Xorg Multi-GPU Display issue [Solved]

I'm a big noob when it's about Xorg and the configuration but anyway, let's get to the point.

I'm using two GPU's. One is a ATI HD4870 and the other one is a Intel HD4600. I have two DVI displays connected to the HD4870 and one VGA display to the iGPU. Problem is Xorg is only willing to use one GPU. All open source drivers are installed correctly and I'm using latest drivers, Xorg, etc.

I have three files in xorg.conf.d
20-intel.conf
20-radeon.conf
90-monitor.conf

I'd love to get all three monitors working, they're all 1280x1024 by the way.
Thanks in advance!

Your system uses a Hybrid Graphics setup, check the PRIME wiki page.

Thanks, I'll have a look and post if I run in to problems.

Solved by plugging 2nd screen in iGPU, using iGPU as main device and adding the other monitor on boot via system.d
