Description of problem:
SELinux is preventing Xorg from 'open' accesses on the chr_file /dev/tty2.

*****  Plugin catchall_boolean (89.3 confidence) suggests   ******************

If you want to allow all daemons the ability to read/write terminals
Then you must tell SELinux about this by enabling the 'daemons_use_tty' boolean.
You can read 'bumblebee_selinux' man page for more details.
Do
setsebool -P daemons_use_tty 1

*****  Plugin catchall (11.6 confidence) suggests   **************************

If you believe that Xorg should be allowed open access on the tty2 chr_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 Xorg /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
