I have been trying to understand why Xorg chooses an odd resolution
(1152x864) on my system rather than the monitor's native 1600x1200.

Well I can see *where* it does it, here is the relevant section of my
Xorg.0.log file:-

[snip contents of Xorg.0.log]

How do I tell the system to default to 1600x1200?

There should be another line labeled Modes, the first resolution in
that line is the system resolution used. For example:
Section "Screen"
DefaultDepth 24
SubSection "Display"
Depth 24
Virtual 1920 1200
Modes "1280x1024" "1280x960" "1152x864"
"1024x768" "832x624" "800x600" "720x400

This makes 1280x1024 the default resolution.

Not any more, that's the whole prolem!!

The *whole* of my xorg.conf file as generate by Ubuntu 8.10
installation is:-

Section "Device"
Identifier "Configured Video Device"
EndSection

Section "Monitor"
Identifier "Configured Monitor"
EndSection

Section "Screen"
Identifier "Default Screen"
Monitor "Configured Monitor"
Device "Configured Video Device"
EndSection

Xorg now generates the actual settings 'on the fly' each time it's
started up. If it gets the right resolution then that's fine but it's
a bit of a nuisance (as in my case) if it gets it wrong.
