That sounds like bug 2084407 which is in progress.

This file shows xdg-desktop-portal-gnome is crashing on login sometimes,
but that may not be the cause of the white screen crashes. Please follow
https://wiki.ubuntu.com/Bugs/Responses#Missing_a_crash_report_or_having_a_.crash_attachment
for those.

If you want the ability to set different scaling factors per monitor
then you need to be using a Wayland session.  Having Nvidia in the mix
makes that more difficult and potentially buggy but you should check to
see if 'Ubuntu on Wayland' is an option at the login screen (bottom
right corner).

Starting in Ubuntu 24.10, Wayland will be used by default even if Nvidia
is present. But I can't recall a good reason right now why you shouldn't
be able to select the Wayland option using Ubuntu 24.04.
