Brightness On ThinkPad X61s running Debian

Somehow after a fresh installation of Debian Testing "Squeeze" I was not able to control the LCD Brightness with FnPos1 and FnEnde any more. # acpi_listen did show that the corresponding ACPI events were generated. I ended up with this additional set of acpi rules to solve the problem:


/etc/acpi/thinkpad_video_brightnessup.sh 

#!/bin/sh
# /etc/acpi/thinkpad_video_brightnessup.sh
echo $(( $(grep current /proc/acpi/video/VID1/LCD0/brightness | cut -d ' ' -f 2)+10)) > /proc/acpi/video/VID1/LCD0/brightness


/etc/acpi/thinkpad_video_brightnessdown.sh 

#!/bin/sh
# /etc/acpi/thinkpad_video_brightnessdown.sh
echo $(( $(grep current /proc/acpi/video/VID1/LCD0/brightness | cut -d ' ' -f 2)-10)) > /proc/acpi/video/VID1/LCD0/brightness


/etc/acpi/events/video_brightnessdown 

# /etc/acpi/events/video_brightnessdown
event=video LCD0 00000087
action=/etc/acpi/thinkpad_video_brightnessdown.sh


/etc/acpi/events/video_brightnessup 

# /etc/acpi/events/video_brightnessup
event=video LCD0 00000086
action=/etc/acpi/thinkpad_video_brightnessup.sh


Restart acpid and the brightness keys work again :-)
