Also affecting me. The following points may be of interest:
1. Graphics: NVIDIA GeForce G210M with 512MB DDR Dedicated Memory.
2. Machine: Lenovo G550 NTDF3UK (Laptop)
3. Previously I upgraded (on the standard driver) from 11.10 to 12.04 and this issue did not occur.
4. I erased and reinstalled my entire OS (for fun) and then the issue started. I have tried with the default driver and also with the proprietary driver in 'Additional Drivers' and both exhibit the same issue.
5. If I keep rebooting my machine it eventually recovers and logs me into the desktop. Sometime it logs me in first time, other times it takes around2-3 reboots and then it is fine again until the next time.
6. I've attached my output from SysInfo in case anything in there is of interest (GM_SysInfo).
