[Bug 2084046] Re: [i915] Phantom "Unknown" display detected on Intel Meteor Lake

The temporary workaround suggested in the initial description in the bug
report for NVidia, bug 2060268

-----
[ Temporary Workaround ]

1. sudo rm /dev/dri/card0
2. Log in again.

also works here. I did not try the permanent workaround presented there,
but most probably it will also work.

Especially I can now also use the "Mirror" mode with a projector (tested
here on the Engineering Sprint).
