My hardware:

Mobo: GA-Z68MA-D2H-B3
4g ram (2x2gb)
ATI 6950 video card

I installed the OS with unibeast, but now when I boot into the lion install (with the usb stick) all I get is a blank/grayish/whitish screen and I have a mouse cursor that I can move around but nothing else seems to happen.

Some notes about the install process:
1. I had to boot into single user mode the first time and copy ATI6000 and ATIRadeonX3000 Kexts into / from /Library/System/Extensions (i think this is where i got them).
2. I restarted and booted into the usb stick in single user mode again then exited and continued the install.

When booting into the lion partition from the usb stick I have tried:
arch=i386 -x -v
-s
GraphicsEnabler=No -x -v

All have given me no real success. I have tried a few PCIRootUID= with 0 and 1 but i don't recall what params I used with those.


Any suggestions?
 
99% sure this was a video card issue with my 6950. I used my 4870 and got past this pretty easily with a new install.
 
I have the same problem with my HIS 6970. (Had no problems to install Lion)
