Hi Mackenzie,

I don't know how the code for auto-detection of monitors works but I
have used the above linked procedure (also described in the X wiki
pages) to work around it.  As I perform some more searches I see quite
a few items on and with
problems auto-detecting monitors.  Another complication I came across
just this week when I installed 10.04 on a laptop was that it required
the use of binary drivers for the video card and wifi adapater to
allow suspend and resume to work.  In fact says "Monitor detection is
one of Ubuntu/Xorg's most major problems."  My experience sponsoring
several school computer labs in San Francisco using donated hardware
seems to support this claim.  X/MonitorDetection gives a great
description of the problem from the perspective with some
insight into why the problem exists.  Unfortunately that page was
written in 2007 and has not been updated.

Thank you for the link to
you provided earlier in this thread.  The X wiki pages have some great
information.  To answer your question I suspect it would best be asked
on IRC or the Ubuntu X mail list linked from the ~ubuntu-x-swat
launchpad team page.
