HP ProBook 4515s/Mint 13 Mate
After installation in Mint and HP brightness is maximum, but display is so dark. Even less brightness dont work.
Older Ubuntu and Mint works ok.
First experiment was Ubuntu 12.04, and same problem.
Different codes dont work, because I am not root. How to be root?
Is there any solution?
gksudo gedit /etc/default/grub
dont lead anywhere
