When I boot from the live USB, after selecting "Try Ubuntu ..." all graphics are interlaced, shifted to the right, duplicated and distorted -- Even the terminal when I access it by pressing CTRLALTF5.
Unity is also disabled. why would you call that a problem, some might say
lspci | grep -i VGA states
