I have problems using the brightness control on my acer aspire 3935 (w/ Ubuntu 12.04) - it seems to work for the system (the brightness bar goes up and down), but nothing actually happens (actual brightness don't change). Can you help me? Thanx!

Run:
gksudo gedit /etc/default/grub
Find this line:
GRUB_CMDLINE_
Change it to:
GRUB_CMDLINE_
Save the new file, close gedit and run:
sudo update-grub
Reboot to test. Source:

Or you can simply run this 2 commands to a terminal
(1) sudo sed 's/GRUB_

I'm having the same problem with my Aspire 3680. Have tried the above suggestions, result negative. Have had no problem with previous Ubuntu distros and am currently using 12.04. When I use the slider on Adjust Brightness, nothing happens: thed isplay remains dim. Any further suggestions,people?
