I am using an ASUS M50Sa laptop which I've seen (and experienced) always has problems with the light sensor making the brightness very dark and uncontrollable. When I was using Jaunty I was able to fix it using (if I remember correctly) the advice given by hotweiss in this post.
After updating to Karmic I suddenly lost control again. I tried to go through his commands again but the final command yields:
update-rc.d: warning: /etc/init.d/brightness missing LSB information
update-rc.d: see <http://wiki.debian.org/LSBInitScripts>
System start/stop links for /etc/init.d/brightness already exist.
I'm not exactly sure what that means, so any help getting the stupid light sensor to stop messing up the brightness would be greatly appreciated.
Also, any time I hibernate or suspend, when I try to turn the computer back on it shows that it's booting up and everything looks fine, and then the screen goes black except for the mouse pointer, which I am able to move, and nothing else happens. The only way I've figured out how to get out of this is just to manually turn it off with the power button and reboot. Is there a way to fix this? I'd really like to be able to hibernate and suspend.
