Public bug reported:
just installed 7.10 rc on a lenovo R61
this laptop is known to ship with different graphic cards. this has:

after installation, the screen was blank, and I wasn't able to switch to
virtual consoles or reboot with the keyboard
I had to shutdown the hard way, boot with the install disk in rescue mode,
install ssh server just to start doing some tests
It happears the nv driver locked the screen.
then I found out I had to use nvidia-glx-new, installed it manually, and
now X works.
strangely enough, after starting and killing X with nvidia-glx-new
(Driver = nvidia), the nv driver worked correctly. but after a reboot
the same configuration locked the screen again.
then, I may suppose the nvidia driver does some initialization on the
hardware that enables the nv driver to work, but if the nv driver is run
after a reboot it isn't able to properly initialize the card.
I will post Xorg logs for the three cases.
I suggest the installer detects graphic cards that won't work, disable
automatic gdm startup and warn the user, or better suggests to install
the correct proprietary driver and does it if the user whishes.
a similar Xorg bug has already been filled for a Quadro FX 570M on Lenovo R61:
