Bug ID: 475721
Summary: KDE session doesn't start when attempting to login
(applying kscreen config failed!)
Classification: Plasma
Product: kwin
Version: 5.27.8
Platform: Fedora RPMs
OS: Linux
Status: REPORTED
Severity: critical
Priority: NOR
Component: core
Assignee: kwin-bugs-n...@kde.org
Reporter: ja...@jamesnorth.net
Target Milestone: ---
SUMMARY
This issue relates to the two weeks I spent on Fedora 38 KDE. Every time I
rebooted my computer, I couldn’t login to KDE, even after waiting 2 hours.
Usually, it’s just a black screen for 2-3 minutes, but the last time, I
couldn’t login at all. I can’t show you the full logs as I couldn't get to a
desktop on this machine, but journalctl -r spams:
kwin_core: Applying Kscreen config failed!
I also saw:
kwin_wayland_drm: Failed to create gamma blob! Invalid argument
I have a NVIDIA RTX 2060S card and I was attempting to log in to KDE Wayland. I
just updated via Discover before rebooting, which performed an offline update.
STEPS TO REPRODUCE
1. Reboot the computer.
2. Ty to login.
OBSERVED RESULT
I see a black screen for over 2 hours with nothing happening, and the KDE
session never starts.
EXPECTED RESULT
I can login and the session starts.
SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Fedora 38 (Oct 15th)
(available in About System)
KDE Plasma Version: 5.27.8
KDE Frameworks Version: 5.111.0
Qt Version: 5.15
ADDITIONAL INFORMATION
Sorry for not being able to provide specific versions. I uninstalled Fedora
because of this recurrent issue, but I thought I should report it as it is
quite a severe error. As such, I'm not available to troubleshoot it because
this doesn't occur on Arch Linux. I ran into several other bugs related to
KDE/KDE programs that aren't present on Arch and documented them but unsure
whether I should report them because I'm no longer using the system...
