Debian squeeze on Samsung N220: almost working very well but no control of brightness
I recently acquired a Samsung N220 laptop (Intel Atom N450 chip, 10"
screen, etc). After some playing around, yesterday I was able to
install Debian squeeze on this system and managed to get even wireless
working (once I tracked down the firmware required). Sounds works as well.
Unfortunately, none of the "Function" keys work. I don't particularly
care about most of them as I can adjust or control things from the
shell for most functions that I require. However, there is one thing

brightness of the display. The display is stuck at a fairly low level
of brightness, suitable only for use in a dark room.
Can anybody please suggest what I might be able to try to control the
brightness levels? At best, it would be to gain control via the blue
function keys but direct commands are fine as well.
I can send all appropriate HAL/USB/PCI info but I don't think any of
it is relevant. The display controller, just in case, is an Intel
In case this data point matters, ubuntu's latest version did work in
this regard but I cannot determine what was different about that
installation. (I prefer Debian to ubuntu for a number of reasons)
