This question already has an answer here:

I'm using an Ubuntu 12.04 LTS. Since, I discovered that there are other desktops on Ubuntu, rather than Unity, I installed Gnome 3.4.

But it freezes time by time, when I run many applications or little. Sometimes I can enter into no GUI with Ctrl+Alt+F1 and to restart my GDM, sometimes not, but my music is still playing in background, so I think kernel is not blocked, it's a GPU problem or maybe another. Please give me some advice or maybe you know what the problem is and the solution.

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

In my experience Gnome with Ubuntu is always unstable, unless if you are a pro. But if you are interested, you can use Ubuntu Gnome. It's the official Gnome flavor of Ubuntu and the site will be updated today for 13.04 Ubuntu release after few minutes.
