Thanks. It looks like this is one of those cases where Nvidia is the
primary GPU with Intel secondary:
Mar 05 12:51:48 Goliat gnome-shell[2271]: Added device '/dev/dri/card2'
(nouveau) using non-atomic mode setting.
Mar 05 12:51:48 Goliat gnome-shell[2271]: Device '/dev/dri/card1' prefers
shadow buffer
Mar 05 12:51:48 Goliat gnome-shell[2271]: Added device '/dev/dri/card1' (i915)
using atomic mode setting.
Mar 05 12:51:48 Goliat gnome-shell[2271]: Created gbm renderer for
'/dev/dri/card2'

Mar 05 12:51:48 Goliat gnome-shell[2271]: Boot VGA GPU /dev/dri/card2 selected
as primary
If your secondary monitor is plugged into the secondary GPU (Intel) then
that requires special support which was added in Mutter 46.5 and 47
which was only released in Ubuntu 24.10. Although even that was only
tested with the proprietary Nvidia driver and not with Nouveau.

So that would make this a duplicate of bug 1978905 fixed in Ubuntu
24.10, assuming the fix that works for nvidia-drm also works for
nouveau.
