After boot, could you switch to a text console (ctrl+alt+F1) and log in, then do the following:
sudo su vbetool vbestate save >/tmp/vbestate vbetool vbestate restore </tmp/vbestate
and then press ctrl+alt+F7 to switch back to X. Does this work?
Could you let us know which video driver (nv or nvidia) you're using?
