I tried to get my card working in Ubuntu 12.04 using both the normal and experimental AMD drivers supplied by Ubuntu and the ones (.run files) downloaded from the AMD support site. When using the Ubuntu drivers, I get the "hardware not supported" logo in the bottom right corner. When installing the drivers from the website, a prompt will appear saying "Your graphics adapter is not supported" and then the installer will quit. I have the following Ubuntu approved Lenovo Desktop.
I'm a little confused as to why this machine is Ubuntu approved, but the graphics drivers aren't working. Any help in getting this fixed is appreciated.
