Public bug reported:
Binary package hint: gnome-power-manager
I have a Dell Latitude D410 laptop running the latest testing version of
Jaunty.
While I'm typing here, I have the laptop on AC power. I find the screen
keeps dimming down to about 60%. I then use the hotkey to brighten the
screen up again. Within a minute or two it has dimmed back down again.
The power management settings "On AC power" are set to
Put computer to sleep when inactive: Never
When laptop is closed: blank screen
Put display to sleep when inactive for: 15 minutes
Set display brightness to: 100%
Dim display when idle: unchecked
"On Battery Power":
Put computer to sleep when inactive: Never
When laptop is closed: blank screen
When battery power is critically low: Shutdown
Put display to sleep when inactive for: 11 minutes
Reduce backlight brightness: checked
Dim display when idle: checked
The gnome tray applet confirms that I do have AC power on.
This problem is consistently irritating. I'm in a bright room and
really need the full backlight.
