From log it looks like the wlroots handles everything right because it founds the display even the resolutions are correct but there is something with IPC so that's why I am submitting the issue here.

GPU hotplug (which includes displaylink) isn't really something that is expected to work at the moment. Displaylink-like devices are especially weird, and probably requires some extra kind of support.
I'm aware of some work that Pekka Paalanen was doing for Displaylink support for Gnome a little while ago. I'm going to wait and see what the results are from that, and apply it to wlroots.
