You have been subscribed to a public bug:
Ubuntu cannot use the usb-c as monitor connection. It stopped working last
week. (December 2021)
Unfortunately I don't know which update broke the support, or which package is
involved.
The USB-c port is provided by the nvidia graphics card. (tu116)
This feature is not supported by nouveau driver, only with the closed source
nvidia driver.
I hope this is useful.
Please help me to provide further and better information.
