HP Pavilion zv5000: I am able to boot up to Ubuntu 12.04 LTS 64-bit using Live CD, but I get a "GPU lockup" message when I boot from my Ubuntu 12.04 installation on my hard drive. Ubuntu installed easily, but it will not boot up.
I know there is a problem with my Nvidia geForce4 440 Go GPU because I can not load the driver for it in Windows XP (if I do the system crashes). In Windows, I am able to use the computer at 1024 X 768 resolution via the VGA.SYS system file (that is the only way it will work). Why does my laptop run on Ubuntu Live CD? And why won't it boot from my hard drive installation (GPU lockup)?
