works well, returns 0, 1, or 2, depending on keyboard backlight level OFF, DIM, FULL.
But gdbus call --system --dest org.freedesktop.UPower --object-path /org/freedesktop/UPower/KbdBacklight --method org.freedesktop.UPower.KbdBacklight.SetBrightness i
switches backlight to full power independently of parameter i. Even backlight timeout is deactivated: backlight just does not switch off.
This deactivated timeout "setting" made by Ubuntu is persisted. Even if I reboot into DOS or BIOS setup, backlight just stays on. I have to setup the timeout vale in BIOS again to activate the timeout function.
