When I first got my laptop, Unity 3D worked fine. Then, suddenly, it stopped. Then, regardless of which desktop environment I chose, it booted Unity 2D. I tried installing my ATI/AMD graphics drivers, and only the non-post-release on installs. That doesn't even fix the issue.
Assuming it was an issue with Unity, I installed Gnome 3. To my surprise, the same issue occurred again! When I told it to boot Gnome, it went to Gnome Classic. Please help me! I would really like to have Ubuntu up and running on my laptop before I start college.
