Ubuntu 25.10 - HP HSA-B005DS dock - only cursor on secondary display

[bkozma]

Hi,

My setup is Ubuntu 25.10 with HP HSA-B005DS dock. I can see only the mouse cursor on secondary display, no background, windows, icons.

I tried to reinstall displaylink-driver, evdi, it didn!t fix it.

Do you have any suggestions?
