Switch between Intel nVidia in XBMCBuntu?

Hi,

Can anyone point me in the right direction? I have installed XBMCBuntu with a nVidia card installed. Now I have removed the card since basically the Intel HD2500 will suffice for this setup. The latest XBMCBuntu installation is suited for both nVidia and Intel graphics. But how can I configure it to work after removing the nVidia card? XBMC will not start because it's still expecting the nVidia card.
I know my way around the Linux command prompt, but lack the Xorg knowledge.
