Bug#799837: sddm becomes unusable after logout
Package: sddm
Version: 0.12.0-4
Severity: critical
Justification: breaks the whole system
Dear Maintainer,
I normally use a laptop where I am the single user, so I only login once
in sddm, and I use "shutdown" when I (rarely) need to turn it off.
Today I needed to logout and login again. What happened was that:
1. KDE took several minutes to disappear
2. After it disappeared the screen went off! Backlight off and completely
dark.
With great difficulty I managed to reach a virtual terminal (the system was
very unresponsive) and noticed that there were no longer any processes from
my session running. sddm was running.
I attach some logs in hope that they can help.
I think it's a really terrible behaviour.
Best
