3) What you expected to happen
To be able to migrate this lab of mini PC's to ubuntu, using a screen
resolution greater than 800x600
4) What happened instead
Spent 3 days attempting to work around issue with the ubuntu included tools, as
well as reviewed a portion of the large volume of discussion on this issue.
Loaded latest developer release and had to fall back to pre-ubuntu tools to
resolve the issue.
detailed discussion below
Problem statement: As widely discussed, ubuntu 8.1 and now testing on
9.04 is showing that if the "Mobile 915GM/GMS/910GML Express Graphics
Controller" (or it looks like any of the other i810 variants) that
Ubuntu completely fails to handle detection of the display adapter and
its configuration over the intel graphics chipset and fails to the safe
"vesa" setting... locking the user into a unresolvable 800x600 user
experience with the Ubuntu product.
I would propose that the current approach being taken to "make it
easier" for users to deal with video settings, has created a
configuration gap for systems on this chipset, and possibly other
configurations as well. Users must go "off the reserve" and hack their
configurations completely to resolve this.... and the current set of
wiki and community support content is a mess over the issue, with
pointers to hacks for the issue that is completely opposite the design
objectives of "making this easier".
Now, it appears that with the latest intel drivers, or with what is
present in the latest developer test release, everything is "working" at
the driver level... but the failed configuration in the xorg.conf is all
that is causing this to failsafe into the 800x600 resolution each time.
I found a workaround, and offer the following for consideration - when
the current approach being used by ubuntu to detect and configure
displays, that before falling to failsafe/low resolution, that an Xorg
-configure based attempt be offered to users to get beyond the current
display management limitations being seen (keep what you currently have,
and offer a workaround, possibly a seperate package that you point to
when this chipset is detected, or even something within this current
package to fall back to the older way of producing a working x
configuration).
Substituting this Xorg -configure output, and including monitor
information in my running xorg.conf resulted in a successful start into
a high resolution configuration.
While looping around and around with attempting to allow ubuntu to
configure this, and troubleshooting after; I did some reading up on the
X display server and found discussion on the Xorg -configure command...
I have iterated through the troubleshooting the startup and logs over
the last couple of days. After reading up enough I forced things with a
"sudo kill -9 [pid of running x display on 0];Xorg -configure"... this
allowed the command to run between the restart of the x server by the
gdm.
I then allowed the system to boot into the low resolution (800x600) and
copied the result of the Xorg command to my /etc/X11/xorg.conf settings.
I also found a good xorg.conf example for the type of monitor I have
attached, which I added to the configuration while attempting to
troubleshoot things as well, I appended this to the xorg.conf changes
made by the Xorg -configure.

while Xorg -configure works perfectly!
