Wayland session not working with duplicate GNOME entries in greeter
Some greeters (lightdm-webkit2-greeter for example) do not support two sessions with the same name [1]. To check for duplicate entries:
ls -1 /usr/share/wayland-sessions /usr/share/xsessions
Rename the duplicate entry in /usr/share/xsessions. For example:
mv /usr/share/xsessions/gnome.desktop /usr/share/xsessions/gnome.desktop.disabled

I tried this first.

As root, I did the rename.
Then I re-booted.

The menu had only one GNOME entry, as expected.  I tried it.
After about a second, I got the login screen again.
I switched to the GNOME on Xorg and logged in.
I got a system problem and a SELinux alert.
I think the system problem is the same as the one I reported in a newer thread earlier today.
The SELinux alert complains...

The source process: gdb
Attempted this access: open
On this file: /car/cache/fwupd/metainfo.xmlb

and suggested doing this...

# ausearch -c 'gdb' --raw | audit2allow -M my-gdb
# semodule -X 300 -i my-gdb.pp

which I did as root.

I rebooted.

Same results logging in to GNOME.
Same results logging in to GNOME on Xorg.

As root,
I put the gnome.desktop.disabled back to gnome.desktop.

The menu is back to the way it was (2 GNOME entries).
But I'm still getting the SELinux alerts and the system problem.

I thought it best to check back with you before trying gdm (which I already have) or sddm (which I don't yet have).
