Autostart with the Desktop

Sometimes one needs the X Windows system to run a Pure Data patch on a Raspberry Pi. This is the workaround for an autostart of a PD patch after booting in the desktop.

Make a Autostart File

Make the folder and the file for the autostart:

  $ mkdir /home/pi/.config/autostart
  $ nano /home/pi/.config/autostart/my_pd_autostart.desktop

Type in the following lines:

  [Desktop Entry]
  Type=Application
  Comment=start a PD-patch
  Name=PD patch
  Exec=pd /home/pi/PD-sketchbook/my_pd_file.pd

Save it with ctrl+o, then hit return and then ctrl+x.

Run the Raspberry Pi Headless

To start the desktop even no monitor is connected one has to do some changes.
In…

  $ sudo nano /boot/config.txt

Uncomment the following line:

  # uncomment if hdmi display is not detected and composite is being output
  hdmi_force_hotplug=1

Save it with ctrl+o, then hit return and then ctrl+x.

That's it, your PD patch should run after rebooting the Raspberry Pi.
