Ubuntu 12.04.1
Sony Vaio VPCSB11FX
AMD Radeon HD 6740M

The open source drivers from xorg don't work with my graphics card, and neither do the fglrx drivers from Jockey. AMD Catalyst worked a few weeks ago on linux kernel 3.2.0-29, but doesn't work with 3.2.0-29. It won't load the desktop, and I have to use my computer through the terminal.

How do I get my graphics card to work?
