如何在login界面不显示某个用户

1）

At that moment this method is not working because of a small bug in lightdm, it should be fixed soon. Please check the bug status before applying this method.

Heres what you want to do:

First, make a backup of your config.

sudo cp /etc/lightdm/users.conf /etc/lightdm/users.conf.bak

Then, you need to edit your config:

sudo nano /etc/lightdm/users.conf

You'll see something like this:

#

# 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

#

[UserAccounts]

minimum-uid=500

hidden-users=nobody nobody4 noaccess

hidden-shells=/bin/false /usr/sbin/nologin

Of interest to us is the part here:

hidden-users=nobody nobody4 noaccess

To hide the username james, just add it like this:

hidden-users=nobody nobody4 noaccess james

Then, reboot your computer and it should be gone.

2）Your option until bug 857651 is fixed is to create the user with uid < 1000
