I also have installed the quickshell eopkg from unstable for testing purposes.
Something is strange, and I haven't figured it out yet.
I noticed that with the eopkg, which is v0.2.1, power management doesn't work properly anymore. System does not blank screen or trigger lock screen automatically anymore with dankmaterialshell.
dankmaterialshell emits this error on startup:
WARN qml: IdleService: IdleMonitor not available - power management disabled. This requires a newer version of Quickshell.

requires newer Quickshell version
which is weird, because 0.2.1 is latest and it worked fine with 0.2.0
Then I thought maybe I need to update dankmaterialshell as well. But that brought more problems like dark/light mode not working properly.
Had trouble to reverse everything back to the state that I had. Also build quickshell version 0.2.1 myself, with the same issues. So probably not a packaging problem.
Quickshell and dankmaterielshell also seem under heavy development with many changes.
For now I am back on 0.2.0 with also an older dms version.
Gotta be careful with matugen and dynamic theming on newer dms versions. Cause this also changes ~/.config/gtk-3.0/4.0 which also affects GNOME. Had even trouble with dark/light mode toggle under GNOME.
