you will probably need to set xorg for two separate displays, and
one of these can be 3D accelerated, I usually start pd with Gem from the
display with the projector, and control it with another pd started on the
other display. This has worked well with 4 screens from 2 NVIDIA cards
uswing debian, I guess it would be also ok with an intel chipset, as it
does not rely on twinview or any other fancy graphics stuff. Alternatively
I believe Gem can open a gemwin on a different display to the one pd was
started on, check the list archives as I have not tried this.Ah, that sounds right - do you know achieve 3D rendering on "one" of the displays? As mentioned, my xorg.conf is set as a big virtual desktop shared between two screens..:
exact details will depend very much on the graphics card and driver,
but you should aim for the projector display to be the first, or
primary, display, possibly use xorg.conf to turn on direct rendering
for that one and off for the other. With NVIDIA most of this can be
done with the driver GUI. Then either start pd from that display or
give gemwin the appropriate message - I forget what it is but it was
on this list a few weeks ago.
