Description C0D3 M4513R 2021-10-02 00:50:49 UTC 
SUMMARY

The Change of Brightness per Key-press is hard-coded in this program.
My proposal is to add a way to manually change this, via a dbus-interface or a config-file or System Settings

STEPS TO REPRODUCE
1. Press Screen Brightness Down
2. Observe -5% change.
3. Run `qdbus local.org_kde_powerdevil /org/kde/Solid/PowerManagement/Actions/BrightnessControl org.kde.Solid.PowerManagement.Actions.BrightnessControl.brightnessSteps` and verify it outputs 20

Additionally, it would be nice if the lowest 5% were done by increments/decrements of 1%. In a dark screen, 5% is too high and 0% is turned off (actually, 1% is still a bit too high on this screen for my eyes, being able to set 0.5% would be perfect).

My current workaround it to use the wheel on the battery icon (which does increments of 1%), or setting the /sys/class/backlight/*/brightness file.

I meant in a dark room, not screen, sorry.
