Default Same here

I am also having a similar problem. Rebooting with the displaylinks disconnected, Ubuntu 16.04.2 boots up fine. Connect the displaylink adapters, and it crashes X11.
I've attached the output from the support tool.

Default Temporary solution

If you installed 16.04.02 you can probably boot using 4.4 kernel.

When booting up press shift to show GRUB. Then choose "Ubuntu with advanced options"(something like it) then on the list choose to boot with 4.4 generic.

It worked for me.

This is, roughly speaking, my experience on Ubuntu 16.04 (kernel 4.4). Initially my system went into low graphics mode whenever I plugged in the DL monitor. This stopped once I altered 20-displaylink.conf to use the "Intel" driver, but that instead caused the system to crash whenever I plugged in the monitor or clicked "Detect Displays" or opened Chrome or looked at it too hard. This is my current 20-displaylink.conf (which is based on a working setup from another user on this forum).

Code:
Section "Device"
  Identifier "Intel Graphics"
  Driver "Intel"
  Option "AccelMethod" "sna"
  Option "TearFree" "true"
  Option "TripleBuffer" "true"
  Option "MigrationHeuristic" "greedy"
  Option "Tiling" "true"
  Option "Pageflip" "true"
  Option "ExaNoComposite" "false"
  Option "Tiling" "true"
  Option "Pageflip" "true"
EndSection
This eliminated the crashes, though X still gives me a load of crash reports on startup and the screen still isn't being detected anyway.

Attached is my system's output from the Displaylink Linux Support Tool. Any pointers would be greatly appreciated.

There is a vga port on the monitor and I will try that but I don't have the right converters at the moment.
I thought Display link drivers were only for USB monitors, not display port, or dvi connected? I have 3 dell i7 laptops with video connectory for display port, DVI and Hdmi running Linux Mint 17->18.3 Ubuntu Based 15->16 just plugging in the monitor to either of the ports with out any DisplayLink drivers, works. No special drivers are required that I know of. Am I missing something about DisplayLink?
