Bug Description

Binary package hint: hotkey-setup

When I push Fn+End the brightness goes to the lowest setting.

When I push Fn+Home the brightness goes to the highest setting.

All intermediate steps are skipped.

When I push Fn+End twice (with 0.5 second pause) or Fn+Home twice the lowering or raising of the brightness is cancelled somewhere halfway. This is clearly visible in the Gnome brightness OSD.

Changing brightness through Power Manager works fine. All intermediate steps are available.

Other hotkeys volume work fine.
