Run Cisco Webex on 64-bit Fedora 28/CentOS 7

With Audio and Screen Sharing Enabled

IMPORTANT NOTE :

1. The Screen Sharing works when you use Xorg instead of Wayland.
2. In my test, I disabled SELinux but maybe it works even if SElinux is permissive.
3. This was tested and worked on the DELL VOSTRO 3560 but does not work on DELL PRECISION 7510
