Comment 13 for bug 528277

This is my experience,

Tested with alpha 3 and daily build (2 Mar)

Test1:
VGA only : I can hear de Ubuntu sound at the end, but no signal on screen.

Test2:
DVI only : I can hear de Ubuntu sound at the end, but no signal on screen.

Test3:
DVI only and "nomodeset" option at start up. (I can see the blue lines of plymouth) and finally appears one buggy screen with "yellow" horizontal bands.

After Pressing Ctrl+Alt+F1 and go back to Ctrl+Alt+F7 the desktop screen is ok but with wrong resolution. If I go to System > Preferences> Screen , it can't detect the right screen model and resolution.

$lspci |grep nVidia
01:00.0 VGA compatible controller: nVidia Corporation G73 [GeForce 7600 GS] (rev a1)

ASAP i will do the Casper debugging.
