I use Ubuntu Reconstructor, and I use it incredibly well. But a person is going to have to pay me money for my advice.
omgz, teaser.
Ubuntu Feisty can allow the insertion of video drivers, and they are activated after logging out and logging back in.
And they said you couldn't use video drivers. pah.
Ubuntu Gusty really can't do that (probably can), and I haven't found out how yet. I'm not too concerned because of the Screens and Graphics option.
But xorg.conf does get re-implemented after a re-login for both OSs, which is best with a VESA-type setup.
