The port it's connected to is a Thunderbolt port, but the screen only
uses USB-C
An idea what's happening?
libdrm: 2.4.124

Hi,
could you please open a ticket at
https://gitlab.freedesktop.org/drm/i915/kernel/-/issues/new
and attach there a dmesg log booting with drm.debug=0x15e and
reproducing the problem?
Thanks,
Imre
