I recently installed the gnome3 on my Ubuntu some 1-2 months ago, it was working nice, but today, i was trying a theme, and then after reverting, the gnome-shell is not working!, When i select gnome, it runs the ubuntu-2d or something mixed, there are no animations, but it is not ubuntu-2d,whatever it is... is no gnome!

Reinstalled gnome-shell, gnome-core, gnome-session! Now the "gnome" is not installing, it says that i do not have gnome-core installed, or when clicked "Install", It does nothing, but within half a second, switches between Installing.. and then back to "Free" .

What should i do?

Revise your software sources, make sure you have only oficial sources activated. Deactivate any "test" sources.

Then do apt-get remove--purge gnome-shell and install it again.

Also, make sure your display driver is installed and working properly, for the 3d to work, or else, gnome will log you into gnome-classic
