Problem Driving Two ATI Graphics Cards
I want to drive two ATI FirePro V4800 graphics cards in parallel (none of that Crossfire). The aticonfig --list-adapters gives

    * 0. 06:00.0 ATI FirePro (FireGL) Graphics Adapter
      1. 05:00.0 ATI FirePro (FireGL) Graphics Adapter
      2. 04:00.0 ATI FirePro (FireGL) Graphics Adapter

Which is good.

But the GUI "ATI Catalyst Control Center" still shows the not-default adapter as 

    -. [Unknown Display] Unknown adapter

This despite all their lshw saying:

    configuration: driver=fglrx_pci latency=0
