Bug ID: 438090
Summary: Segmentation Fault on Logout
Product: kwin
Version: 5.20.5
Platform: Gentoo Packages
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: core
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
SUMMARY
SDDM / Login works OK when system first boots up. If I log out, I can't log in
again. Much discussion in Gentoo forums. See
https://forums.gentoo.org/viewtopic-t-1136583.html and also
https://forums.gentoo.org/viewtopic-t-1135770.html.
STEPS TO REPRODUCE
1. Boot the system and log in.
2. Log out.
3. Segmentation fault in kwin; can't log in again.
OBSERVED RESULT
I can't log into my Plasma session unless I restart sddm.
EXPECTED RESULT
I should be able to log out, then log back in again. It worked until a couple
of days ago. I suspect "qtcore" and/or "qtgui", which were recently upgraded in
Gentoo.
SOFTWARE/OS VERSIONS
Windows:
macOS:
Linux/KDE Plasma:
(available in About System)
KDE Plasma Version: 5.20.5
KDE Frameworks Version: 5.80.0
Qt Version: 5.15.2
ADDITIONAL INFORMATION
I'm reporting this as a bug in Plasma, with the X11 windowing system. But it
also appears to be killing the Wayland windiwing system. I usually don't use
Wayland, but it used to work, and now it doesn't. I can't even get a decent
error message out of Wayland. I also have XFCE configured ... amaxingly enough,
I was able to get some screenshots of Drkonqui after kwin had crashed by
logging in to XFCE and using those tools. Screenshots are attached.
