Re: Viewport size in X

["Eric G . Miller" <egm2@jps.net>]

The virtual resolution will be as large as the largest screen resolution
listed (absent a Virtual line).  So, if you delete 1280x1024, leaving 
1024x768 800x600 640x480 you'll get a virtual screen size of 1024x768 no
matter what order the entries are in.  You can specify a larger virtual
than the display resolutions. So if you had 1024x768 as your largest
resolution and set Virtual to 1024x1536 you'll have a virtual resolution
that's as wide but twice as "tall" as your display.

Viewport is a different, but related thing.  It affects the initial
position of the display when the virtual resolution > display
resolution. Good for getting xdm|gdm login centered, I guess.
