Lucas,

I had tk installed, so that was not the issue with X11 forwarding. I tested some other programs, like xterm and they also had issues, which I was able to track down to needing to set X11UseLocalhost no on the Rpi. I am now able to get X11 forwarding for xterm, but it's still not working for Pd. Here are the errors I'm getting:

$ pd -lib zexy -open testaudio.pd
X Error of failed request: BadAccess (attempt to access private resource denied)
Major opcode of failed request: 18 (X_ChangeProperty)
Serial number of failed request: 12
Current serial number in output stream: 15

I thought it was permissions related, so I tried:

$ sudo pd -lib zexy -open testaudio.pd
X11 connection rejected because of wrong authentication.
X11 connection rejected because of wrong authentication.
application-specific initialization failed: couldn't connect to display "raspberrypi:10.0"

Could it be that those errors on the GUI are because you have no tcl/tk
installed?

Try:

sudo apt-get install tk

Then start a normal Pd with GUI.
