xauth fail to regenerate the .Xauthority file because of selinux. I seen
this on many F12/F13.
You can test this by removing .Xauthority* files and put selinux in
permissive mode.
My solution was to generate a custom policy file:
>>>>>>>>>>> xauthI.log <<<<<
type=AVC msg=audit(1275899931.248:12726): avc: denied { write } for pid=2989 comm="xauth" name=".Xauthority" dev=sda6 ino=652876 scontext=unconfined_u:unconfined_r:xauth_t:s0-s0:c0.c1023 tcontext=system_u:object_r:xdm_home_t:s0 tclass=file
type=AVC msg=audit(1275899931.252:12727): avc: denied { read } for pid=2989 comm="xauth" name=".Xauthority" dev=sda6 ino=652876 scontext=unconfined_u:unconfined_r:xauth_t:s0-s0:c0.c1023 tcontext=system_u:object_r:xdm_home_t:s0 tclass=file

type=AVC msg=audit(1275900681.673:13378): avc: denied { unlink } for pid=4453 comm="xauth" name=".Xauthority" dev=sda6 ino=653013 scontext=unconfined_u:unconfined_r:xauth_t:s0-s0:c0.c1023 tcontext=system_u:object_r:xdm_home_t:s0 tclass=file
<<<<<<<<<<<<<<<<<<<<<<<<<<<<
# cat xauthI.log | audit2allow -M xauthI
# semodule -i xauthI.pp
(do not forget to re-enable selinux if required).
Also have a look in xauthI.te:
#!!!! This avc has a dontaudit rule in the current policy
So this is why you wont see an "avc: denied" in /var/log/audit/audit.log.
