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

As per http://www.dell.com/support/home/us/en/19/product-
support/product/xps-13-9333/drivers/advanced an update to your
computer's buggy and outdated BIOS is available (A08). If you update to
this following https://help.ubuntu.com/community/BIOSUpdate does it
change anything?

For more on BIOS updates and linux, please see
https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette
.

Please note your current BIOS is already in the Bug Description, so
posting this on the old BIOS would not be helpful. As well, you don't
have to create a new bug report.

Once the BIOS is updated, if the problem is still reproducible:
1) Please provide the output of the following terminal command (not perform an apport-collect):
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date
2) Please make a comment specifically advising on if there was an improvement or not.
3) Please mark this report Status Confirmed. If it's not reproducible, please mark this as Invalid.

Thank you for your understanding.

Title:
  displayport MST external monitors don't return from sleep mode

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  When displays go to sleep, upon return from sleep the two monitors
  attached to a belkin mini displayport to 2x HDMI, do not return from
  sleep. This results in part of the desktop being inaccessible, until
  the external displays are unplugged, and then plugged back in.

  Sometimes, Xorg will also back down to one monitor. The data
  accompanying this report is for an instance where the power save mode
  caused Xorg to drop to the primary monitor only.

  This is on Ubuntu 15.10 on a Dell XPS 13 (9333) with integrated intel
  HD 4400 graphics. There are two external monitors connected by HDMI to
  a belkin DP-MST adapter which connects to the mini-displayport. A
  single-HDMI-to-mini-displayport belkin adapter works as expected
  (coming out of power save).

  xserver-xorg-video-intel:
    Installed: 2:2.99.917+git20150808-0ubuntu4

  Expected behavior: Displays go to sleep, and upon returning all
  displays are still present and all wake.

  Xorg.0.log, relevant happenings:
