I want to start puredata installed on a headless Raspberry Pi, using x-window from a macbook.

In my macbook, I have installed Xquartz, and I connect to my raspberry using the

ssh -X pi@myraspberryip

command with my password.
Xquartz start, but don't display pd user interface... only "priority 8 scheduling failed." is printed on the terminal...

It was working well before, is it broken now?

Raspbian Os bulleye
MacOs Monterey
Xquartz 2.8.5
Puredata 0.51-4

@60hz If the error message is originating from Pd as it tries to start then try making your Pi user a member of the audio group...... https://forum.pdpatchrepo.info/topic/14085/solved-problem-with-pd-start-priority-8-scheduling-failed.
But if it comes from the SSH -X connection (seems more likely) then...?
You mention that normally you would see the Pd user interface on the Mac.
Have you recently updated XQuartz?

Maybe temporarily try a simple VNC server and X11 on the PI, and a VNC viewer on the Mac just to see whether Pd is actually starting up correctly..

Thanks @whale-av
Actually it was working well this way with my old macbook and not this new m1 and monterey...

I run pd from the pi with an hdmi screen and the pd error message is also appearing but at least pd interface could start without issue.

Maybe the issue comes from xquartz then.. I need to investigate but I am not used to linux and x windows server...
