View Full Version : [ubuntu] 1005pe brightness issues

April 6th, 2010, 10:57 PM
Hello all I am having that common random brightness issue problem with 9.10. Now before you post I am going to walk you through what I have done. I was following the original post here (http://ubuntuforums.org/showthread.php?t=1412922).

Here is what I did.

sudo gedit /etc/default/grub (but this file was empty)
Because it was empty I just added this line GRUB_CMDLINE_LINUX_DEFAULT="quiet acpi_osi=Linux"

I typed sudo update-grub2 command not found so I just ran update-grub

It still does not work. Thank you for your help.
