No auto start, unless ssh?

[Logan-Orr]

Hello! In the new PlV 1.3 update, the autostart is no longer working, i know how to manually start it and it works, but when i put the sudo python3 /home/Piano-LED-Visualizer/visualizer.py & in etc profile, it does not start, but when i ssh into it, it automatically starts up and the menu is shown with no commands entered, and if i close the ssh window, it stops working, how can i fix this?

Hello. https://github.com/onlaj/Piano-LED-Visualizer/issues/349#issuecomment-1109641040

I will try to fix that in future updates, for now try this workaround.

So I looked at that yes, where would i find the crontab?

[onlaj]

Type: sudo crontab -e

[Logan-Orr]

Thanks bro u respond so quickly

[Logan-Orr]

Also, this is a weird error, the visuizer is working, but i can not enter any commands because of this infinite loop of error

[onlaj]

Just press CTRL + C

[Logan-Orr]

Am i missing a requirement?

[onlaj]

Are you trying to run script manually now or are those logs from the start-on-boot script?

[Logan-Orr]

Start on boot

[onlaj]

Then don't worry about it. If it's the same case as in the other issue, then it's an error caused by the script trying to run before getting a wifi connection.

It can be temporarily fixed by adding a delay to the script's start.

[Logan-Orr]

Ohhh, it could possibly be from the sudo python3 /home/piano etc. start script that i left in profile

[Logan-Orr]

Yea thats what it was

I have a idea, i was using a synthizer that was for raspi and it was headless, it would be awesome if you could combine the synth with the plv, and have a soundfont menu, the installation was one command and was fast, i can send you a link

Hello, I have created a specific systemctl service in /usr/lib/systemd/system like this one and it works fine on my side:

pi@raspberrypi:/usr/lib/systemd/system $ cat piano-visualiser.service [Unit] Description=Piano Visualizer After=network-online.target Wants=network-online.target

[Install] WantedBy=multi-user.target

[Service] ExecStart=sudo python3 /home/pi/Piano-LED-Visualizer/visualizer.py --display 1in3 Type=simple User=pi Group=pi WorkingDirectory=/home/pi

and then enable it :

systemctl daemon-reload systemctl enable piano-visualiser.service
