I read that gdm uses the "adwaita" icon&cursor themes by
default.  So I looked into the adwaita packages available:

$ apt list 'adwaita-icon-theme*'
Listing... Done
adwaita-icon-theme/jammy,now 41.0-1ubuntu1 all [installed,automatic]
adwaita-icon-theme-full/jammy,now 41.0-1ubuntu1 all [installed]
$

The full version of adwaita, adwaita-icon-theme-full, was not installed,
only the basic version, adwaita-icon-theme.

I installed the full version and the login screen mouse pointers 
appeared.  Removed the package and I was back to the white square.
Reinstall the full version and I got pointer icons again.

Sounds to me as if the full "adwaita-icon-theme" package should be
a gdm dependency or the cursor icons from the full package should
be added to the automatically installed basic package.


I put "partially solved" in the subject as I still do not know how
to determine/set/change the cursor theme used by gdm.

Thanks for listening,
Jon
