Hi Mike,

the file permissions only need to be fixed for the next login.
During startup, the xauth command needs the selinux file permissions
of *unconfined_u:object_r:xauth_home_t:s0* or of 
*unconfined_u:object_r:user_home_t:s0* to the .Xauthority file,
so that it can overwrite the file with the new Xauthority Information.
After that, everything works fine for the session.
At least for my test, where I did login and opened a terminal window.
Maybe I should try opening some more kde and gnome applications.
On my system, it is ok, when the permissions will be fixed at logout time.

Sincerly

Frank
