Description of problem:
At start.
SELinux is preventing /usr/sbin/lxdm-binary from 'create' accesses on the file .Xauthority.

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

If you believe that lxdm-binary should be allowed create access on the .Xauthority file 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 lxdm-binary /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
