10:18 PM EDT 		Is it possible to mirror a X display across two different graphics cards? Namely I am looking into an external display adapter that there support says only works as a separate X display - http://support.plugable.com/plugable/topics/mirror_display_o...

Ideas/input?

Nvidia has something similar for their own cards which you can use in sli or separate mode the Nvidia drivers are far better.

I could be totally wrong though been a while since i mucked around with graphics cards.

They both have FOSS drivers in the kernel though so I'm hoping I might be able to figure something out...
