Subject: [PD] pd-0.48.1 trouble getting started

This may have already been addressed and in my tendency to ignore pd
list traffic I missed the explanation, but here is what is going on.

I am running a fairly fresh install of Fedora 26. I downloaded the
source to Pd, installed alsa-lib-devel and tk (for wish), then built pd
using makefile.gnu. Everything works when I start pd without super user
privileges, except priority 92 scheduling is denied me. When I start pd
using sudo, pd doesn't start and I get the following errors on the
command prompt:

 >> sudo ./pd
No protocol specified
No protocol specified
application-specific initialization failed: couldn't connect to display

These messages are not particularly helpful for me. Anybody know what is
