Comment 5 for bug 38433

Just wanted to add that I've had the same problem with both the Live CD (flight 6) and the install CD (Beta 2). My machine has both an integrated Intel 82865G graphics card and a PCI nVidia GeForce FX 5200. The bios is set to use the nvidia card as the primary display (my bios won't support actually disabling the integrated card). On installation the xserver detects the integrated card and creates an entry in the xorg.conf file for it, but not for the nvidia card. On the first boot the xserver fails to start (since there's no display attached to the card it is using). Manually adding a section for my real video card to xorg.conf fixes the problem. However, even though I'm running on the nvidia card, running

dpkg-reconfigure -phigh xserver-xorg

again only detects the integrated card.

Hope these details help you track it down.
