I have just created a bootable Linux USB and added three accounts: My Account, My brothers account and a Guest account. every time i boot Linux up it used to log me straight into the "mint" default account. I changed it so it would log into mine hoping that a login screen would show up since all the others accounts require a password. But it logs me straight into mine. I would like a logon screen to show up when i boot into Linux but this doesn't occur. I can switch users after it log's me in to another and it shows the logon screen there but not when i first boot it up. Is there is a way for a logon screen to show up after booting into Linux Mint 19 on a bootable USB? Also would there be any way to disable the "mint" account. I am using Linux mint 19 Cinnamon.

  • What shows up in your System Settings -> Administration -> Login Window? (Or if no login window, then mdm or lightdm, etc) – Xen2050 Oct 21 '18 at 12:22

On install there is an option when creating your username to autologin or manual login. To change this after install you need to:

menu --> Administration --> Login Window

Click the "Users" at the top, then delete the user that is in the "Username" box under Automatic Login. Close and reboot and you should be presented with a list of users to login with.

  • there is no mdm file but there is a lightdm file. in it it says: [SeatDefaults] allow-guest=false allow-login-guest=false autologin-user=mint autologin-user-timeout=0 [seat:*] greeter-show-manual-login=true greeter-hide-users=true atologin-user=dextron. – 26099 Oct 22 '18 at 2:27
  • I cannot edit the lightdm file even when I’m an admin – 26099 Oct 22 '18 at 5:49
  • Edited answer above. Did that work for you? – Taslack Oct 22 '18 at 5:59
  • I have Linux on a live USB so I’m assuming I actually have to install it on a USB to use Linux properly – 26099 Oct 22 '18 at 10:01
  • Yes, changes will not persist from reboots on a live USB. Best way for you to do this is to do a full install of Mint on to a USB drive. There are many ways to do this, one is to dd the image to a USB drive and another is explained here forums.linuxmint.com/… – Taslack Oct 22 '18 at 12:05
