Displaylink CPU Usage high in Ubuntu 18.04

Drofe · 06-27-2018, 06:05 AM

As I posted in the other thread the fix does not work for me as it is obviously not log writing that is the issue for me.

I'm on a DELL Latitude E7250 laptop with SSD and i7 processor using Xubuntu 18.04 with Xfce using latest 4.2.29 driver.

If I have nothing going on on either display CPU usage is not exceptional (<10%). If I start doing anything like grabbing a window and "wiggle" it the cpu quickly rises to >100%
If I check the threads in top there are threads called DeviceWindowDis and SourceEngine_00 that sky rockets when I wiggle the window.

I experience the same problem on Ubuntu 18.04 with DisplayLink Driver 4.4.24.

Is there any fix?
