I thought my DISPLAY was set, but it actually wasn’t. It worked with “:0.0”. 2. “ssh -Y” worked, whereas “ssh -X” did not. Voila! (so far) Thanks for your help, guys.

I am also still getting a “cannot open display: localhost:10.0” error. This is DESPITE the fact that: - I set DISPLAY to “localhost:10.0” - X11Forwarding is set to “yes” in the sshd_config file - I changed the “hosts” file, under /etc to have actual IP addresses. Any idea why this might be happening? Yes. Change that "10" to "0". So it's "localhost:0.0" or even ":0.0". Should work much better.... :) Unless ssh is involved, which was not stated, but I suspect might be part of the issue.
