    It should be up to hardware manufacturers to at least have a hard switch or bios toggle for choosing which graphics chip to use. In other words, SWITCHABLE GRAPHICS SHOULD BE TIED TO A PARTICULAR OS.

    But from linux side is it not possible to detect if a laptop has noth nvidia card and another one and let the user choose which of the one to permanently use by backporting/disabling the other one?

    PS on ATI side are there any strange features to avoid like this one of Nvidia?

    Wrong, Apple has it's own built in house implementation. Nvidia had nothing to do with that.

    I for one will not consider nVidia products in the near future.
    The main area that you get the benefit of the common drivers is in the HW enablement and generic validation. You can leverage a lot of the testing to ensure the products are mostly stable. With features that begin to get tied to the OS, you don't get the same leverage.

    Optimus as implemented by NV is built heavily around the Vista/Win7 architecture. That doesn't translate to the Linux in any meaningful way.

    Hence it's very expensive to port to Linux where it isn't going to be a clear differentiator that results in return on investment. The most likely source of improvements will be from the the efforts of avilella earlier in this thread. But you won't get NV's driver working on that until there is a generic architecture that supports it in a vendor neutral and vendor friendly way.

    In most cases it does, yes, but I've found little subtleties in different nvidia cards before...

    We've created a Launchpad team called https://launchpad.net/~hybrid-graphics-linux that is a group of hybrid graphics laptop owners and/or developers interested in getting it to work 100% under Linux.

    Please subscribe to this team if you are new by clicking on the "Join Team" link at the right of https://launchpad.net/~hybrid-graphics-linux.

    Use the mailing list hybrid-graphics-linux@lists.launchpad.net to report on your testing.

    ACTIONS:
    We are looking for students with basic Linux kernel/graphics notions interested in applying for the X.org Open Source PRIME multi-gpu support Google Summer of Code 2010:
    http://wiki.x.org/wiki/SummerOfCodeIdeas

    We are looking for Linux users with Nvidia Optimus-enabled laptops willing to provide debugging information for Open Source PRIME multi-gpu support features being worked on. Please join the team by clicking on "Join" on the right, fill in this doodle:
    http://www.doodle.com/63fyczzrxqaquhqx
    and send an email to the mailing list specifying your laptop model with these commands:
    sudo dmidecode -s system-product-name
    sudo dmidecode -s system-version
    lspci -vnnn | perl -lne 'print if /^\d+\:.+(\[\S+\:\S+\])/' | grep VGA

    Last week we reported on GPU switching and then delayed GPU switching coming to Linux via some Linux kernel hacks, but today NVIDIA has launched a new technology for dual-GPU notebooks and that is "Optimus Technology." NVIDIA's Optimus is similar to the hybrid-switching technologies that have been available on notebooks up to this point for switching between ATI/AMD, Intel, and NVIDIA GPUs on notebooks depending upon the graphics workload, but with Optimus the experience is supposed to be seamless. With NVIDIA's Optimus, no manual intervention is supposed to be needed but the notebook will automatically switch between onboard GPUs depending upon the graphics rendering workload. This technology was just launched today via a press release and can be found on a few select notebooks...
