i had the same problem if you have a external graphics card remove it and run it again and it will work.
i hope this will help a little
I have Backtrack on a USB 2.0 pen. I know it works as I have had it work on various PCs without Wireless Cards in my College. I am running Windows 8 but don't feel this is the problem as I have ran MacPup from the USB pen in the past. I have tried BackTrack5r3 both 64 and 32bit versions with both KDE and Gnome on my own PC and I receive the same message which doesn't affect other computers.
Marvel at the dodgy camera work ...

and yet I'm sure I have enough memory ...

If anyone can help I would be very grateful and apologies if this issue has already been addressed on here.
