Smile Solution Ubuntu 16.04.2

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:

Code:
$ 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

Hello!

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).

Thanks sandra1n
The solution you described worked for me.
I'm on Xubuntu 17.04 on Thinkpad T450 and using ThinkPad Pro DisplayLink port replicator.
After installing the DisplayLink driver as per instruction, all I've got on external monitors was black screen with mouse moving.
After applying the workaround from post above, both monitors work.

Hardware:
Lenovo ThinkPad T450
DELL 23' - connected via DisplayPort to dock.
SAMSUNG 22' SyncMaster B2240 - connected via DVI to dock.
Lenovo ThinkPad USB 3.0 Pro dock.

Software:
Xubuntu 17.04
