So far as I can tell, the listed resolutions:
nicholas@mordor:~$
nicholas@mordor:~$ cat /sys/class/drm/card0/card0-VGA-1/modes
1024x768
800x600
800x600
848x480
640x480
nicholas@mordor:~$
nicholas@mordor:~$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 22.04 LTS
Release: 22.04
Codename: jammy
nicholas@mordor:~$
match what is shown in setting exactly. However, prior to logging out, higher resolutions were available.
Is there a diagnostic to re-check supported resolutions?
Asked differently, how are possible monitor resolutions detected?
