Make "Turn off monitor(s)" work on Wayland too

[stefonarch]

In ~/.config/lxqt/power.conf several commands can be used for specific compositors:

#kwin
monitorOffCommand=kscreen-doctor --dpms off
#niri
monitorOffCommand=niri msg action power-off-monitors
#hyprland
monitorOffCommand=hyprctl dispatch dpms off

Maybe there are other commands too for sway, wayfire ecc, like wlopm which needs wlr-output-power-management-v1 and monitor names.

The working commands could be included, and a text input field added in the GUI for them.
monitorOffCommand=xset dpms force off for X11 could be selected automatically.

Maybe "power off monitors" could also be separated from suspend: example power off monitors after 5min, suspend after 10min.

It should be done in parallel to changes to liblxqt: /usr/share/lxqt/power.conf belongs to the latter.

Shall we close this now or wait for things to come?

[tsujan]

It's basically implemented now; we can't do more. So, I think this can be closed.

Of course we'll add more recommended commands if they appear, but users are free to use commands of their choice.
