18.04 stuck on 640x480

Hallo together

My Hardware
Laptop with Intel® HD Graphics 530 (Skylake GT2)
USB3 Dock: Club 3D CSV-1460, Chipset: DL-6950, 2 Displayports

Fresh Ubuntu 18.04 installation.
Well-known, at Time Wayland does not work together with Displaylink.
XOrg does (Gnome 3.28.2).

For the Installation of the Displaylink driver i used this Script:
https://github.com/AdnanHodzic/displaylink-debian >>> many Thanks

If i connect a Monitor direct via Displayport Cable, the Monitor will only show a resolution of 640x480.
The manual xrandr solution will only generate a big Buffer around the 640x480 resolution of the Monitor.

The Solution is a simple Displayport to DVI Adapter.

For lack of a DVI Port at the Displayport Monitor i used a different Monitor for this Test.
Since i have only one Adapter, i can only test with one Monitor.

Display Rotation is also working.
Plug and Play is working as expected.
A Reboot is working as expected.

It seems to be a very specific Displayport Problem.
