I have AMD Radeon HD 7670M graphic card. I want to know if theres any graphic driver present for Ubuntu 12.04 LTS?
Will Ubuntu 12.04 support this GPU on my laptop?
I've got AMD Radeon HD 7450M graphics card, and it worked perfectly well under Ubuntu 12.10 (64-bit). The same should probably apply to your card as well, which you can test by booting the said computer with a live CD/DVD/USB.
The only problem was the too much power consumption as it was actually a Hybrid Graphics card with an "Integrated" Intel graphics controller and a "Discreet" AMD/ATI one. I finally figured out how to turn off the latter when the computer is running on battery power. See: Error Creating .deb File of AMD Catalyst Driver
