dual displays

i have two graphics cards, a 6800 and a tnt2.
how should i setup the x config so that the tnt2 displays my kde desktop on my 15"lcd and the 6800 runs games on my 19"crt?[/code]

Nice question. I've got a similar situation with a radeon with dual vga. I'm using a 17"crt as primary screen and a small 14" crt as secondary. Gentoo sets the 14" screen as the primary one. How to change this? It happens in framebuffer and X.

Its real easy to do, you just need to mess around with getting xinerama or twinview working in your xorg.conf.
