I did a fresh install of ubuntu 12.10 x64 and installed AMD catalyst version 12.10. After rebooting the desktop is blank and unity doesn't load. When i uninstalled amd drivers, it was fine again.
I also tried to install drivers from "Additional Drivers" from "Software Sources" window, but result was same.
I am having a Radeon HD7770 graphics card and I am using 1920X1080 resolution.System is very slow with X.org drivers. I need help/suggestions to install proper drivers.
Thanks
