I've just set up BAMT on my 7 GPU rig and I get the following error as the OS is loading: "Failed to start the x server (your graphical interface). It is likely that it is not set up correctly. Would you like to view the X server output to diagnose the problem?"

Does anyone have any idea what this means? Could it be that I need to put dummy plugs in my GPUs?

System specs are as follows:

7 x Sapphire 7950 Dual-X
MSI Z77A-GD65 Mobo
2 x Corsair RM850 PSU
Intel Celeron G1610 CPU
8GB Corsair RAM
Powered Riser Cables
