Fedora 23 Server: can't startx

[Braden McDaniel]

I have a fresh, updated install of Fedora 23 Server.  After
installation, I installed the "Basic Desktop" group.  Now, when I try to
run startx, it fails with the error:

        xf86EnableIOPorts: failed to set IOPL for I/O (Operation not permitted)

Where should I look to diagnose/resolve this?  Could this be related to
the fact that my home directories are NFS mounted?  (I have set the
use_nfs_home_dirs SELinux setting to "on".)
