I tried to figure out the inner workings of the intel_extreme driver, but
apperently I lack some deeper understanding.

My question is, what needs to be done to enable a screen resolution of
1920x1200?


While I can't be much help on this either, I'm also interested in the
end result. I was considering taking my 24" Samsung LCD with me to
LinuxWorld, but the intel_extreme driver only displays 1600x1200 on it
(VGA mode), and it looks kinda stretched as a result.

I'm guessing that at a minimum the modelines need to be added to
support the various resolutions if they're not already there.
I don't know all the details about the intel_extreme driver, but I do know that, like the S3 driver, it uses the common accelerant code to build the mode list; and the mode table in the common accelerant does have an entry for 1920x1200. Thus, my guess is that either the EDID code in the common accelerant is ignoring the 1920x1200 resolution, or there is something in the intel_extreme driver which is causing that resolution to be excluded. Axel can probably answer that question.
Is resolution 1680x1050 enabled? It is also shown as an "additional" video mode in the EDID info of the syslog. 

Best regards,
Gerald
