My laptop screen is sometimes not bright enough and I have reach the top of the brightness according to the brightness control that is on the keyboard. The gnome applet brightness control has never worked either.
But today I’ve found an utility (which was on all my previous linux distrib, I guess) : xgamma.
Now I can adjust my brightness with this command:
xgamma -gamma 1.4
1.4 is a number between 0.100 and 10.000, default value is 1.
To make this modification permanent, you have to add a line to Monitor section of xorg configuration file (/etc/X11/xorg.conf) :
Gamma 1.04
with your correct value instead of this 1.04.

I’ve tried the gutsy beta last week on an old toshiba s3000 laptop. The live cd worked like a charm, so I decided to install gutsy on my disk.
After the install and reboot, it was still working perfectly : very short boot time, gnome with compiz running very smooth. Then I noticed there were some updates (139 packages, not surprising for a beta version), and I did them.
Unfortunately, after reboot, I had a black screen instead of the GDM screen. Actually, GDM starts (I can hear the sound) but the screen is black, as if it was asleep. I even manage to login (in ‘blind mode’) !
By chance, I can access to the other tty’s and login in CLI mode.
