When you boot, edit your grub boot command and see what the vga= value is and try setting a different value. See here for different default values - http://www.pendrivelinux.com/vga-boo...en-resolution/
You could also try the nomodeset in the grub boot command and see if that works too. See here: http://www.backtrack-linux.org/forum...tml#post196026


I hope there's a fix soon with out having to do all the work arounds.
