Title:
MacbookPro 12,1 Apple external VGA thunderbolt/displayport display
non-functional
Status in linux package in Ubuntu:
Confirmed
Bug description:
The Apple VGA thunderbolt/displayport adaptor seems to be non-
functional on my MacbookPro 12,1. After plugging it in with a
projector attached, the projector does not show up in the display
control panel and xrandr reports DP1, DP2, HDMI1, HDMI2 and VIRTUAL1
displays all disconnected. When inserting the adaptor, the following
is printed in kern.log:
> Nov 26 16:13:26 payens kernel: [ 498.959901] thunderbolt 0000:07:00.0:
resetting error on 0:c.
> Nov 26 16:13:26 payens kernel: [ 498.959926] thunderbolt 0000:07:00.0:

> Nov 26 16:13:27 payens kernel: [ 499.161674] [drm:gen8_irq_handler [i915]]
*ERROR* The master control interrupt lied (SDE)!
The last line repeats ~20 times.
I tried tried 4.4-rc2 from the mainline kernel PPA, and the same thing
occurs.
