["Christopher M. Penalver" <christopher.m.penalver@xxxxxxxxx>]

Vlad Dinulescu, thank you for reporting this and helping make Ubuntu
better.

Could you please test the latest upstream kernel available from the very
top line at the top of the page from http://kernel.ubuntu.com/~kernel-
ppa/mainline/?C=N;O=D (the release names are irrelevant for testing, and
please do not test the daily folder)? Install instructions are available
at https://wiki.ubuntu.com/Kernel/MainlineBuilds . This will allow
additional upstream developers to examine the issue.

If the latest kernel did not allow you to test to the issue (ex. you couldn't boot into the OS) please make a comment in your report about this, and continue to test the next most recent kernel version until you can test to the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this issue is fixed in the mainline kernel, please add the following tags by clicking on the yellow circle with a black pencil icon, next to the word Tags, located at the bottom of the report description:
kernel-fixed-upstream
kernel-fixed-upstream-X.Y-rcZ

Where X, and Y are the first two numbers of the kernel version, and Z is
the release candidate number if it exists.

If the mainline kernel does not fix the issue, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-X.Y-rcZ

Please note, an error to install the kernel does not fit the criteria of
kernel-bug-exists-upstream.

Once testing of the latest upstream kernel is complete, please mark this
report's Status as Confirmed. Please let us know your results.

Thank you for your understanding.

Title:
  miniDisplay VGA adapter doesn't work after switching to 4.2 kernel

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  After switching to Ubuntu 15.10, my miniDisplay port adapter doesn't work anymore, or in rare cases , it works, but it gives a maximum resolution of 1024x768 (whereas the monitor is 1920x1080).  
  Also, when I connect my iphone5 I cannot use the USB tethering anymore.
  If I boot with the older kernel, everything works as expected.

  Hardware info:
  system - dell xps 12 9q33
  minidisplay adapter - minidisplay to vga, made by apple
  iphone - iphone5 with latest ios (9.1)

  new (non-working) kernel = 4.2.0-18
  old (working) kernel = 3.19.0-33
