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
