Bug Description
Hi there!!
I have a fujitsu esprimo u9200 and the brightness up/down key aren't behaving properly, since they increase/decrease to much.
cat /proc/acpi/
levels: 0 1 2 3 4 5 6 7
current: 7
If I press the key up key one time, it will decrease to 4, then to 1 or 0 and the to 0. Usually that means going from too bright to too dark... the brightness applet works fine, full control over the different levels.
lshal -m, pressing one up one down:
22:58:22.325: computer_
22:58:32.482: computer_
acpi_list, one up one down:
video LCD 00000086 00000000 // that's up
video LCD 00000087 00000000 // that's down
xev also doesn't seem to report anything abnormal
UPDATES:
sudo modprobe -r video solves the problem, it will go up/down just fine. However, acpi_listen and lshal -m won't report anything. Same way, without the video module, brightness won't go down automatically when in battery.
lshal -m reports:
modprobe -r video
23:19:02.059: computer_backlight removed
23:19:02.071: computer_
modprobe video
23:18:59.710: computer_backlight added
23:18:59.809: computer_
Also, has running without the video module any side effects in performance?

A quick update: may this be a bug upstream?
In Intrepid it worked fine, but it won't in Jaunty, Mandriva One 2009 nor Debian 5.0.1.
