As the machine experiences certain higher-level issues (e.g., we had to manually force xorg with WaylandEnable=false in /etc/gdm3/daemon.conf), we'd like to track down the most important error message in the log first – to the extent possible (yes, we know that nouveau is reverse-engineered and tried to use the proprietary nvidia driver – it deserves bug reports of its own). I can't post the full log for privacy reasons, but specific details are certainly possible when asked.
