I can check tomorrow again. However=E2=80=A6 after I wrote "512" to the "/var/lib/initscripts/brightness" file, brightness is set correctly after=20 reboot. So I am not sure I can reproduce the original condition after=20 the update anymore. So or so, I think it would be good to ensure a minimum brightness level,=20 as a completely blank display can only be fixed with a live Linux, SSH=20 access or some other out of band management access. Best, =2D-=20 Martin
