When I first got this one in October 2011 the wireless card wasn't yet 
supported in the latest kernel, so I tried to keep up with the rc releases for 
a couple of months.  I don't usually have a problem working the processor with 
kernel compiles and virtual machines, so I have noticed a bit of heat (I 
actually assume that's what caused a screen problem last week).  It seems to be 
running 10 - 15 C cooler now... I don't know if switching to grub-efi from 
grub-legacy has anything to do with that.

Well, the entire office has this exact same hardware setup. Some run
stock OS X, some run Windows and I run Arch :) All of our machines
seem equally hot (which iMac's tend to do) so I don't think there any
power management issues that stand out.

One disappointing thing was the Catalyst perfomance. Occasionally, it
caused some mouse cursor and compositor corruptions. Though I'm told
these happen in a lot of systems using Catalyst, so it's not iMac
specific. Switching to xf86-video-ati solved all that

What else? Wireless (ath9k) is perfect, so is bluetooth, suspend,
hibernate, webcam, microphone. No glitches, crashes, corruptions,
nothing. It just works!

If you decide on trying it, I'd be glad to help out with any issues.

Cheers.

A bit OT here.
D.: is there any remarkable difference worth noting between running Arch on
PC and on a Mac?
I'm thinking in something like heat or some part of the HW not being fully
supported like the keyboard or anything else. There's no doubt Apple
products stands out because the excellent hardware, one of the main reasons
one would argue to install GNU/Linux on them, but as I never tried this and
I'm a bit reluctant to mess with HW glitches I would love to hear from an
archer running his system on Mac.

Good to hear it's working. Though I can't afford that much downtime at
work to try and see if it works on the iMac as well.

If anyone has experience with the "iMac (2011 or later) + Linux + EFI"
combination, I would love to hear about it.

Cheers,
Can

I used the legacy stuff until last week, when I had to send in the laptop to 
get the screen fixed.  I figured I would try the pure-EFI boot and see if I 
could get it working this time.  I updated the "Macbook Pro 8,1 / 8,2 / 8,3" 
wiki page with the grub config changes I had to do, so hopefully this is the 
last time it's an issue!

I don't know if this is the only solution to the problem, but I have use
the legacy stuff here, too.

Hi,

Brainless software engineer here. I'm using Arch on an iMac 27" + 27"
Cinema Display at work and I couldn't be happier. Sure, it took an
extra 15 minutes to set it up (compared to a PC) but it's quite worth
it. If you are not capable (or willing to) answer a technical
question, please refrain from sending these "how dare you do something
I don't approve of!" messages.

Thanks.


@Bryan: I tried setting this up with EFI but it simply wouldn't work
so I tried using legacy boot mode + grub-legacy and it all went
perfectly.

Because OS X is not about the developers anymore. My father uses OS X.
He is the target user now, not me. I can try to install everything I
need next to the outdated crap Apple delivers or I get rid of the OS and
install a Linux I can make jump through every hoop I want it to. :D

But sorry, I have no idea about the original problem. I have the feeling
that I might have been run into that too, but I don't know what I did
about it. :(

Best regards,
Arvid

Mostly because I like Linux / Arch better...?  It's a personal preference
thing :)

Anyway, I just ran across this thread with the solution:
https://bbs.archlinux.org/viewtopic.php?pid=1216670.  I had to add the four
"outb" lines to grub to turn off the radeon card and enable the intel card
and then everything worked.

Seriously, I never understood people who ever think of using a
non-OS-X OS as your primary OS on a Mac.

[arch-general] MBP 8, 2: Screen(s) found, but none have a usable configuration

[bjsch...@gmail.com]

Hi everybody!

I just installed Arch on a MacbookPro 8,2 in EFI mode (booting directly
from Grub 2).  My system boots, but when I try to start X I get "(EE)
Screen(s) found, but none have a usable configuration".

I've tried changing the modeset values for i915 and radeon (mentioned on
this wiki page:
https://wiki.archlinux.org/index.php/MacBook_Pro_8,1_/_8,2_/_8,3_(2011_Macbook_Pro)#EFI_Boot)
but nothing seems to work.

My modules line in /etc/mkinitcpio.conf is: MODULES="ahci libahci
crc32c-intel intel_agp i915"

Does anybody know what I'm missing?

Thanks!

- Bryan
