Running Ubuntu 12.04 on a 2012 MacBook Air (5,2)

Is there a "how-to" planned for the installation process for Ubuntu 12.10 ? This would be very helpful. :)

Hi guys, first thing thank you for sharing, this thread saved me a lot of time (:

I have a 5,2 MBA and everything works fine, BUT I'm experiencing tons of kernel panics - I would say one every two hours and then I have to force the machine to shutdown by holding the power button (both keyboard and mouse/trackpad are completely unresponsive)

• Kernel: 3.2.0-23-generic #36-Ubuntu SMP
• It doesn't look related to any specific program, last time it happend I was working on Emacs only (although I haven't tried to change DE yet)
• There are no error messages on /var/log/syslog of any kind
• The suspend function works falwlessly

This behaviour is so frustrating though. Has anyone experienced the same issue? Any ideas about what I could look for?

Thank you!

Do you have the noapic option enabled in grub when booting?

Thank you for you reply (:

Yep, I have noapic enabled. Those are my grub options though:

Code:

---

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash noapic i915.i915_enable_rc6=1 resume="

Thank you Scot and everyone else for such a detailed and well written post.

I think this information should be added to the ubuntu wiki/documentation page like the ones below

Installing Ubuntu on Macbook Air 4,2 -- https://help.ubuntu.com/community/MacBookAir4-2

and then it should be linked on to the main Macbook Air page -- https://help.ubuntu.com/community/MacBookAir

Please report here if you find a fix. This affects me too :/

I'm updating to 12.10 to see if a new kernel helps. I will keep you posted.

You can set the default start-up volume by pressing Control-click on an arrow under the volume.

Also, on my Air, the trackpad stopped moving after resuming from S3 suspend. This seems to be fixed by adding the touchpad driver to the power management snippet from the setup script:

Code:

---

echo "Fixing post-hibernate hang."
sudo tee -a /etc/pm/config.d/macbookair_fix <<-EOF
        # The following brings back eth0 after suspend when using the apple usb-ethernet adapter.
        SUSPEND_MODULES="asix usbnet bcm5974"
EOF

Hi, I am using this as a guide for installing Ubuntu 12.10 on a Macbook Air mid-2012 - thank you, it's amazing!

However, somewhere along the line with the changes to the wireless module it stopped working and I can't get it back again. I've taken the obvious steps to reverse what I did:

• Deleted the /etc/modprobe.d/blacklist-bcma.conf file
• Uninstalled (purged) the broadcom-sta-dkms package and removed ppa:poliva/pof from my sources.
• Used Software Sources to install the propriety bcmwl-kernel-source driver

...but it still doesn't work. No other way to get on the net with this machine (I don't have ethernet at home) - help please!

EDIT: I gather the problems with the binary driver are basically fixed in 12.10, based on this post: http://pof.eslack.org/2012/05/23/why...how-to-fix-it/ so there was no need for me to apply the changes anyway... but I have now, so...

So it's fixed?
