[Dylan Justice <769366@xxxxxxxxxxxxxxxxxx>]

The bug is that when no EDID information is available, the default
resolution options top out at 1024x768.  This is not usable on most
modern systems.  It would be very easy to provide a list of standard 4:3
and 16:9 resolutions so that if it can't be autoconfigured, a user can
at least use the gui to choose something *close* without having to
generate an Xorg.conf.

To address the minimum criteria for a complete bug report, I reiterate
from my initial post:

1) I created a system that used a DP->DVI adapter.  No EDID info was generated.
2) I expected to be presented with a list of common resolutions in the gui.
3) The list of default resolutions topped out at 1024x768.

Title:
  Monitor prefs: poor resolution options when EDID fails

Status in “gnome-control-center” package in Ubuntu:
  Incomplete

Bug description:
  Binary package hint: gnome-control-center

  If EDID/DDC fails, the resolution options are too restrictive; an
  exhaustive list of resolutions should be available.

  Use case: I run my third monitor through a DisplayPort-->DVI adapter,
  so no EDID information is returned.  I cannot find any way to set the
  correct resolution short of generating an xorg.conf.
