It appears the Nvidia driver is somehow not installed properly. Xorg is using software rendering instead of the Nvidia driver on this machine. That's also why it doesn't support the HDMI connector.

Try uninstalling and reinstalling the Nvidia driver. Also check to see if you have any custom Xorg config files that might cause the Nvidia driver to not get loaded.
