Hello.
I was very upset when DisplayLink drivers very slowing my CPU. And all system was very laggy.

I found one solution which is most fast and useful was for me:

1. Edit or create:

$ sudo nano /etc/X11/xorg.conf.d/20-intel.conf 

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"
  Option "VSync" "false"
EndSection

2. Reboot

This solution tried on:

2 monitors

Dell Inspiron 7000
Intel HD Graphics
D3100 dock station.

This solution is described by following link https://github.com/DisplayLink/evdi/issues/51
