Bug ID: 355118
Summary: Crash after removing external monitor while being on
standby
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: leonard at lausen.nl
Application: kwin_x11 (5.3.0)
Qt Version: 5.4.1
Operating System: Linux 3.19.0-31-generic x86_64
Distribution: Netrunner 16
-- Information about the crash:
- What I was doing when the application crashed: I have configured my setup to
only use an external monitor when the lid of the laptop is closed and an
external monitor is connected.
Removing the external monitor while being on standby leads to crash or to
unusable DE
I'm using a recent version of Netrunner
The crash can be reproduced every time.
-- Backtrace:
Application: KWin (kwin_x11), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
