broken graphics after update in 12.04

view story

http://askubuntu.com – Hello before I start I want to make clear that I didn't upgraded anything, I was in 12.04 since it was out and I just did the updates that showed up since last Xmas (the pc is in my parents home and just returned) So no I didn't update to 12.10, this is what make it pretty weird here. To begin with the system is: AMD Athlon II x2 255 2gb ddr3 1333 gigabyte ati 4650 OC Hitachi deskstar 500GB split in 2 for windows and ubuntu So as I said I did some updates that have piled up since I last used this computer and then restarted as the update manager suggested Now I can't get in GUI it starts (HowTos)
