Summary: Black screen on Plasma 6 login after changing theme
Classification: Plasma
Product: plasmashell
Version: 6.0.2
Platform: unspecified
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: generic-crash
Assignee: plasma-b...@kde.org
Reporter: bsnapc...@gmail.com
Target Milestone: 1.0
Application: plasmashell (6.0.2)
Qt Version: 6.6.2
Frameworks Version: 6.0.0
Operating System: Linux 6.7.6-201.fsync.fc39.x86_64 x86_64
Windowing System: Wayland
Distribution: Nobara Linux 39 (KDE Plasma)
DrKonqi: 6.0.2 [CoredumpBackend]
-- Information about the crash:
I wasn't doing anything noteworthy, just downloading and trying theme's via the
built in "get new" function for downloading themes. I tried going back to the
original Breeze Dark theme, and it did not apply correctly. I figured this
could be remedied by restarting the machine, but after logging in to my user
account, I was greeted with a black screen and a "Plasmashell - Crash Handler"
message. I can open programs via terminal, but I have no desktop background
picture, and no taskbar. If I hover my mouse over where the taskbar would be,
and get about 10 or more Plasmashell crash handler messages. I've tried to
updates, and while I can update fine, it doesn't fix the issue. I'm using
Nobara 39.
The reporter is unsure if this crash is reproducible.
