Hi there! I had some problems with my ATI Radeon GPU overheating and I had to reinstall the drivers. Since I'm a newbie, obviously, something gone wrong and my beautiful Gnome 3 desktop has turn into beastly-gnome-2. Now the GPU fan works just fine but I also want to get back my old desktop. I already tried this and it's not working. I've tried googling my problem but I didn't find anything useful. Are there any chances to "reinstall/reset" it?
