Hi, good to be back here after a while.
Facing a problem with Ubuntu 13.04 X64. Installed Gnome shell and created two accounts, on one Unity is default, on another gnome is default DE. Everything was working well with gnome 3.6, but after hearing that gnome for Ubuntu 13.04 can be upgraded to 3.8, did that.
Now, Unity DE is broken, and is acting illogically (like hangs, wallpaper /bar disappears etc. to name a few!). I installed gnome 3.8 from gnome 3 stable ppa.
What to do now? Should I revert back to 3.6 (don't know how to do that, if possible at all without uninstalling! [-o
