So it's probably Xubuntu with GNOME added later?

And currently, both GNOME on Wayland and GNOME on X.org work, but Xfce doesn't?

If that's right it eliminates a problem with X.org. Xfce only runs on
X.org, not on Wayland. (Yet. AFAIK.)

In that case it should be fine. There are no proprietary or
alternative drivers for Intel, only for AMD and nVidia.

One possibility: a screwed-up xorg.conf file.

As root, look in /etc/X11

If there is an xorg.conf file in there, rename it to something else,
e.g. xorg.conf-backup, or move it to another folder. Then shutdown &
reboot. This will clear most X.org issues -- modern versions without
proprietary drivers are smart enough to just autodetect everything and
Just Work™.

If you feel confident to do it, I recommend putting /home onto a
separate partition. This means that you can dual-boot >1 copy of
Ubuntu but keep the same home directory and user account.

Sounds dangerous but works fine. Not a problem if you use the same
version of Ubuntu but with different desktops.

If it's GNOME on Wayland, that is normal behaviour for Wayland.

It is intended and they won't fix it:

If it's GNOME on X.org it's weird.
