Would it be possible to remove the need for "sudo dpkg-reconfigure
xserver-xorg" (for example by automating the process). Then, supposedly, 
one could just plug in a new graphics card and go on using his system. 
It feels a little funny to be able to do this with the motherboard but 
not with the graphics card.
