Bug Description

After logout, switching to another login screen or shutting down the monitor brightness is set to its lowest level, making it rather hard to read in bright environments. Pressing a brightness key once (up or down does not matter) sets the monitor brightness to its highest level. Therefore it seems, that a vt switch leaves the brightness level at a undefined state and after triggering a manual change, it switches to some default setting.

On a closer look, pressing the brightness up or down key makes a difference: With the up key brightness is set to its highest level, with the down key its set to the highest level - 1.

Btw. the newest driver 2:2.99.916+git20141006.ec2b9ac8-0ubuntu0sarvatt shows the same behavior.
