Anyone know if there is any documentation suggesting that the standard Kernel not support multiple Thunderbolt displays?
From what I can tell, the OS does not even detect an additional monitor.
This is an issue whether I daisy-chain the monitors or use the second Thunderbolt input.
xrandr -q output:

Hi, if you have the late 2013 model (MacBook Pro11,X) you can see my post here: https://bbs.archlinux.org/viewtopic.php … 6#p1454586

This seems to be a slightly different issue than what your post addresses.
With thunderbolt displays, it seems like the system will only recognize one of them. xrandr doesn't show them as connected, as mentioned in your post.
I have a mid 2014 (11,1) macbook pro, and I have the same issue. Very curious to see if it can be remedied.

Yes, it is a slightly different issue, but it is good to know that it CAN work.
Perhaps this is a driver issue? hrod, which display drivers are you using?

Oh sorry, i assumed you meant DP. I don't have any thunderbolt displays so i can't have a crack at it. I have the intel only rmbp so: xf86-video-intel-2.99.917-1
