I have an auto-logged in non-sudo user called "screen". I have a passwordless sudo but login-protected user called "support".

I'm pretty sure this was working fine before, somehow maybe the latest dist upgrade broke something...

If I kill X with Ctrl+Alt+Backspace, I get back to the login screen asking for an username, from there, I can login to the support account that should be protected without password! If I logout using the menu, I then get properly asked for a password. But somehow the first login is not protected correctly anymore.

Tried:

  • I tried the answer from this question but sudo gpasswd -d support nopasswdlogin but I get user 'support' is not a member of 'nopasswdlogin'

  • Tried to remove the passwordless sudo %sudo ALL = NOPASSWD: ALL but it did not work either.

Config:

  • my lightdm.conf:

[SeatDefaults] allow-guest=false autologin-user=screen autologin-user-timeout=0 pam-service=lightdm-autologin greeter-hide-users=true xserver-command=X -s 0 -dpms

see if your user is in the "nopasswdlogin" group when logged into that user and typing 

groups

into the terminal.

if so remove the group with

sudo gpasswd -d $USER nopasswdlogin
