Hello everyone,

I have recently bought this dockstation : https://eu.ugreen.com/products/copy-of-weekly-sale-product-9-in-1-usb-c-docking-station. It works perfectly with my Framework laptop which has Windows installed but with my P16 it is another story...
I try to follow the procedure on the official website as well : https://www.synaptics.com/products/displaylink-graphics/downloads/ubuntu but same issue.
I am using Wayland because with X11 my laptop is crashing after few second and it is written that we can use Wayland (https://support.displaylink.com/knowledgebase/articles/684649).

When I typed : xrandr I can see my host and my 2 extended screen. The systemctl status displaylink-driver.service is runing and the result of the following command dkms status is :
evdi/1.14.10, 6.11.0-26-generic, x86_64: installed
evdi/1.14.9, 6.11.0-26-generic, x86_64: built

I can clearly see my screens in the Display section and I can even see my mouth on these screens but it is impossible to see an image or whatever. I tried to bebuged it for plenty of hours but I start to give up.. With the dockstation G4 of HP it is working perfectly without doing any modification.

If any one has the solution of an idea it will be amazing !

Thanks a lot :)
