I know that Ubuntu 12.04 allows for specifying Unity 2D or 3D at login. Using Unity 2D when playing 3D games is supposed to make things work faster. Does this also apply to Ubuntu 13.04? If so, how can I get the Unity 2D desktop on my Raring Ringtail?
I am using an AMD 6670 graphics card with 1GB RAM and Catalyst 13.4 proprietary driver. I am running Ubuntu 13.04 64-bit.
