At my bike shop, I'm currently setting up a multi-seat Linux system,

I've got 2 NVidia cards up, and am looking to plug in another 3 Matrox
cards (I only have PCIe slots left, and they're about the only ones to
make PCIe 1x cards) to give me 5 seats.
Think this might make an interesting presentation when I'm done ?
3 seats are for Point of Sale, and 2 seats are for displaying motorcycle
videos, but when the salespeeople need to show the customer a part or
something, instead of bringing them around behind the counter, they just
switch the KVM to feed from an SVGA splitter so it replicates their
screen onto the other one.
This is like an extension of the presentation I gave a couple years ago
on Xinerama.
I think this would be a great topic for KPLUG. Your application is a bit
more than the casual user would need, but I can see the following scenario:
A user has a powerful machine that is mostly underutilized. One member
of the family (think Lan's son) wants/needs to run some other OS. The
main user runs Linux. Using a single computer with two displays, two
keyboards and two mice, both can compute away with only one PC. I have
also noticed that quite a few video cards provide both a VGA (analog)
output and a DVI-x (can be digital or analog depending on manufacturer)
that have separate CRT controllers, allowing you to drive two monitors
with one card. Both Nvidia and ATI support split operation on the CRTCs.
If you were to use such a card you would need only three cards, not
five. For example, my Nvidia MX440 can provide separate outputs to the
monitor and the TV set with both operating independently.
I think a stripped down demo version using only two displays would make
a good presentation. I have a spare computer you could borrow. I don't
have a video card with DVI output (or a monitor with DVI input, for that
matter) so you would have to borrow those from elsewhere.
