Not any more, that's the whole prolem!!
The *whole* of my xorg.conf file as generate by Ubuntu 8.10
Identifier "Configured Video Device"
Identifier "Configured Monitor"
Identifier "Default Screen"
Monitor "Configured Monitor"
Device "Configured Video Device"
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.
