Bug ID: 427729
Summary: Change theme with "use desktop layout theme" renders
desktop to black screen
Product: plasmashell
Version: master
Platform: Archlinux Packages
OS: Linux
Status: REPORTED
Severity: critical
Priority: NOR
Component: Global Theme packages
Assignee: plasma-b...@kde.org
Reporter: adelinoara...@adelinoaraujo.com
CC: plasma-b...@kde.org
Target Milestone: 1.0
SUMMARY
updated to 5.20, rebooted, changed the theme for some I can't remember what it
was, because I had a few installed. But the problem is to change the theme and
select the option "use desktop layout theme". Every time I selected this option
when changing theme, I always noticed that the Super key was disabled.
This time, I choose "use desktop layout theme" just to see if this was fixed
and it was a total crash.
STEPS TO REPRODUCE
1. select (almost) any theme with "use desktop layout theme"
2. apply
3. desktop theme changes and 2 seconds later disappears; desktop is a dark,
nothing on it
OBSERVED RESULT
both monitors are black, nothing on screen, no icons, no taskbar, no menus, no
right-click menus, nothing
EXPECTED RESULT
theme was applied and kept running plasma with the new theme

ADDITIONAL INFORMATION
I cannot figure out what was the theme but this problem was on previous
versions of plasma, but before I always lost the taskbar and Super key, but I
managed to open systemsettings and change to Breeze and recover. This time,
even if you change the systemsettings back to another theme with "use dekstop
layout theme" and reboot, the desktop appears, the taskbar appears for 2
seconds and it's gone. I end up with a black screen. I also tried to edit some
settings file to start plasma with breeze theme but nothing, it start with the
theme that broke Plasma, that has the taskbar on top.
Plasma should make sure that the theme is applied and it is working. At least
had a terminal option to start over with the default settings, so we could
recover from this critical situation.
I managed to reboot and change some files by using another session ctrl+alt+f2
or f3. I also had xfce4 installed that I used to try to edit some files I found
on .config but I could not find a single place where it says what files are the
configuration of plasma.
This is not the first time that changing themes breaks plasma, but once again I
will install plasma again soon as I backup my docs.
Selected critical severity because it renders the computer to blank.
