Bug ID: 360563
Summary: black screen on session restore until removing
~/.local/share/kscreen
Product: KScreen
Version: 5.5.4
Platform: Other
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: common
Assignee: se...@kde.org
Reporter: martin.steigerw...@teamix.de
On logging in yesterday after plugging to the second screen at work I got a
black screen on logging. After removing ~/.local/share/kscreen for the affected
user login worked just fine.
Reproducible: Sometimes
Steps to Reproduce:
I have no idea how to reproduce this reliably. It tends to happen on changing
multiscreen setups between home and work or no second screen when holding a
training. I have an external Fujitsu Display both at home and at work,
different ones.
Actual Results:
Black screen.
Expected Results:
As long as there is a suitable display to display things on, and in a laptop
there always is a suitable display, the internal one, on session login display
something useful.
I will attach the broken ~/.local/share/kscreen
This happened with mostly Plasma 5.5.4 + self compiled KDE Frameworks + KDEPIM
on Debian Sid with a setup similar like this one (the display at work is a
different Fujitsu display):
