brightness adjustment still freezes my system, however i did find some
workarounds
- in gnome power management disable the function to reduce brightness when
running on battery
- you can change the brightness in the nvidia-settings tool
some other observations:
- i even tried kernel 2.6.39 and
issue is back for met to.
every time i change brightness it crashes
