I have a laptop that I installed Ubuntu 14.04 LTS on a little while back. I do not know the full specs, mainly because this laptop is five or six years old and was originally my dad's. I want to update my video card drivers for a better gaming experience, but after installing a crapload of stuff my computer now can't support even 1080p videos. My video card drivers, according to my dad, are AMD, but according to the specs, my drivers are Gallium. Please help me fix and update!
