Description of problem:
Started xfce4-panel
SELinux is preventing /usr/sbin/lightdm from 'append' accesses on the file .xsession-errors.

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

If you believe that lightdm should be allowed append access on the .xsession-errors 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 lightdm /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
