Quad Monitors

I have two systems that I custom built to drive quad high res monitors (1080P ). Both will drive all four under Windows ( Vista & 7 ), and both will drive ONLY TWO under Linux SUSE, though both cards are recognized. It seems to drive only one card. Any thoughts on this… suggestions?

You need to give us more details on the hardware, start with running from terminal as su -(from both machines)

lspci -nnk

copy and paste the output here.

I’ll do that this evening… At the moment I can’t. Thanks!
