Dev wont launch
rdrivas123 opened this issue · comments
Weird error:
I got a new 4.0 screen, set it up using the standard setup and then did a git pull
It tells me I am up to date, I change to dev (git checkout dev) then run git pull again, it tells me everything is up to date (I figured i would see new files come down)
Now when i reboot I cannot get the app to launch, I have to run: DISPLAY=:0 /usr/bin/python3 /home/pi/music-screen-api/go_sonos_highres.py
This works for me, but once i CTRL+C in the SSH window or if i disconnect, it no longer displays album art.
I cant for the life of me figure out why it wont select the display.
When running it without the display command I get the following:

If you're running from an SSH connection you need to set the DISPLAY environment variable. This is not necessary if you're connected using VNC and open a terminal window from within the GUI.
Does autostart work properly on reboot?
No, no autostart on reboot.
Check the script logs and also ~/.xsession-errors.
No error in xsession, still get this in the app log:

This is a general error saying that it's being launched from outside of the GUI. What does your /etc/xdg/lxsession/LXDE-pi/autostart file look like?
Can you try to change the last line to:
@/usr/bin/python3 /home/pi/music-screen-api/go_sonos_highres.py
It may complain about missing dependencies after that, but this script shouldn't need root permissions.
No dependencies issues, it's working now. As I build more units I will check the info you sent.
This one can be closed.
