Public bug reported:
Fresh install of 11.10 amd64 on a machine with a dual head nVidia card
(shown by lspci as "nVidia Corporation G92 [GeForce GTS 250] rev a2")
with twin DVI outputs and a primary 30" monitor and secondary 23"
monitor, both connected via DVI. After 11.10 install completed, the
right-hand 23" monitor remains blank and in power save, although when I
open System Settings / Displays, both monitors appear there with the
initial display configuration showing as mirrored displays at 1152x864
resolution. Un-mirroring the displays and setting each display to its
native resolution and orientation still has the LH monitor blank. I
think the problem is that the 23" monitor is being incorrectly detected
as being connected via HDMI, as when I run xrandr in a terminal it shows

The video card does not have any HDMI output at all, just the two DVI
outputs.
