This is a two GPU machine 03:00.0 Display controller: Advanced Micro Devices, Inc. [AMD/ATI] Navi 23 [Radeon RX 6600/6600 XT/6600M] (rev c3) 08:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Cezanne (rev c5) The Desktop Environment (gnome with Xorg) is running on the integrated Cezanne, but when I connect the external HDMI cable I get a dmesg resume message from the Navi GPU. So this either requires some additional configuration effort on my part or this is a story for another bug report.
