This is a fresh install of Lubuntu 16.4.6 using the iso from the official download site. MD5sum checks.
I disabled the “ask for password” option and also included the only user in the “no login password” group.
It still shows the login dialog where I have to click on “unlock” for it to login.

This is inconvenient because I use this PC as a printer server for 2 printers and there’s no monitor or keyboard connected to it.
Is there any way I could solve it?
Thanks in advance.
