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

It did not work. As per your instruction I added a line to "sudo nano /usr/share/lightdm/lightdm.conf.d/01_debian.conf", but still my "dont ask logon password" check box still grayed out.

What should I do now?

Instead of [username] use the actual user. So for instance, for Debian that would be: autologin-user=debian

Thanks. I already did that. see below.

[SeatDefaults]
greeter-session=lightdm-greeter
greeter-hide-users=true
session-wrapper=/etc/X11/Xsession
autologin-user=[pine64user]

I have kept it same login. I also tried with changing to new name as "coolnine98" name but still no luck so I revert back to default username=pine64user.

Remove the brackets around "pine64user" and that will (I hope) solve it. The brackets were supposed to call attention to the fact that what's inside them is a placeholder, not the actual wording.

Oh, and that checkbox will still be greyed out. It is on mine too. But that's not a problem because the system boots up fully without asking for a password once you've got that added line configured right.
