    Nvidia Optimus coming to Linux?

    I ready here that Nvidia has confirmed that it is working on Optimus so that it can be supported by Linux. This is great news, but what's the realistic outlook of this? When will the actual working drivers come out for Linux?

    I was unlucky enough to buy a powerful mobile GPU, the GeForce GTX 675m, but my computer's BIOS doesn't have the option to disable discrete graphics so I've never been able to use my GPU, except for with Bumblebee but it kind of sucks (it makes most games slower and less stable than with the CPU). So hearing the news that I may one day be able to switch between discrete graphics and Nvidia was really relieving.

    So what do you think about this? When's it suppose to be ready to use on Linux?

    This is really great news since up to this point NVIDIA Optimus laptops have been a pain to use properly under Linux. While there is DMA-BUF/PRIME support for the Nouveau driver, using the reverse-engineered open-source NVIDIA driver isn't ideal there since the driver lacks reliable and useful power management support (a.k.a. a very short battery life and potentially a warm lap). Let's hope this support gets stabilized soon.

    Re: Nvidia Optimus coming to Linux?

    If you and I are reading the same sources of information, then Nvidia is quietly working on supporting Optimus in GNU/Linux environments now. They have not announced an official release date or time to offer Nvidia graphics drivers that support Optimus in GNU/Linux yet. At the very least, you will need to upgrade to Ubuntu 12.10 32 or 64 bit because it has the newer Linux kernel 3.5.2 and it has the new OpenGL 3.x, Mesa 9.0, RandR, and Intel SNA along with X.Org versions that support PCs with multiple GPUs. So, you should think of this as a combined community effort across GNU/Linux for cutting edge distributions to offer Optimus support. Without Nvidia supplying an official graphics driver that supports Optimus, you will have multiple system crashes when trying to invoke Optimus support. Therefore, you should be patient. I would say that it would be more realistic to expect official Nvidia support by Ubuntu 13.04 32 or 64 bit in April 2013 at the earliest possible date. Of course, I am speculating just as much as you are doing so because we don't know how far along Nvidia is making progress. They have a proof of concept working now, but it is in the inchoate stages of official Optimus support for GNU/Linux. My understanding is that you will have to remove the Bumblebee Project to get the official Nvidia Optimus in GNU/Linux support.

    I don't think Optimus will ever come to Linux. Integrated will get so good & power efficient it won't be needed.

    Integrated graphics are already very power efficient, but that's the problem. They're focused on power efficiency instead of raw power. A dedicated GPU is always going to be far more powerful than integrated graphics.

    That may be true for now, but the future direction in which Intel is taking in particular leads me to believe that integrated graphics will be up to snuff with AMD and NVIDIA GPUs in the next two years or so. For example, Intel's next generation Haswell CPU will double the graphics performance from Intel HD Graphics 4000 with its top of the line CPUs next year. This will mean that it will offer pretty good graphics performance and an AMD or NVIDIA GPU will be optional. In the next two years, I expect Intel's integrated GPU to be close in terms of performance to that of AMD and NVIDIA's second to the top of the line GPUs, but they will be much more power efficient and the CPUs and GPUs will be much smaller so that smaller form factor desktops and notebook PCs will be able to take advantage of these next generation Intel CPUs.

    Take a look at the Intel HD Graphics 4000. It will play World of Warcraft at over 30 FPS at low to medium graphics settings. Who can tell me what will happen to Intel CPUs and integrated GPUs in the next two years from today?

    Of course Intel's integrated graphics will improve, but Nvidia and AMD will just respond by making more powerful (and less efficient) dedicated GPUs. It'll just be an arms-race (or rather, it'll continue as an arms-race). For example, I have the Intel HD 3000, but an Nvidia GeForce GTX 675m, which is quite good. By the time Intel matches the 675m while keeping low power usage, Nvidia will come out with an even better one (for gaming laptops at least).

    Is the Haswell CPU's integrated graphics as efficient as the 3000/4000?
