A well known problem with ATI on 12.10 ! I had the same problem with ATI 75xx card but disabling ATI proprietary driver and enabling X.org solved the problem. Anyway, I found this blog post here see if that could help.

You can always try disabling the ATI driver and activate the good old X.Org driver in Software Sources >> Additional driver >> Use X.Org driver

is there any specif error displayed ? Maybe some more details on what and how did you do it ? Try updating the system first and see if there is any update for X. –  Gufran Nov 7 '12 at 19:01

I have also ati radeon hd 5450 and after installing its driver I had the same problem as you. But I solved it after performing following command:

sudo apt-get install fglrx fglrx-amdcccle

Hope it will help you. For more information you can read following resource here - ATI Raden Ubuntu Quantal Installation Guide .
