It looks like my real problem is going to be the dual monitors in SL3.
I guess the guidance I need is how to configure the dual head graphics
cards; what do you have to do to the Matrox cards, for example, to get
the dual heads working? This is a PCIe motherboard, so it looks like
I'd want the P650 if I need to trade in my PNY cards, since that's a
PCIE x16 dual DVI jobby. But if I get the driver from the Matrox site
(http://www.matrox.com/mga/support/drivers/latest/home.cfm) what do I
have to do to get the second head working? I can't see it in the SL3
docs, and SL4 has display configuration for the second monitor. The
nvidia driver actually works for the first head with the PNY card; it's
just not clear what's needed to get the second half working.
Thanks for the information--this thread has already cleared up some
questions for me.
