    Thanks for replies, I've found a solution.

    I am using the xvfb-run command:

    xvfb-run pd-extended patch.pd

    Which will run the pd-extended command on a virtual display, without returning any errors.

    Hi David,

    I have installed the x11vnc package am running the server with the command

    x11vnc -display :0

    Pure Data still gives the same no display error. What command are you using to run x11vnc?

    I am trying to run my Pure Data patch on a Raspberry Pi without a screen.

    It runs fine when I attach a display and launch it from the command line.

    However if I use the -nogui command line argument, the patch reports:

    ALSA input error (snd_pcm_open): Device or resource busy

    And I am unable to run it normally without a screen plugged as it reports this error:

    Application initialization failed: no display name and no $DISPLAY environment variable

    Why does adding -nogui stop the program running? Otherwise what's the best workaround?

    Thanks in advance, Slidon
