The standard ones currently as I have not been able yet to get it stable enough to find and install the other ones.
Basically there are the standard drivers then the fglrx and then the fglrx with updates drivers available ... I changed the option to use the fglrx driver through the gui and then back to the standard hoping this would fix the problem. The result is better but still no icons on the desktop or Launchpad... I attempted to install unity and ... I think it was ccmz or something like that and I got an error regarding this on a reboot that it had troubles loading.. so I have been trying to uninstall this - however lost the page where the commands were written so I am still searching
