I've got a patch running on a Raspberry Pi (Stretch Lite, with PD 0.47.1). Generally speaking once the patch is running it all is working fine.

The patch is designed to be left running with the Raspberry Pi on overnight. Each morning when I go to run the patch it doesn't work anymore. If I use SSH to log into the Pi then the patch starts running again instantly.

Is PD, or the Raspi, going to sleep in some way? Is there anything I can do to make sure it keeps running?

Some googling tells me that the Raspberry Pi doesn't really have a sleep mode, it should be able to run continuously. So why is my patch not working until I use SSH?

@amazingrolo No idea, but you are setting the -nogui flag and could set -nosleep as well.
Maybe the patch is running, but a connection, TCP or something else has been dropped.
Are you connecting through Wi-Fi? and the interface is sleeping?
-nogui can cause problems...... that a virtual display..... xvfb .... can solve.

But as your patch was running that is maybe not the problem.

OK well somehow I've fixed it, but I don't know how. I don't think it had anything to do with a sleep mode, or my patch at all. I have a sneaking suspicion that somehow my Raspi got set to require a password on startup? I thought I had set it to auto login, but I switched that again and it seemed to work, so I dunno!
