This question already has an answer here:
I have an AMD Raedon 6770 graphics card in my computer, and for some reason I'm unable to get Ubuntu 13.10 to read it. I had another copy of 13.10 on my desktop, but when I tried to install the .run file for the card from the terminal, it corrupted something within my operating system and I could no longer get Ubuntu to boot. I'm fairly new to this operating system, but am beginning to grasp the concept pretty fast. Is there anyway to add a library of screen resolutions? I really need something with a 16:9 ratio for my Emerson TV screen which I'm using as my monitor, and currently only 4:3 is available (linked tv to computer through a monitor cable).
I've also tried to run a few xrandr commands without any success. Any suggestions would be greatly appreciated!
