[sf-lug] how to disable screen dimming due to light sensor in exo-pc running ubuntu

[Michael Shiloh]

1) anyone running any flavor of ubuntu on an exo-pc? i'd love to 
exchange ideas.

2) exo-pc has a light sensor which automatically dims the screen in dim 
light. i want my screen bright all the time. how can i disable the 
automatic dimming?

my absolutely horrible hack using xbacklight is:

michael at exopc:~/Ubuntu One/misc/hints$ while [ 5 -lt 10 ]
 > do
 > xbacklight -set 100
 > done

it works but flickers sometimes.

i've heard that the dimming is controlled via apci. is there a way to 
control acpi?
