Smile Solution Ubuntu 16.04.2

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"
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

Good to know it's works for you, but unfortunately this solution is useless for Ubuntu Gnome 17.04 and Lenovo ThinkPad USB 3.0 Dock (model DU9019D1) combination - screen just stay black. I guess soon you could get same issue with Ubuntu 16.04.3 (which include kernel and Xorg from 17.04).
