http://ubuntuforums.org – Hey everyone, I'm a complete newbie to Linux. I don't have a clue about anything. However, I found Windows 8 revolting and so I installed Ubuntu 12.04 LTS as my primary OS. I wanted all those cool animations, so I installed CompizConfig Settings Manager. I activated the Desktop Cube and Animations. Since then, my PC freezes from time to time when I switch tabs within my browser or when I switch workspaces. The mouse continues to move, but none of the keyboard shorcuts work. Additionaly, when I boot into Unity 2D, everything works fine. Please, please help me out here. (Hardware)
