Default I have a similar problem: system always hard-crashes

Once I connect the displayport cable to the device, system crashes.

Ubuntu 16.04.2
Kernel 4.8.0-52-generic

Have a GeForce GTX 660M using Nouveu display driver.
Output of support tool attached.

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.

Default I'm fixed

Updated kernel to 4.12 and then applied X11 config as in displaylink support
