Brightness Control on-screen display won't disapp
There is a kernel bug. The drivers/input/atkbd.c file has a quirk in it
for Dell laptops which needed to be expanded to cover more models. It
was changed initially to match any laptop manufactured by "Dell Inc.",
but this then broke ones manufactured by "Dell Computer Corporation". So
you either do
Same here on a Dell XPS M1330 with up-to-date Ubuntu 8.10 after fiddling
with power management settings (hdparm stuff). The brightness applet
(using mouse) works fine, but through the Fn-keys the display dims all
the way down (if not hitting up fast). ctrl+F1 and then back to ctrl7
works fine.

Same problem here on a Dell Vostro 1400 with an Nvidia GeForce 8400M GS
card. The problem occurred when I plugged in the power supply, prompting
the display to change to maximum brightness. The brightness can still be
altered by the brightness hotkeys, but the brightness display does not
disappear
Update 2008-10-27
As with todays update status, the on-screen display still won't disappear.
But when hitting the buttons fast, it updates. Hitting the key one time and
waiting a few seconds the on-screen display brightness bar grows to the max or
min value depending on decreasing/increasing brig
