Ubuntu 20.04 and High CPU utilization
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 dampel Last edited by dampel; 09-24-2020 at 08:38 AM. Reason: complete |

And finally i-tec cadual4kdock packed and prepared to return. DisplayLinkManager uninstalled. This is waste of time.

Having exactly the same problem - it seems that it's fundamentally broke given the number of complaints, yet nothing seemingly is being done about it.

This has been an issue for at least 7 years. Are there any chance it will be fixed during the next 7 years?
