If that is the case then I would definitely install Ubuntu via the alternate install CD. From what you have described it seems that Unity, Gnome 3, and KDE are having a problem with your system and the default nouveau driver. I don't know why this would be, since my nvidia 8400 GS has never caused a problem;
but as I said I have not used Unity. I install Lubuntu from the alternate install CD.
So go ahead and install Ubuntu 12.04 from the alternate install CD. Then see if you can boot to the Unity desktop and install the nvidia-current driver. If the system freezes after you boot to the desktop after the install, then reboot to the recovery mode and install the nvidia driver from recovery mode:
Code:
sudo apt-get update
sudo apt-get install nvidia-current nvidia-settings mesa-utils
Then reboot and open a terminal and run:
Code:
sudo nvidia-xconfig
This will enable the nvidia driver. If the system hangs when you reboot to the desktop after installing the nvidia driver, then reboot to recovery mode again and run the
sudo nvidia-xconfig command from recovery mode.
Then reboot to the desktop and check to see if the nvidia driver is running:
Code:
glxinfo | grep -i render
It should report
direct rendering: Yes, and something like this:
Code:
tom@desktop:/data$ glxinfo | grep -i render
direct rendering: Yes
