Package: linux-image-2.6.26-1-amd64
Version: 2.6.26-12
Severity: important

When I run my Samsung Q45 laptop on battery power, the screen is dimmed to
save power. This is fine, except that it is dimmed too much--the screen becomes
so dark that it is basically unusable if there are any external sources of
light (the sun, or room lighting when it's night time).

The dimming happens in a weird way--it seems to redefine the value of 100%
brightness, as if I run 'xbacklight --get' while the screen is dark, it still
returns '100'.

FYI, xbacklight sets the backlight via the X11 RANDR protocol extension.

/sys/class/backlight is empty on this machine.
