I recently upgraded to Ubuntu 18.04 and now my multi-monitor setup with DisplayLink is no longer working properly.
CPU usage is almost at 100% all the time where DisplayLinkManager is using about 80% of it.
Did some one managed to setup DisplayLink on Ubuntu 18.04 and got it working smooth? I would love to play videos on the second screen like I could before.
I am using a Zenbook ux31a.

If you have any peripherals plugged into the dock like say a usb mouse, move your mouse around really fast while watching the process. It will jump from 20% to 150% cpu. Anything plugged into the dock seems to lag the cpu depending on usage. I switched to an older dock that your laptop snaps into and no issues. But if your dock is using usb3, your peripherals are going to blow up your cpu.. especially the mouse while it is in use.
