Need help with SELinux

I got this error. Can anyone help?

Code:

$ system-config-selinux
No protocol specified
Unable to init server: Could not connect: Connection refused
No protocol specified

system-config-selinux doesn't work on Wayland. Either change to Xorg or stop using graphical tools that require root privileges to draw their UI. There are command line tools to manage SELinux (semanage, setsebool, whatever).

If you insist on running system-config-selinux on Wayland, use the workaround suggested by Axel Simon in the comments to RHBZ#1274451, that is:

Code:

xhost +si:localuser:root
system-config-selinux
xhost -si:localuser:root

You may even make it a shell alias:

Code:

alias scs='xhost si:localuser:root;system-config-selinux;xhost -si:localuser:root'

Or wait until GNOME 3.34 with this fix lands in CentOS.
