Public bug reported:
Binary package hint: gnome-power-manager
When I change the screen brightness level in the power management
preferences, the brightness level changes correctly as I move the
brightness slider, and the brightness notification on screen also
correctly reflects the brightness. However, 1 to 2 seconds after
changing the brightness, the screen brightness goes back down to the
lowest level. The on screen brightness indicator (but not the slider
control) correctly reflects the progress down to the lowest level. If I
change the brightness using the brightness adjustment on the keyboard,
the adjustment stays until I logout or restart. The brightness also
reverts to the lowest level each time the login screen displays and
after gnome has loaded when login is complete. The on screen brightness
indicator tracks the brightness as it moves down to the lowest level.
My laptop is a Nexlink Versatility 15.4C XP using Ubuntu Maverick with
latest updates as of 01/22/2011.
