      I use a distribution Ubuntu Edgy-Eft (6.10). The graphical chipset is
      an 855GM Intel and the installed driver is the i810. I have a curious
      behaviour wrt the extra VGA output.

      - The builtin LCD displays a very good screen.
      - With Fn+F8 the display is switched to the extra VGA output and gives
      a very good screen on a CRT or a Videoprojector.
      -With Fn+F8, another time, the screen is displayed simultaneously on
      the builtin LCD (very good screen) and the external CRT giving a
      vibrating image which looks like a frequency problem.

      Someone having an idea ?

      It is very difficult to do a presentation with a videoprojector but
      without a visual feedback on the builtin LCD.

      PS: I have tried to configure xorg.conf as it has to manage a dualhead
      card. No change. Setting-up a clone display freezes the Xorg server.

        I'm using Suse 9.3 on a Dell Latitude D400. It took a while (and some
        Xserver patches) to get dual-head working but it's happy now.

        I'll send you my xorg.conf off-list.
