two cards, one monitor linux desktop

[being]

Hey.


I have two cards and one monitor. I want to be "stuck" on one screen only (so my mouse cursor wouldn't slide on the other screen), so I made two different xorg.conf files and made one initialize one card and second the second card. I used gdm for my desktop and xinit -config xorg2.conf -- :1 to "activate" the second card.

But the problem is, that when I run poclbm.py it hangs till I ALT+CTRL+F9 to activate the second cards screen :1
So I'm only able to use the main desktop card with this setup.

Basically what I need is two active cards, but only one "active" screen.

Any advice to make it function?


Thanks.
