Description Diego Marino 2019-06-23 17:14:14 UTC

Description of problem:
Logging off, then logging in a session often causes freezes: cursor moves, black screen. Logging in with tty2 and "startx" is the only workaround without rebooting.

Version-Release number of selected component:
kf5-kglobalaccel-5.59.0-1.fc30

Git commit 6ce8f434139f47e6a71bf0b68beae92be8845ce4 by David Edmundson.
Committed on 29/09/2023 at 16:31.
Pushed by davidedmundson into branch 'master'.

Use systemd to handle more of the shutdown

Previously we killed kwin manually, then tried to exit the session.
This is racey as kwin will close all connections, before systemd has
realised that the session is ending this can cause all apps to restart.

Also closing plasma-workspace-wayland.target is ineffective, closing the
graphical-session implicitly brings down the session more explicitly.
It'll close the other targets and services.
Related: bug 473824, bug 450531, bug 451939, bug 450320, bug 434403

Tested by looking at `coredumpctl list` after a logout and seeing it go from 10 entries of silly aborts restarting without a display server to 3, with different unrelated causes.
