[Bug 470422] Re: [Q45] 1600x1200 resolution is not available on the 2nd monitor (it was on ubuntu 9.04)

[Geir Ove Myhr]

Good, then the size of the EDID block makes sense. Not sure if there is
something else which is non-standard with the EDID information. I guess
it has to be something, since the 1600x1200 mode is not listed in
Xorg.0.log after the EDID for HDMI1.

Since it does not make a difference for the resolution and we want to
keep the test case as simple as possible, we would like to have only the
HDMI/DVI connected when troubleshooting this. Also please move away
/etc/X11/xorg.conf so that we have a standard configuration (it should
not make any difference for the behaviour). Could you provide `xrandr
--verbose`, `dmesg` and Xorg.0.log for that case?

We would also like the same logs for the UMS case (i.e. nomodeset boot
option). Even though it does not make any difference in behaviour, there
may be differences in the logs.

If you have access to a computer (with intel graphics chipset) with DVI
output it would also be a useful data point to know what happens if you
connect the monitor to that. You don't need to install ubuntu on that
computer, a LiveCD/LiveUSB test would do. Still, the logs for that case
would be interesting (can be copied off the LiveCD session).
