I just bought a used Dell Inspiron Mini 1010...and when I hit the brightness buttons (F4 and F5) it does nothing. Is there a different way to adjust brightness, or how do I get these buttons to work! I have tried hitting it while holding down the FN key as well, and it does nothing, please help!

As you boot, at the grub menu, type e to edit the boot options.
On the linux (kernel) line, near quiet splash add nolapic
quiet splash nolapic
If that works, we can add it to the default boot options. Edit /etc/default/grub
# command line
sudo -e /etc/default/grub
#graphical
gksudo gedit /etc/default/grub
Change the GRUB_CMDLINE_LINUX_DEFAULT to read
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nolapic"
Save your edit, then update grub
sudo update-grub
If nolapic does not work, try acpi_backlight=vendor

"nolapic" did not work. "acpi_backlight=vendor" works! Thx! – Tarnay Kálmán Apr 08 '12 at 23:40
