In trying to see the difference in memory a VM uses when logging with
Wayland vs. Xorg, the screen sharing attempt under xorg failed for some
reason, but worked later:  1.22 GB Xorg vs 1.14GB under Wayland running
Ubuntu 22.04 Desktop.

Wayland is working better on mirrored monitors with the Nvidia 565 driver
than under the 560 driver, but still fails to restore properly after a
suspend/restore.  I'm using Wayland daily, since using the xorg choice at
login results in a minute delay getting windows to display/function
(drag/resize) resulting from some xdg-desktop-portal-gtk issue.
