Title:
  desktop cd fails to start gdm with hp nc6400 (widescreen, ati-based
  laptop)

Status in X.Org X server:
  Incomplete
Status in “xorg” package in Ubuntu:
  Fix Released

Bug description:
  Binary package hint: xorg

  The feisty beta desktop cd for amd64 boots ok on my nc6400, but gdm
  fails to start. The error log suggests that xorg found the ati video
  card, but couldn't find a valid mode. If I remove /etc/X11/xorg.conf
  entirely, xorg still can't find a usable mode. If I hand-edit the
  xorg.conf to add some modelines, I can get 1024x768 to work.

  Here are some details that may help:

  The ddcinfo seems off: this is definitely an lcd, not a crt. The input
  is digital, I'd think, and the dpms is probably wrong too. The native
  lcd resolution, 1280x800, isn't listed in the modes.

  If I can provide any other info, please let me know.
