    What version are you using? We can pick old ones at http://codykrieger.com/gfxCardStatus/changelog

    fixed that and got it back to nvidia.

    its a shame I can not get the display to do anything other than the crappy 1280x768 resolution no matter what I try. I guess im missing some big step somewhere.

    I believe that means you get VESA frambuffer. You should be able to get nouveau working with full resolution, I get it as soon as I stop blacklisting it. My problem is need OpenCL, and nouveau is not anywhere near supporting that afaik.

    2.2.1, apparently the 'fix' will be released in 2.3:

    Yes, after you did this and boot the first time into OSX, OSX seems to not be able to switch to the discrete GPU. Another reboot fixes this; currently no issue for me, because I am using the laptop with Linux only.

    btw: which kernel versions are you using? pre 3.6-rc3 require a lot of patches. 3.6-rc3 and rc4 should be good with:

    Re: ubuntu on new retina macbook : any experience ?

    Did anyone try a dualboot configuration with linux and windows ?

    I would like to use the intel gpu in linux, but the nvidia gpu in windows ...and get rid of osx on this small harddisk, maybe put it on an external one...

    but as i understood it, OSX is needed to switch the graphics card, right ?

    Currently, yes - but this is only very temporary. As soon as the intel drivers can handle initialization without connected outputs, GPU switching should work in Linux (vgaswitcheroo) without any need of OSX/gfxcardstatus.

    Thanks. When you say "should be good", do you mean I should be able to get the nvidia driver running? Or will it just work well with nouveau?

    I still haven't tried downgrading gfxCardStatus, maybe that's my next step.

    With the listed patches you should be able to use intel and nouveau + have working backlight control. Also suspend/resume should work well enough, although this is about 3-4 seconds slower than it have to be.

    afaik version 2.2.1 (currently most recent one) still contains the bug that we use to force the laptop to boot with the Intel GPU: no need to downgrade. Force integrated GPU, shutdown and boot into Linux.
    Of course, if you want to use the Nvidia GPU only, there is no need to use gfxcardstatus and force the integrated GPU.

    About nvidia blob driver) Try the most recent beta version; backlight control might not work, as the gmux device (that controls the backlight) seems to be disabled somehow by the nvidia driver.
