How can I make all my usernames show up in the greeter in Ubuntu 18.04 (desktop)? I've tried various different greeters including
unity-greeter kylin-greeter lightdm-gtk-greeter lightdm-kde-greeter
and played with various settings, but try as I might I cannot get more than 50 users to show up in the greeter. I need all my users to show up in the greeter.
I used the greeter in Ubuntu 14 with over 100 users, no problem. I need to be able to rapidly choose from over 100 logins from the greeter screen. If a hard limit has been introduced, does anybody know where I can reconfigure it, or failing that, where to change ot in the source?
