Hi,

Happy new year! :)

...before I make my GENTOO box unaccessible to me ... ;)

For rendering with blenders new Cycles GPU based renderer
I want to setup my box as follows:

Rendering should be done with the GTX 560 Ti nvidia card and
the "normal" desktop (aka X11) should be handled via the
GT 430 nvidia card.

Both cards are already inserted into the box and seem to be
recognized since lspci reports:

    02:00.0 VGA compatible controller: nVidia Corporation GF108 [GeForce GT 430] (rev a1)
    09:00.0 VGA compatible controller: nVidia Corporation GF110 [GeForce GTX 560 Ti] (rev a1)

Nvidia-setting also reports both cards the 560 Ti one is recognized as
GPU0 the other one as GPU1.

Currently X11 uses the GTX560Ti and the GT430 is "idle" (has neither
a "display-" nor "rendering-job").


How can I move the "display-job" to the GT430 ? How can I urge X11 to
exclusively use the GT430 for its purposes?

Thank you very much in advance for any help!

Best regards,
mcc

Not an answer, but my little knowledge on GPU processing:

AFAIK, CUDA or OpenCL uses idle resources of the GPU, so I guess that you
are safe even if you don't know (or have ways of) forcing one of them to
X11.

Good luck and happy new year
Francisco

Probably need to see your xorg.conf file. I suspect it comes down to
how the two GPUs are identified there, and how the server layout is
done.

One heads up though about the directions you're going. It might
matter. It might not. In my case I have a GTX465 as my main card
driving two monitors, and then an 8400 GS driving the 3rd monitor.
OpenGL doesn't work at all on the 3rd monitor. I think the way that
stuff works is that it on;y works on the first card, with a possible
exception being that if you use two identical cards (which neither you
or I seem to be doing) then _maybe_ it will work on both.

Anyway, as I know nothing about your Blender stuff, if it requires
OpenGL you might be in for some additional work to get past this
issue. I haven't figured it out here but it hasn't been high priority.
I mostly just use the 3rd monitor for a NetFlix VM.

Good luck,
Mark

CUDA will work on all the NVIdia GPUs if the code is written
correctly. CUDA is capable of identifying all cards in the system as
well as each cards architecture & resources. If the program is written
to give him a choice then CUDA can handle getting it to his GTX 560.

Cheers,
Mark
