Bug Description
Backlight brightness control does not work on my Samsung Q45 with Nvidia GForce 8400M. The Fn+Pg_up/Pg_down hotkey stops working after the acpi stuff is loaded. (Ok they do something but thats only switching between the both lowest brightness settings)
echo VALUE > /proc/acpi/
does not change the brightness of the display but saves the value to /proc/acpi/
Update to the new nvidia driver does not help. But after the update pressing the hotkeys does really nothing under X. While working without X the behavior is still the same.
nvidia binary driver 100.14.11 and 100.14.19 and the actual acpi stuff.
