How to set up auto logon?

[thehamguy1]

In terminal, try navigating to  /usr/share/lightdm/lightdm.conf.d/
Use nano to edit the config and add this line: autologin-user=[username]
Close and save.
See if this does the trick

/usr/share/lightdm/lightdm.conf.d/50-xserver-command.conf

I'm not used to configure systems, I was a guess which conf file I should take out of the 5, but indeed this was the most logical one.

On my Pine64+ 1G there was only one file in that folder, "01_debian.conf" as I recall, so that's the one I edited and things have been fine ever since. I suppose all files in that folder are read as the DM boots, so the added line Luke suggested would be read no matter which file it was in, I'm guessing.
