Hey guys, I'm having a bit of trouble getting triple monitors working on my system. The two plugged into the graphics card (radeon x300) work fine, but the one plugged into onboard graphics (geforce 6150SE) refuses to appear in xrandr. I figure I need to make a /etc/X11/xorg.conf.d/10-monitor.conf file but I'm confused about how to do it with separate cards. I find the wiki instructions that I can find confusing, as I've never had to deal with xorg files before (has always autoconfigured for me no problems).

I just can't seem to understand how to write the 10-monitor.conf file. I was wondering if anyone could give me a hand?
Also, the third monitor to be connected via onboard VGA is also 1280x1024 and will be left of the other two.
If I am not mistaken I thought you could only use one or other other, meaning onboard or graphics card.

Depends on the motherboard. This one allows you to enable the onboard graphics only when no external card is found, or always enable. The PCI-E card initialises first, if that helps.
EDIT: Also I can confirm that it can run both cards (all three monitors) at the same time by switching to initialise the onboard card first, however that makes some weird stuff happen so I switched it back. And also the nouveau driver is shown in lsmod, and gets detected in the boot message logs.

If anyone even has a xorg.conf that shows how to configure for 2 graphics cards with different drivers, that would help too.
