Help on setting up new graphics card driver -- Radeon HD 4870

[dat789]

$ lsb_release -all

At the moment of this writing, my xorg.conf (/etc/X11/xorg.conf) is empty.

Referring to the image above, I have previously activated the first item -- ATI/AMD proprietary FGLRX graphics driver (post-release updates) -- and after rebooting my screen shows a message that says "No input signal... out of range" or something similar to that effect. I had no choice but to reinstall Ubuntu. 4 times already.

I am using a VGA input LCD screen.
Screen resolution is, I believe, small -- fonts, images appear fairly large on a 17" screen.

Question is how to update the graphic card so that Ubuntu takes advantage of every aspect of the graphics card? It is now a fresh install. If you need any more info, I'll be happy to provide.

Any help appreciated. Thanks!

Have you activated the bottom one? As the bottom one is the supported one.

No, I have not.
I have, however, activated the one on top (first item) before and after rebooting my screen is not displaying anything -- Signal out of range.

I'll try the bottom one later today.

How about Catalyst?

If the bottom works for you it will install CCC.
