Bug ID: 398965
Summary: Kwin won't start with 100% CPU
Product: kwin
Version: unspecified
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: kwin-bugs-n...@kde.org
Reporter: m...@nbrogi.com
Target Milestone: ---
SUMMARY
STEPS TO REPRODUCE
Try to launch Wwin via terminal
EXPECTED RESULT
Kwin should start
ACTUAL RESULT
Kwin doesn't start, doesn't report errors, and uses 100% CPU
SOFTWARE VERSIONS
(available in About System)
KDE Plasma Version: N/A (running on Xfce)
KDE Frameworks Version: Kwin v. 5.12.6
Qt Version: 5.9.5
ADDITIONAL INFORMATION
Following no particular event or configuration that I can remember, I am all of
a sudden unable to run Kwin.
When I try to start it, it starts using 100% CPU and hangs with me having no
window manager. In addition, I'm unable to kill the process with "killall
kwin", and I actually have to look up the pid and do "kill -9".
I tried purging and re-installing, to no avail, even after removing ~/.kde/.
What could be the cause, or a way to figure out what it's doing..? The terminal
doesn't print ANYTHING, it just hangs.
The same thing happens if I create a brand-new user and try to start Kwin from
a brand-new session.
