Question Games defaulting to TV-Out...?

Truly weird bug.. okay, here's my current setup, then I'll describe the problem:

Debian Linux 2.6.0, Athlon XP 2200+, 1GB DDR266 RAM, GeForce FX 5600 256MB card with driver version 5336 (the latest one released a few days ago).

The problem is that when I try to do play games, anything that's fullscreen and 3D, the card automatically cuts the signal to my monitor and shunts it off to my TV. So as soon as I load up, say, the Unreal Tournament 2003 Demo, it loads up the little splash screen, and then switches the signal over to the TV, shutting down my monitor. AS soon as I kill UT2003, the signal automatically comes back to the main monitor.

I had previously set up my XF86Config-4 to be able to use TV-Out and the monitor, and switch between them by pressing Ctrl - + or Ctrl - -, and that was working fine, but the moment I turn on a game, it goes over to the TV. Strange. Here's the relevant parts of my XF86Config-4:

Heh.. I've been thinking of getting myself a wireless mouse and keyboard anyway.. but since I often game while my gf watches TV (and vice versa), I would really like my 3D games to show up on my computer monitor instead of the TV.

Another odd thing I've noticed (and I suppose this is more of an Nvidia thing than a Linux thing): I rebooted the computer while the TV was on, and the card showed me the whole bootup process (even the part where it checks the RAM which is long before Linux even has a chance to boot) on the TV. After it has booted up completely, once it switches into X, the twinned display on the TV goes away.. until I switch to it or I turn on a game. :P

I'm guessing that if I change my XF86 Config so I have to manually edit it and restart my X server to switch between TV and monitor, then the problem would probably go aay (I'll try it, maybe it'll help diagnose the problem), but I would really like to not hae to do that, it's really handy to be able to switch my display over to my TV and back to my monitor with only a couple of keystrokes.

at which resolution do you play UT? perhaps it's 800x600, and X switches to the second metamode?

That was exactly it. I went in and changed the resolution in UT to 1024x768, and it propmptly switched itself back to my monitor.. so basically, when I do something that requires the lower resolution, it will switch to the first available metamode with that resolution. Didn't know it did that.

I took advantage of it, though, by adding a third metamode with 800x600 on my monitor and NULL on the TV, so that those games I have that force me to go to 800x600 can still be played on my monitor. Thanks for the help, y'all.
