The one remaining video issue is that I can't get the native video resolution that I want, the card supports the 1600x1200 that I want and so does the display but I can't get it to actually do it. The remote desktop via gdm is at 1600x1200 but when I fire up a local desktop I get only 1024x768. I've put the 1600x1200 resolutions as my first choice in the xorg.conf file, what is limiting it to less?
At a wild guess (I am no expert on X configuration) there is something wrong with your modeline for 1600X1200, probably the timings defined here put it outside the maximum values as defined by the "Monitor" section, either that or the values in the monitor section are not correct.
My Screen section is as follows:-
Section "Screen" Identifier "Screen 1" Device "GL1000" Monitor "LGFlatron" DefaultDepth 24
Subsection "Display" Depth 8 Modes "1600x1200" "1280x1024" "1024x768" ViewPort 0 0 EndSubsection Subsection "Display" Depth 16 Modes "1600x1200" "1280x1024" "1024x768" ViewPort 0 0 EndSubsection Subsection "Display" Depth 24 Modes "1600x1200" "1280x1024" "1024x768" ViewPort 0 0 EndSubsection EndSection
So, as I see it, there aren't any timings defined there. This is as generated by using xorgconfig so I assume the syntax is correct.
The way I understand it the "Monitor" section provides the absolute limits as to what your display hardware is capable of and then each modeline defines the specific timings for each resolution. If one of your modelines falls outside what is defined in the "Monitor" section then X will not use that resolution.
I've always seen these modelines as a bit of a black art, but I'd suggest you get the true specification for your display and then use something like http://xtiming.sourceforge.net/cgi-bin/xtiming.pl to generate the correct modeline.
The display specifications are from the monitor manual so are presumably correct.
