After installing the driver for the video card ATI Radeon HD 3870, I can not run Ubuntu (just a purple screen and all). Tried to go to recovery mode as root and write "apt-get purge fglrx*", but nothing happened. Then I decided to go into failsafe mode, but nothing (writes "clean some blocks" and all).
-Ubuntu 12.04 LTS (kernel 3.3.6) -ATI Radeon HD 3870
P.S. Sorry if I write with mistakes. I am Russian, and understand very little English, so I used Google
