Re: Thinkpad W520

 

Thanks, bumblebee works for me. Without powermanagemnt, though, but i already figured that that's still in development. The nvidia crad scores more than 3 times better than the intle one does.
A big thanks to you!

Try Bumblebee or Hybrid-windump. Ironhide is another fork of Martin from the original MrMEEE/bumblebee codebase where Bumblebee-Project/Bumblebee is rewritten and maintained by more developers.

    try: Should I use Bumblebee, Ironhide or hybrid-windump?

    By default, the Mesa libraries are already installed. After
    installing nvidia-current (the nvidia
    driver you've installed through the jockey), the default becomes
    nvidia sinds it takes precedence
    over the mesa ones. To change that, use:

         update-alternatives --config i386-linux-gnu_gl_conf
    /usr/lib/i386-linux-gnu/mesa/ld.so.conf
    Repeat it for x86_64 if you run a 64-bit OS.

    Note that Optimus is not supported for Linux, so you really have
    to use a solution like
    Bumblebee or change your BIOS settings.

        Yes, I'm still using Ubuntu, it's oneiric on my laptop. How
        can I install them side-by-side? I installed the nvidia
        driver via jockey, but i didn't see any configuration there.
        Should i just install it and then change the alternative?

        Hi,

        Are you still using Ubuntu? (I noticed Dapper Drake in your
        email.)

        Ubuntu allows for having the libraries installed
        side-by-side and then use the alternatives
        system to set the OpenGL at your choice. Bumblebee sets the
        default driver to Mesa
        (necessary for the Intel GPU) and sets the ModulePath to the
        one containing the nvidia
        drivers.

        For the Bumblebee project, see
        https://github.com/Bumblebee-Project/Bumblebee.

            Hi guys,
            I have a new Thinkpad W520 with Nvidia Quadro 2000M and
            an Intel HD 3000.
            Maybe you know that it has a hardware mux, so I could
            use both of them, but I have to switch in BIOS and
            install/uninstall the nvidia driver.
            In optimus mode, I can only use the Intel card,
            including 3D acceleration for it (if nvidia driver isn't
            installd), but the nvidia card is still active. Thanks
            to acpi_call, i think i managed to disable the nvidia card:
            I have to unload nouveau ( rmmod nouveau ), then to load
            acpi_call ( modprobe acpi_call), and then I can run
            test_off.sh, which works with the method
            \_SB.PCI0.PEG.VID._DSM. After that, the card still shows
            up in lspci, but it doesn't show up in powertop anymore.
            I adapted Erik Andresen's script for his T420, and now
            it works for me.
            But there are still 2 problems left:
            1. The rc6 sleep state of the intel gpu doesn't work
            (not really a problem for this mailing list, i know)
            2. I can't use 3D acceleration parallel with both GPUs.
            Do you know a way how to install the intel and the
            nvidia driver parallel without letting nvidia's one
            overwrite the intel libraries for 3D (I think that's why
            the intel one doesn't accelerate when nvidia driver is
            installed)?
            If i could install them parallel, my next step would be
            to try out ironhide or bumblebee.
            Thanks in advance, and sorry for my english,
            Matthias
