This bug effects me as well. Let alone installation, I can't even use
Live CD due to this bug. Ubuntu is completely unusable. See more in this
thread (with screen shots). SuSe Linux boots and Works just fine but
Ubuntu hangs all the time.

My laptop has GTX880M 8GB GPU. Obviously this is an Nvidia related bug
and no importance is given to fix it. Shame for Linux community not to
support a top of the line graphics card in 2015.
