my story, Previously i was running 12.10 with kernal 3.5.0-25-generic, see my comment #54 so yesterday, i started downloading 13.04 but i never booted up from DVD, tried USB got partman error, all checksum of the ISo matched. Well then i finally made teh choice for switching to 12.04 and how my kernal is 3.2.0-40-generic and when i was chnaging fonts via gnome tweak took (i am on gnome classic) my system freezed and then it freezed when it was idle ans was running xscreensaver and screen never resumed, just blank screen.
