.8.0-34-generic x86_64
Distribution: Ubuntu 16.10
-- Information about the crash:
- What I was doing when the application crashed:
I pressed a key on my keyboard to get my system resumed from standby.
I am also wondering, why bugs.kde.org tells me 5.8.4 is the oldest supported
version, while my up to date kubuntu 16.10 has kwin 5.7.5 installed - this
sound wrong for me.
- Unusual behavior I noticed:
The screen was off for tty7 (off - not black color displayed), a switch to tty1
and switch back to tty7 appears to restart kwin. And I was able to logon again.
No session state seems to be lost (all programms were stil opened).
The crash can be reproduced sometimes.
-- Backtrace:
Application: KWin (kwin_x11), signal: Segmentation fault
