I have installed clean Ubuntu with gnome desktop environment (This was installer only with gnome so no unity and not upgraded from unity to gnome). And I'm very happy with it, but there is a system massage that tells me there is an update to 13.04.
Ok thats cool, but if I press upgrade will it upgrade everything OK, and keep my gnome? Or it will upgrade and install Unity and mix up my whole installation.
I've read that its not very good to have both gnome and unity or to "upgrade" from one to another. It's always better to just clean install the one you like.
So my question is: If I upgrade my Ubuntu 12.10-gnome will it keep it (the gnome) or it will install unity and its going to be a big mess...?
