Research direction

Start by reproducing the issue in a fresh Linux Mint 22 Cinnamon installation with the NVIDIA proprietary driver and X11, then inspect how Display Settings handles the reported "None-1-1" monitor. No source files or tests are named; done means the nonexistent display no longer appears or becomes primary, without relying on /usr/share/X11/xorg.conf.d/20-ignore.conf.
