My computer boots to a black screen, what options do I have to fix it?
When my laptop is booting I can't see the menu, but grub is there, if I press enter it boots my first option, it's only showing the purple screen.
I'm pretty sure it's some video setting, but I don't know what to change.
My Configuration: UBUNTU 12.04 LTS LAPTOP ASUS N56VZ GEFORCE GT 550M
