Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free, no registration required.

I have the amd a10-5800k apu, and later upgraded and added the amd hd 7770.

Whenever I play on games my fps is really low, so I did some digging and the graphics card in use seems to be the a1--5800k. When I install the graphics drivers, either through the software center or the terminal, I have to restart and I get a massive black bar all around my screen.

The temporary fix is to change the resolution, but that mucks up the aspect ratio. Is there a permanent fix? I have reinstalled ubuntu, but nothing I try seems to work. Sorry to waste time if this is a basic fix. Thanks for the help... assuming I get any :)
