When booting, lightdm dumps to tty. No GUI interface works- this is after a fresh install of Ubuntu 12.04 where the GUI interface works when running off the USB.
I have an NVIDIA Corporation G98 [Quadro NVS 420] graphics card.
After I call startx from the terminal it still doesn't work. I get the following in the Xorg.0.log:
