Bug ID: 371272
Summary: Crash while loading plasma
Product: kde
Version: unspecified
Platform: unspecified
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: unassigned-b...@kde.org
Reporter: d.h.j.tak...@xs4all.nl
Application: plasmashell (5.8.1)
Qt Version: 5.7.0
Frameworks Version: 5.26.0
Operating System: Linux 4.7.6-1-default x86_64
Distribution: "openSUSE Tumbleweed"
-- Information about the crash:
- What I was doing when the application crashed:
Nothing yet, plasma was loading when it crashed
- Unusual behavior I noticed:
I just upgraded from Plasma 5.7 to 5.8 and the display configuration was messed
up: The plasma widgets (panels) apparently moved to the laptop display, which
was disabled (lid closed). The external, primary display was empty, as if the
two display configs were swapped. By enabling the laptop display and switching
the primary display hence and forth, the panels moved back to the correct
display. But, the external display froze in the process. Windows could not be
interacted with or moved at all. Logging out and loading KDE again appeared to
restore everything back to normal, as it was on Plasma 5.7, but resulted in a
crash while loading.
- Custom settings of the application:
Docked laptop with its display disabled, external display as primary.
-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
