Bug ID: 405883
Summary: kwin crash after resume (dual displays)
Product: kwin
Version: 5.13.5
Platform: Ubuntu Packages
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: kwin-bugs-n...@kde.org
Reporter: pasthe...@gmail.com
Target Milestone: ---
Application: kwin_x11 (5.13.5)
Qt Version: 5.11.1
Frameworks Version: 5.50.0
Operating System: Linux 4.18.0-17-generic x86_64
Distribution: Ubuntu 18.10
-- Information about the crash:
- What I was doing when the application crashed:
Initiated resume.
- Unusual behavior I noticed:
One of the monitors/displays went blank and eventually displayed the
no-signal OSD (then turned off the screen because power saving), during this on
the other display the Plasma greeter/login screen was unresponsive (no login
dialog, only the background and an immovable mouse pointer).
-- Backtrace:
Application: KWin (kwin_x11), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
