<br>(notably Thinkpads) have their own backlight controllers that aren't wired up<br>to the GPU registers at all. In the Thinkpad case there's a kernel driver<br>you can load to get access to the backlight.</blockquote>
<div><br>Yep, I guessed that I might have ended up with some unsupported platform. Any ideas how I can help the developers change it into supported? :-) What information is needed, and where should I file it? (As I think I mentioned earlier, this is fujitsu-siemens lifebook p7010).
