[NTLUG:Discuss] three headed linux box

[David Simmons]

Have an application where will need two screens for LCD projectors (that
will show different, static content)....want to have a third display for
normal computer control, etc.

If I run a dual-headed card such
as a nVidia 7800 series - I believe I can get TwinView to do what I
want/need....then if the motherboard has built-in video (that's also
nVidia chipset) - I'm interested as that will actually show up?  Can
I Twinview three displays on two different cards together? (the TwinView
section of the nvidia site is silent on this only discussing two
monitors).

Anyone have experience with this?

Thanks
