On my PC, following user shows up on login screen

libvirt-qemu:x:64055:135:Libvirt Qemu,,,:/var/lib/libvirt:/bin/false

This is a user created when installing libvirt. Normally these system added users have uid below 500, that are considered system users and won’t show up. For some reason this user have uid 64055.

root@hon-pc-01:/etc/lightdm# id libvirt-qemu
uid=64055(libvirt-qemu) gid=135(kvm) groups=135(kvm)

Here is the content of my /etc/lightdm/users.conf file

root@hon-pc-01:~# cat  /etc/lightdm/users.conf
# User accounts configuration
# NOTE: If you have AccountsService installed on your system, then LightDM will
# use this instead and these settings will be ignored
# minimum-uid = Minimum UID required to be shown in greeter
# hidden-users = Users that are not shown to the user
# hidden-shells = Shells that indicate a user cannot login
hidden-users=nobody nobody4 noaccess libvirt-qemu
hidden-shells=/bin/false /usr/sbin/nologin
