Hi, i solved this by firstly installing xbacklight. Then i placed acpi_backlight=vendor at the end of every line beginning with linux in my grub.cfg located at /boot/grub/grub.cfg using gedit.

Then i created an xbacklight.desktop file to initiate my desired backlight levels at bootup

hope this helps

i'm not sure what version of Ubuntu you are using, if 12.04 just go to system settings -->open "brightness and lock" and change brightness from there, see screen shot.

Wow, thank you very much Dwight! I never saw the scroll bar , its hard to see it. They should change the color to make it appear more. Thanks again!
