Public bug reported:
Binary package hint: gnome-power-manager
I've set up gnome-power-manager to "Dim when Idle" and "reduce when on
battery" to manage my display.
Sometimes, while i'm in dark conditions(with or without AC) or want to maximize
battery life, I use the keyboard shortcuts (fn-home + fn-end on a T42) to dim
the display to it's minimum. However, mostly while reading stuff and thus not
interacting and letting the 'dim timer' kick in, in stead of trying to dim the
display, it turns quite bright for a second and then dims it again, but to a
higher setting then what it was at. Not only does this blind me, it is also
highly annoying.
This also happens during boot, when I have the setting dimmed and just before
login the power-manager backend kicks in to do it's dim-undim magic.
The first thing gnome-power-manager should do (or it's backend) is try
to determine what the current backlight setting is. I know this is
possible on a IBM T42 as this issue wasn't here 2 release ago.
