LCD Brightness
This worked for my X61:
Once your brightness keys work, you can set the brightness by writing to the procfs:
# echo 100 > /proc/acpi/video/VID1/LCD0/brightness
using a script and acpid events. However this may lead to a bug (screen flickers) described on the Debian mailing list [[1]]. This bug is related to the X server as it does not occur on the tty1. To fix it change your xrandr backlight control to native:
$ $xrandr --output LVDS --set BACKLIGHT_CONTROL native
For my X61, these following scripts from this japanese site helped:
% cat /etc/acpi/video_brightnessdown.sh #!/bin/sh xbacklight -dec 10%
% cat /etc/acpi/video_brightnessup.sh #!/bin/sh xbacklight -inc 10%
