SELinux is preventing /usr/lib64/xfce4/xfconf/xfconfd from 'write' accesses on the diretório /var/lib/gdm.

*****  Plugin catchall (100. confidence) suggests  ***************************

If you believe that xfconfd should be allowed write access on the gdm directory by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep xfconfd /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
