The resulting experience is no graphical display and no terminal display anymore on the integrated display of the laptop (whereas external HDMI display are still available)

The only workaround that I'm aware of is reboot.

I filled the bug through `ubuntu-bug linux` so hopefully you get all additional information you need. If not, feel free to ask.

Thank you for your help,
Best regards,
C.R.
