Bug ID: 437693
Summary: KWin crash on login (after a major security bug that I
didn't know was possible)
Product: kwin
Version: unspecified
Platform: Neon Packages
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: kwin-bugs-n...@kde.org
Reporter: thederpylla...@gmail.com
Target Milestone: ---
Application: kwin_x11 (5.22.80)
Qt Version: 5.15.2
Frameworks Version: 5.83.0
Operating System: Linux 5.4.0-73-generic x86_64
Windowing System: X11
Drkonqi Version: 5.22.80
Distribution: KDE neon Unstable Edition
-- Information about the crash:
- What I was doing when the application crashed:
Logging in after doing a system upgrade that fixed the other bug that I
encountered shortly before this
- Unusual behavior I noticed:
I encountered a bug where it skips the display manager entirely and throws me
into a logged in blank desktop (The KDE Plasma startup animation never played
either.) where the only window that opens is QjackCtl (I have it set to open on
startup.) I was able to fully access all of my applications with the usage of
Ctrl+T and the package names. I also tried logging out and back in with
Ctrl+Alt+Del and it took me to the display manager but when I tried to login it
would freeze after the startup animation was about half way done. This bug also
persisted after reboot. I ended up using TTY3 to perform a full system upgrade
(after attempting to use 'pkcon upgrade' in a terminal (on the strange black
screen desktop,) but it would hang when it attempted to install the packages,
so I had no choice but to use 'apt dist-upgrade' to attempt to save my system.
After the reboot, I was greeteed by the display manager, (I've never been so
happy to see it in my life lol,) but when I logged in the animation got to
about 75% through then the animation stopped for about 5 seconds and then KWin
crashed and it finished starting up as normal. I'm not sure if either of these
bugs are related in anyway but it's weird how I encountered them one right
after the other.
TLDR: KWin crashed on boot after encountering a bug that threw me into a logged
in but messed up desktop that gave me access to my applications via the
terminal keyboard shortcut and the package name. (I have a photo of the desktop
bug that I sent to my friends but I didn't think to take a screenshot because I
planned on doing a fresh install)
- Custom settings:
So far the only changes I've made to my settings is that I enabled dark mode
and applied a theme.
The crash can be reproduced every time.
