Hi,
I've found this forum because of problems with CPU utilization after I bught docking station i-tec cadual4kdock and I'm using it with Dell Latitude 5591 i7-8850H
Intel UHD Graphics 630 and two monitors 2K and 4K
At the begining I use XFCE and CPU usage was more than 200%
After some reserch I found some improvements
1. Switch to Gnome Wayland
2. Update kernel to newest one - now it is 5.6.0-1028-oem
3. Update BIOS for Dell to 1.13.1
4. install graphics drivers from repository ppa: oibaf/graphics-drivers "4.6 Mesa 20.3.0-devel (git-924e276 2020-09-23 focal-oibaf-ppa)"
Now one DisplayLinkManager process use about 15% and second about 4%.
When I move mouse
it jumps to about 50% but during meetings, teams etc. DisplayLinkManager sill eat over 200% of CPU.
It's much better but not pefrect.
DisplayLink Team do you work on some improvements for Linux users?
Best Regards
