Using XFCE solves the problem. Seems that it's caused by compiz when using Unity.

Default Unity NOT supported

Running
Code:
metacity --replace
gets rid of the high CPU problem. But then you basically are not using Unity anymore.

So Ubuntu Unity ist NOT SUPPORTED by Displaylink. You can pick one of these:

a) Unity with permanent high CPU load
b) Different desktop than Unity
c) Different hardware

We have the high CPU usage and flickering mouse pointer on laptop screen issue also without metacity. Using Ubuntu 16.10. I have two 27" screens connected on the DELL 3100 docking station. The latest Ubuntu driver is installed.

Here is a link to the htop command's output from my laptop:


Another issue is the very low frame rate. See the report from the glxgears program below.

I get an extremely high FPS reported from glxgears:
Code:
$ glxgears 
Running synchronized to the vertical refresh.  The framerate should be
approximately the same as the monitor refresh rate.
303 frames in 5.0 seconds = 60.553 FPS
1203 frames in 5.0 seconds = 240.384 FPS
8173 frames in 5.0 seconds = 1634.242 FPS
9915 frames in 5.0 seconds = 1982.991 FPS
8718 frames in 5.0 seconds = 1743.354 FPS
8002 frames in 5.0 seconds = 1600.181 FPS
8554 frames in 5.0 seconds = 1710.762 FPS
However, it LAGS
