Hi, I think I just got bitten by this same bug. Runing ubuntu 14.10. I installed nvidia drivers on Dell Vostro notebook. After this, any attempt to log in to Xwindows results in a loop and returns to the login window.
I tried following the suggestion here and booting with "nogpumanager". It seems to have broken something else and now the machine gets stuck in booting, even after removing it again.
