Thanks, I will.  I've been updating every other day or so.  Aside from
occasional general unreproducible oddness, my main video problem now is
that in 1280x1024@60 (wide screen LCD), 5 or 10 pixes are cut off the
very top of the display.  No amount of auto-adjusting or fiddling with
the LCD has made a difference, and this mode worked as expected with the
same hardware under Dapper.  It looks odd, but I can live with it.

Does it exhibit the problem with "the other OS"?... if so, the LCD panel might not be aligned in the display housing. I've had a few monitors come that way, and had to open them up and shim the panel to get everything centered up.

No. This mode worked as expected with the same hardware under Dapper until I did a clean install of Gutsy 1 week ago. All 3 other PCs connected to that display via the KVM work as expected. The display works as expected in all other screen resolutions tried (1024x768 on the Optiplex, others on other OS/hardware combos).

FWIW, 1280x1024 is not a "Widescreen" resolution.  More likely
resolutions for a widescreen display would be 1680x1050 or 1280x800.
Both have a 16:10 aspect ratio.

You've got me there. I don't like widescreen monitors and got this one sort of by accident. It worked out well as the main use is VMware, so I can run the VMware console in 1280x1024, and run VMs inside that at 1024x786 and everything fits *really* well.


So all I know is that 1280x1024 suits my needs on that setup.


Your monitor should correctly report it's native resolution in its
EDID info.  This should be in your Xorg log.   If you don't specify
any resolution or timings, X might use the one reported by EDID.

It might. Then again, the circa early-mid 90's Compaq KVM in the mix muddies the waters considerably too. I don't see anything called "EDID" in /var/log/Xorg.0.log, and I know the LCD can display at higher resolution than the KVM can.


I should also mention that auto-adjust on the LCD is now goofy. More often than not if I try it it skews the display 3-4 inches to the right, which never happened that I recall before the Gutsy upgrade. If I fiddle around and auto-adjust on difference machine, I can eventually get it working, which then seems to stick.

In case it's useful, AFAICT the KVM is:
	Compaq Series 4114 KVM (spare part number 242696-001)
	AKA Apex EL-40DT
ftp://ftp.avocent.com/public/product-upgrades/Outlook/EL40-80DT/OL_DT_UG.pdf
	Supports analog: VGA, SVGA, XGA
