The above post helped me to set backlight dimmer on my Asus EEEPC 1101HA, running ubuntu 12.04.
But the commands have to be changed somewhat to actually change the file /sys/class/backlight/psb-bl/brightness
2) chmod 666 /sys/class/backlight/psb-bl/brightness
to give yourself permission to read/write (711 actually only gives execute permission)
3) Using a text editor (I use vi) gives Fsync errors (/sys is not a normal filesystem), so use the shell to write to the "file" instead:
First choose the number, for example 50. The command is:
echo 50 >| /sys/class/backlight/psb-bl/brightness
