Hi Durk,
The configurable pipeline has nothing to do with multiscreen. It is used to
configure the way any viewport is rendered. The windows are setup using the
camera group, the same than with the classic way.
I don't know for Linux, but for Windows, the memory of each card doesn't add
up. All resources are allocated on each card, and if not in sli mode, one card
blit the other display to the other card. When in sli mode, frames are
interleaved. So it's likely that your crash come from memory exhaution.
Another thing is that shadows and lights are still broken/misplaced in dual
screen, the only mode i can test.
Regards,
-Fred

Just following up on an old thread. Last weekend, I got my new videocards (two
GeForce GTX 660s) with 2Gigs of video ram. Running the Rembrandt code on a
single windowed instance of FlightGear works nicely and out the box, but when I
try to run the code with a triple screen set up, I get a segmentation fault.
I've been reading up on the project Rembrandt wiki page, and I understand that
you can set up a configurable pipeline, but it's not clear whether that is
necessary or not. Additionally, while I understand the syntax, I have some
trouble estimating, which parameters to fill in the sample code. Do you perhaps
have a working example, since I've been hoping to get this to work before
FSWeekend?
Running on linux, with the X-Server in xinerama mode. I've placed a copy of my
camera-view.xml file in my public dropbox folder:

Many thanks in advance!
Cheers,
Durk
