Bug ID: 402933
Summary: Turn off the monitor and on again disconnects Plasma
session on Wayland
Product: kwin
Version: git master
Platform: Archlinux Packages
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: wayland-generic
Assignee: kwin-bugs-n...@kde.org
Reporter: m...@rainer-finke.de
Target Milestone: ---
Turn off the monitor and on again always disconnects the Plasma session on
Wayland and you are back to the SDDM login screen. As soon as you turn on the
monitor kwin will crash somehow. The issue exists only with my external GPU
(AMD RX 480), the issue happens since a long time but in the past in most cases
it froze the system (this driver bug is solved now). The same issue happens as
well if power management is active and Plasma turns off the screen after some
time and you wake up the system later on. See logs below based on kwin-git and
kscreen-git from 2019-01-06.
STEPS TO REPRODUCE
1. Turn off the monitor
2. Turn the monitor on again
OBSERVED RESULT
Kwin crashes all the time, Plasma session is disconnected and you are back to
the SDDM login screen. You can open only a new session now.
EXPECTED RESULT
Screenlocker allows you to unlock the open Plasma session and you can continue
to work with the previous open applications.
