[ale] FC3/Xorg Monitor question

[John Mills]

ALErs -

I have an FC3 system -- long overdue for upgrade, I know -- on which I 
want use a Samsung LCD monitor with a native resolution of 1440x900. This 
does not seem to be one of the choices in my configuration, or at least 
not from the GUI to control display settings: even selecting the monitor 
as "Generic LCD 1440x900" does not offer that resolution.

How can I configure my 'Xorg' X-Windows to support the monitor's native 
1440x900 resolution?

TIA.
