DisplayLinkManager 1.1.62 - ERROR: modprobe: ERROR: could not insert 'evdi': Required

I do not have the experience. If I do not mirror the displays, the external display is extremely jerky. The display is fluid when I mirror the displays, but still DisplayLinkManager uses 20% CPU while idle - currently, it even stays at 70% even if I am not typing. It all works poorly, and that on a Dell XPS 13 that officially is supported for Ubuntu.

Yes, I have a very low performance and I'm using a Yoga 3 laptop, so I can feel that lots of power is used to update the external display.

Doing nothing, it uses 8% of CPU, and just moving the mouse in the external display goes up to almost 50%
