Re: Mint Cinnamon with a default login

Thanks, Rusty.

I had not found the first link you offered, which seems right on target. I did find a lightdm.conf file, that’s the one I said had just one entry and it was not relevant. Now I have some pointers to possible settings I can try.

I’m not near the PC right now, but it’s clearly MINT 18 and was supposedly the latest, so presumably 18.3.

This system didn’t have an mdm.conf file, in fact “find” didn’t find anything on the disk about “mdm”. Online I saw references to it, but didn’t find the setting that I may need, "AutomaticLoginEnable=False”, which I’ll keep in mind as a backup.

Stephen: You mentioned a live DVD, thanks for the nudge. Since I am now supporting two Mint systems besides my own desktop, I think it’s time to learn how to make a USB backup boot. We do have the “tom” account doing the usual sudo and admin things, but I’ve been afraid to wipe out the “user” account because the auto-login might hang up looking for it. I’d thought about a live DVD as insurance, but your mention has pushed me into getting it done.

Thanks all,
Victor

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 athttps://forums.linuxmint.com/viewtopic.php?t=252967 <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 athttps://unix.stackexchange.com/questions/180565/how-to-autologin-as-root-to-mint-17-1 <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, seehttps://unix.stackexchange.com/questions/381785/how-do-i-enable-auto-login-in-mint-18 <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 (seehttps://unix.stackexchange.com/questions/45573/how-to-disable-auto-login-in-linux-mint <https://unix.stackexchange.com/questions/45573/how-to-disable-auto-login-in-linux-mint>)

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
