    Question How does Ubuntu perform on early 2011 15" macbook Pro?

    I'm very much interested in running Ubuntu (64bit) on the new 15" macbook pro (8,2), but I would like to get a bit more info about it. So if you own a 15" macbook pro could you please help me by answering the following questions:

    1) Can you switch of the AMD Radeon GPU to save power?
    2) Does the Thunderbolt port allow you to use an external monitor?
    3) What is the battery life under Ubuntu? (please describe your usage)

    Some more 'advanced' questions:

    4) Is the quadcore benificial for running full disk encryption (due to the extended AES in Intel's 2.2 i7 cpu)?
    5) What kind of IO throughput do you get with and without full disk encryption (please describe if you use SSD or HD incl RPM)
    6) Can you tell me the exact type of Broadcom wireless chip used for wifi?

    I would very much appreciate any answers to these question, thanks in advance!

    I have an 8,3 (17"), which is very similar.

    (1) You can supposedly boot using EFI to use the integrated *Intel* graphics, but I've never managed to get that working. The AMD GPU works perfectly.

    (2) Yes, works like a charm.

    (3) Battery life is good. Tweaking everything to low power, I get the machine down to about 20W of power usage, which should be good for 4 hours or so.

    (4) No idea.

    (5) W/o encryption - and with an OCZ vertex 3 and my kernel tweaks to run in AHCI mode, here's a bonnie++. I would say pretty good.

    I'd love to know any tweaks you did or anything you did to get the wifi working. I really want to upgrade my 17" 5,2 to the 8,3 but looked like there was a bit i'd have trouble getting to work. mainly wifi. but i also planned to get the vertex 3, what kernel tweaks did you make for ahci mode?
