Linux Mint / Ubuntu / Debian Mate Disable Guest Session and Hide Usernames on Lightdm Login screen GUI

sudo vi /etc/lightdm/lightdm.conf.d/70-linuxmint.conf
 

Change this:

[SeatDefaults]
user-session=mate
allow-guest=false

To this:

[SeatDefaults]
user-session=mate
allow-guest=false
greeter-hide-users=true
greeter-show-manual-login=true

 

To see and apply your changes just restart lightdm:

sudo systemctl restart lightdm

 

If you want it to hide your username when the screen is locked (which you probably do since otherwise if you are away from your computer with a locked screen, it would display your username) then follow this guide to disable lock-screen usernames from showing in Linux Mint
