changing primary desktop, no xorg.conf

I have two monitors hooked up to my nvidia geforce 4500, 23" monitor is a DVI and 19" is a VGA. Kubuntu seems to set my smaller one as the primary, which is annoying whenever I open full screen programs like games and they go to the 19".
After many thread searching I've seen that you can edit a xorg.conf file, however I seem to not have one.

Current X is capable of running without xorg.conf, though you can generate one.

See my qyestion here. I followed the instructions to generate one, then reached a point where I need to do more research before moving forward--I have a workaround, so the problem can wait till I have time to fix it if I break it while trying to fix it, if you know what I mean . . . .

You don't mention your distro. I found this at the Debian wiki. It provides a bit more background. Scroll down till you come to the section entitled What if I do not have an xorg config file?

Creating the xorg.conf worked it seems. I followed the second link.

After getting your xorg.conf it's a good idea to download the binary driver directly from nVidia (depending if your distro doesn't provide it).

The nvidia-settings utility allows me to dual monitor using xinerama (I think that's what it's called). It makes dual monitoring easy. But make sure to backup your xorg.conf before running nvidia-settings in case you need to revert changes.

Congrats, animedragon67.

Also, you can use the xrandr command.
