Brightness On Thinkpad x61s running Debian
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. So I ended up with an additional set of acpi rules, that 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 :-)
