pisound & Pure Data
Using pisound you can run your Pure Data patches straight from a USB thumb drive with a press of a button with no need to connect an external monitor, keyboard or mouse.
Plug in a USB drive containing your Pure Data patch, main patch file called main.pd, plug in any additional MIDI controller/keyboard, press The Button and Voilà!
You can read more about The Button functionality here.
If you haven't already, you can install Pure Data by running the following command in a Terminal window:
sudo apt-get install puredata
Configuring Pure Data
By default, Pure Data is launched when single-clicking the button as so:
nohup puredata -alsa -audioadddev pisound -alsamidi -channels 2 -r 48000 -mididev 1 -send ";pd dsp 1" "$PURE_DATA_PATCH" > /dev/null 2>&1 &
You may want to customize the command line arguments for Pure Data according to your own needs. To do that, check the Pure Data's Command Line documentation and edit /usr/local/etc/pisound/single-click.sh.
Keep in mind that updating pisound's software will backup and overwrite your scripts, so in that case, you may want to re-apply your changes. See here for more details.
