Is there still no solution in sight? I have tried all above workarounds (patch, and latest displaylink version and vice versa) but it did not work at all.
xrandr gives me many disconnected devices, I did not find them anywhere in the filesystem. ``` $ xrandr --query |grep connected eDP-1 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 381mm x 214mm DP-1 disconnected (normal left inverted right x axis y axis) HDMI-1 disconnected (normal left inverted right x axis y axis) DP-2 disconnected (normal left inverted right x axis y axis) DVI-I-4-4 disconnected (normal left inverted right x axis y axis) DVI-I-3-3 disconnected (normal left inverted right x axis y axis) DVI-I-2-2 connected 1920x1080+3840+0 (normal left inverted right x axis y axis) 510mm x 287mm DVI-I-1-1 connected primary 1920x1080+1920+0 (normal left inverted right x axis y axis) 521mm x 293mm -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1875015 Title: Ubuntu 20.04 and Displaylink is extremely slow Status in X.Org X server: Unknown Status in xorg-server package in Ubuntu: Confirmed Bug description: Using ubuntu 20.04 on displaylink docking with external monitor is totally slow, unusable. The GUI responds very slow, if you click, the command of the click goes on after about 3 seconds... if you type, all the letters are with the same lag, so it is totally unusable. Was using displaylink without any problem on 19.10 until yesterday, when I upgraded to 20.04. It is terrific. If i plug out the usb for the displaylink docking station, than the speed is back, and the system is ok, if I connect it to the docking station again, everything extremely slow again. Please investigate this asap, as it is unusable on displaylink docking stations.
