    [ubuntu] Re: 2012 Macbook Battery Life?

    You have both an Intel GPU and ATI Radeon right?

    Your high energy consumption is likely mainly due to having both GPUs running whereas OS-X switches between them and powers-off one when not used....
  2. [ubuntu] Re: ubuntu on new retina macbook : any experience ?

    10W is what I get. I still have to echo OFF to power-down discrete (NVidia) GPU.
  3. [ubuntu] Re: ubuntu on new retina macbook : any experience ?

    In my case, I had to leave gfxCardStatus running while shutting-down OS-X.

    Or, it takes to reboots to make it stick. Not sure which.

    I have read your post recently, and I agree that most people will not be able to use your method.

  6. [ubuntu] Re: ubuntu on new retina macbook : any experience ?

    But you still need gfxcardstatus 2.2.1 in OS-X to get this to work, right?

    I think you also need nouveau kernel module loaded to get vgaswitcheroo/switch.

  7. [ubuntu] Re: MacBook Pro 9,1 (mid 2012, non retina, 15") Sleep Raring 13.04

    Switching to Intel GPU seems to solve this problem for 3.7.5 and 3.9.0 rc7 kernel! I have not tried 3.8 kernel yet.

    So, probably not a Ubuntu issue, but somehow a nouveau issue. Just guessing.

    [ubuntu] Re: 2012 Macbook Battery Life?

    On train tonight, Battery history indicates I used 15% in 1 hour. So at this rate I would get 7 hours. My 10 month old battery seems to have 95% initial capacity. 7 times 0.15 is 95%.

    UPDATE:...
  9. [ubuntu] Re: ubuntu on new retina macbook : any experience ?

    I think the first ensures that the idle GPU is powered up (which is NVidia in your case) and the third powers the idle GPU off (which again is NVidia).

    Ok. You have a MBP9,2. It is a little different, but WiFi should be same.

    Install these packages

    Is there a pattern? If it is your accelerometer in combination with some wake event, then this should be easy to test by simulating a bike-ride.
