/etc/lightdm
├── lightdm.conf.d
│   └── guest.conf
└── users.conf

---

总结

方法一

创建/etc/lightdm/lightdm.conf文件，并加入下面的配置。

[Seat:*]
allow-guest=false

方法二

在/etc/lightdm/lightdm.conf.d目录下创建任意的以.conf结尾的文件（*.conf）。并加入以下配置。

[Seat:*]
allow-guest=false

---

无效方法

修改/etc/lightdm/users.conf文件

以下两种加入配置的方法均失效。

#
# 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
#
[UserList]
minimum-uid=500
hidden-users=nobody nobody4 noaccess
hidden-shells=/bin/false /usr/sbin/nologin
[Seat:*]
allow-guest=false

与

#
# 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
#
[UserList]
minimum-uid=500
hidden-users=nobody nobody4 noaccess
hidden-shells=/bin/false /usr/sbin/nologin
allow-guest=false

在/etc/lightdm目录下创建非lightdm.conf文件

只有创建lightdm.conf名称的文件并加入配置才有效，一旦改名便失效。
