I having problem with ubuntu 12.4.I am using win 7, I set up it and after that I open my computer , it doesn't work , all is black screen and nothing else. I put my Win 7 CD to set up again and I have been waiting to see what's going on with my laptop? haven't any result. Could you help me to solve this problem? I am really need to fix because I used my laptop for studying.
I had the same problem. what i did was right click and select change desktop background, all settings, additional drivers, update and restart. at the log in, click the icon and select Ubuntu 2D, and log in.
