I have an LCD monitor with both VGA and DVI connectors on it, and a video card to match (both connectors). If I want to switch from the VGA (currently in use) to the DVI, do I need to do anything special other than switch wires? I didn't see anything in google that was helpful (though I may not have used a smashing search...).
Thanks.

If they're both the same output (i.e. not individual outputs, but just different media options) then I'd say yes. But if they are distinct outputs (say for a multi-monitor setup) then one may be display #1 and the other #2. If it's integrated video on your motherboard there may be options in your BIOS, but if it's an add-on card then maybe consult the manufacturer's website.

Like Chris said it does have to be the same output, but you will have to change in the monitor menu or input option whichever you want to use. DVI or VGA.
cheers

That seems to be true, but until I unplugged the VGA cable, nothing changed. The screen went black (no input, complete with the short "no video signal" message from the screen) until I reset the gdm. Then it recognized and used the DVI for output.
It works fine, but I'm not so sure about having both cables connected at the same time.
NVidia's tech person said that I should only use one cable per monitor, although having both connected won't hurt anything.
There is a setting that can be used in xorg.conf to tell X what order to use in scanning for a monitor, but I figured it's just easier to have one cable plugged in.
The difference in the video itself (DVI vs. VGA) is quite startling - visibly cleaner and crisper.
Thanks everyone!
