Here is a quick response without knowing your background or experience with Pd/MIDI/Linux...
1. Do you have Pd's MIDI input enabled? I don't see one listed, just the "Pure Data Midi-Out 1"
2. Are you connecting devices? By default, aconnect doesn't connect anything automatically. I did a quick search and found this which may be helpful if you are not familiar with aconnect or aconnect-gui:
If you use aconnect-gui, basically just connect you devices output to Pd's input.
