[Bug 379805] Re: virtual >2048 in xorg.conf causes blank white screen on login

[Geir Ove Myhr]

** Summary changed:

- virtual keyword in xorg.conf causes blank white screen on login
+ virtual >2048 in xorg.conf causes blank white screen on login

** Description changed:

  Binary package hint: xserver-xorg-video-intel
  
  I'm trying to configure the secondary output on this laptop for use with projectors (etc). 
  When I go through system / preferences / display, it tells me that the virtual keyword needs adding to my xorg.conf file and does it for me.
  When I reboot with "virtual" in xorg.conf and login, I get a blank white screen.
  If I use ctrl+alt+f1 to get a command line, edit xorg.conf to comment out the display subsection and then restart gdm, everything is works - except that of course the secondary output will only work as a mirror.
