    Planning on getting new pc. I thought about going intel+nvidia desktop. Does Optimus or similar technology work for desktop pc's?

      Immediate answer? No.

      Answer with the next xorg release? More so... Kinda sorta.

      Answer whenever Nvidia writes its own version of DMA-BUF? Yes.


      If you want a more detailed answer google "linux nvidia bumblebee"

        I don't think it would work when nvidia would write a new variant of DMA-BUF, sure they could create a gpl stub driver that just exports the symbols they need but that sounds a bit crazy. There is another trick that is possible that you don't use the real exports but calculate the positions in the Makefile, that would go around the problem but this hack is most likely not allowed as well. So the only way to officially support optimus would be when all kernel developers would allow the use of it via a non-gpl only export - when you look at the last discussion that's unlikely as major kernel developers have got moral problems with that. It's clear that pragmatic owners of such laptops think different.

        Ok, there are userspace solutions if you want to call that solution. It might work for some kind of apps but will most likely fail for others.

          All they need to do is to stop being greedy and release the drivers as open source like Intel does.

            Yes, "all" they need to do is that.

            *rolls eyes*

            This ignorant naivete on Phoronix is really, well, eye-roll worthy. If it was so simple as you want it to be, AMD wouldn't be writing a separate open-source driver that lacks proper power management and other stuff, "all" they'd do is open source Catalyst. But we're not in rainbows-and-unicorns-phoronix-land where it's about some sort of "greed", we're in this place called reality.

              Hey INTEL

              do not just focus on haswell and all your new shit

              don't forget to improve support for the gma's and the gm 45 (this one is quite popular)

              don't pull a ati on us

                Oh, and one more thing:

                Intel does not release their driver as open source, as you say. They too have a separate open driver that is slower (the performance difference is not as big as with AMD and Nvidia though) and has less features (no opengl 4, which their closed driver does have). The only difference is, Intel does not release their closed driver for Linux, at least not publicly.

                  Legal limitations and DRM are the codifications of greed. It may not come directly from nVidia but greed by proxy is still greed.
