Is this mint 17 or mint 18? In fact, is it 17, 18, 18.1, 18.2, or 18.3?
If you have a /etc/lightdm/lightdm.conf file, then set it to something like [Seat:*] #autologin-guest=false #autologin-user=john #autologin-user-timeout=0 (I think. Or that might turn it on, not sure. Found that info at https://forums.linuxmint.com/viewtopic.php?t=252967) The other file to look for is /etc/mdm/mdm.conf, where you make sure AutomaticLoginEnable=False. (I found that at https://unix.stackexchange.com/questions/180565/how-to-autologin-as-root-to-mint-17-1, but note that this is for turning it ON, you want to turn it off. (This is for mint 17.1)) Again, if you’re using mint 18.2, see https://unix.stackexchange.com/questions/381785/how-do-i-enable-auto-login-in-mint-18, which gives even better info about how to make sure you’re running the display-manager that the information is applicable to. You also might need to look at /etc/mdm/mdm.conf (see https://unix.stackexchange.com/questions/45573/how-to-disable-auto-login-in-linux-mint) Rusty From: PLUG-discuss [mailto:[email protected]] On Behalf Of Victor Odhner Sent: Wednesday, June 20, 2018 10:38 PM To: Main PLUG discussion list Subject: Mint Cinnamon with a default login A vendor loaded Tom's new PC with Mint Cinnamon. It powers up without authentication to a default user account. How do we disable that? The details: It was set up with one temporary admin user, named “user”, with password “password.” So we set up the “tom” account, with admin status, and then made “user” an ordinary user with its permissions turned off, and a serious password. We ran fine as “tom”, but when we shut down and restarted, it came right up as “user” without authentication. We can log out of the “user” session and we get the login dialog so we can get to the “tom” account. We could remove “user,” but I thought it might hang up looking for that account. I did some web searching and they referred to two config files to be adjusted, but one didn’t exist and the other had only one line which wasn’t relevant to the issue. Any suggestions? Thanks, Victor
