Bug ID: 399499
Summary: KWin Seg Fault on Startup
Product: kwin
Version: 5.13.5
Platform: Neon Packages
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: kwin-bugs-n...@kde.org
Reporter: rdo...@gmail.com
Target Milestone: ---
Application: kwin_x11 (5.13.5)
Qt Version: 5.11.1
Frameworks Version: 5.50.0
Operating System: Linux 4.15.0-36-generic x86_64
Distribution: KDE neon User Edition 5.13
-- Information about the crash:
- What I was doing when the application crashed:
Booting to desktop
- Custom settings of the application:
Default settings for KWin (recent reformat) that come with KDE Neon 5.13
(neon-useredition-20181004-1723-amd64.iso). The only related item installed is
the latest nvidia binary drivers (390.48) for the GTX 670M.
Initially the desktop appeared to have not booted at all, but switching to tty2
and back restored it. No unusual behavior since. This has happened
consistantly on several startups.
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".
