Bug ID: 350766
Summary: kwin crash after resume
Product: kde
Version: unspecified
Platform: unspecified
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: unassigned-bugs at kde.org
Reporter: handspam at stibo.com
Application: kwin_x11 (5.2.2)
Qt Version: 5.4.1
Operating System: Linux 3.19.0-25-generic x86_64
Distribution: Ubuntu 15.04
-- Information about the crash:
- What I was doing when the application crashed:
I have my laptop (Lenovo T430) in a docking station with monitor attached at
work. I suspended it before leaving and then resumed it at home. The greet
process crashed first and then kwin crashed when I tried to use the task
switcher (alt-tab).
I already disabled compositing, since otherwise I never had a task bar/switcher
after resume.
Everything worked better on kubuntu 14.04, I only had these issues with 15.04
(though I have occassionally seen kwin crash on 14.04 too).
-- Backtrace:
Application: KWin (kwin_x11), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
