• Login Bypassing Password Check


    First off, Antergos is simply awesome.

    Now, I’ve been running Antergos for several months now seamlessly. Recently, however, a serious problem began where loggin in to my user account doesn’t ask for a password (and automatic login is off for my account, so this shouldn’t be happening).

    The issue is isolated to my user account. I know this because I created a test account with a password and logging into it works as expected.

    Any ideas of where to troubleshoot?

  • Are you using LightDM? If so, please post the contents of /etc/lightdm/lightdm.conf

    Best Regards,

  • I’m not entirely sure what display manager I’m using. Is there a default one that installs with Antergos? I’m running Gnome, does this mean that I’m using GDM? Do excuse my ignorance… I’m still quite the Linux noob 😞

    Grateful for any continued insight.

  • Perhaps I need to edit or comment out the lines:

      
    autologin-user-timeout=0  
      
    pam-service=lightdm-autologin  
    
    

    If so, how could this file have gotten changed?

  • Hmmm…did you select autologin when you first installed? THat would explain it. In any case you just need to comment out this line:[code:w7blfn8p]pam-service=lightdm-autologin[/code:w7blfn8p]
    It appears twice in the file so make sure they are both commented out.

    Cheers!

  • Did the trick!

    Still don’t know how this line became uncommented though. No, I never selected autologin at any point… strange, right?

    Anyways, many thanks for the help. Antergos is awesome.
