Public bug reported:
Binary package hint: gnome-power-manager
I can control display brightness using the keyboard but the settings in
Power Manager preferences, seem to be ignored. For example, when I
unplug the AC power, the screen dims, but when I plug it back in again,
the screen notifier shows the brightness increasing to about 90% (it is
set to be 100% on AC power) but in fact the screen remains dimmed and
does not actually increase. If I unplug the AC power again, the display
brightness decreases and so on until after unplugging the AC power four
times, the display brightness is at its lowest level and plugging in AC
power makes no difference to the actual brightness. I can rectify this
by using the FN-F11 keys.
I'm running the latest Hardy updates on a Lenovo 3000 N100. I've
attached some logs. This is not a recent problem but started occurring a
few weeks ago.
Thank you.
