How do I install a minimal number of packages for an X11 environment to support X forwarding on RHEL 7 for Policy Server installation?
Policy Server 12.7 on RedHat 7
Use the following command to install X11 packages to support X forwarding on RHEL 7:
# yum install "@X Window System"
OR
# yum install xorg-x11-xauth xorg-x11-fonts-* xorg-x11-utils
