Comment 41 for bug 488720

I've just upgraded to this kernel, and I don't believe it's fixed the issue. Here are the details, following a dist-upgrade with that PPA:

Reboot - GDM login screen displays, login bongos play
Press return, to select default user - Screen blanks, a few coloured blocks appear briefly, GDM reappears, login bongos play again.
Press return, to select default user - password box appears, accepts password, login completes.
Suspend laptop - screen fades to black, laptop powers down, power LED pulsates indicating suspend mode
Press power, to resume - laptop powers up, screen is blank black, GDM login bongos play
Switch VT twice - After a couple of attempts GDM screen is displayed,

alex@martha:~$ uname -a

alex@martha:~$ aptitude show nvidia-current | grep Ver

Hope that helps
