Steps to reproduce: 0) ensure your keyboard backlight is on, and gdbus call --system --dest org.freedesktop.UPower \ --object-path /org/freedesktop/UPower/KbdBacklight \ --method org.freedesktop.UPower.KbdBacklight.GetBrightness returns a value != from 0. If not, just call the SetBrightness method with a positive value, to turn on the backlight. Now turn off the keyboard backlight (or set it to another level) using the laptop keys, and run: gsettings set org.gnome.desktop.session idle-delay 1 to make things easier to test. 2) Wait one second and the screensaver should start. Wait the screen to be turned off. If you just changed the brightness level at the step above, once the screen is turned off, also the keyboard backlight should be turned off too. 3) Now press a key or move the mouse. Expected behavior: 4) The keyboard backlight should be set back to the previous level (so it should stay off or go back to the level you set before the idle timeout happened). Actual behavior: 5) The backlight is set to the level it had at point 0).
