Bug ID: 362496
Summary: KWin crashed when unifying outputs
Product: kwin
Version: 5.6.3
Platform: Gentoo Packages
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: kwin-bugs-n...@kde.org
Reporter: k...@kaishome.de
Application: kwin_x11 (5.6.3)
Qt Version: 5.6.0
Frameworks Version: 5.21.0
Operating System: Linux 4.5.2-gentoo x86_64
Distribution: "Gentoo Base System release 2.2"
-- Information about the crash:
- What I was doing when the application crashed:
I've temporarily set my monitors (DVI monitor + HDMI TV) from clone to separate
outputs, that worked without problems. Tho, later, when I returned to unifying
both outputs (in German "Anzeigen vereinheitlichen"), KWin crashed and
respawned itself.
-- Backtrace:
Application: KWin (kwin_x11), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
