What's the smoothest way to change the monitor on a system? I've done this before and, aside from the initial cold boot (after unplugging the old monitor and plugging in the new one), it also took restarting X (gnome) several times to get the (new) monitor tuned correctly.

The "new" (actually a bit old) monitor is an Acer P191W d. It is a 19-inch, LCD flat-screen. Other specs:

Aspect Ratio 16:10, Native Resolution 1440 x 900 at 75 Hz Pixel Pitch 0.284 mm

Does anyone have an xorg.conf entry for this monitor and/or suggestions as to what a workable (or optimal) xorg.conf entry might be?

Thanks much.
