Description of problem:
start vlc
SELinux is preventing /usr/libexec/ck-get-x11-server-pid from 'connectto' accesses on the unix_stream_socket @/tmp/.X11-unix/X0.

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

If you believe that ck-get-x11-server-pid should be allowed connectto access on the X0 unix_stream_socket 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 ck-get-x11-serv /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
