This question already has an answer here:

How can I remove the Guest account from my admin account? Because there is no use of have a password for the admin account will the guest is open to anyone.


Open /etc/lightdm/lightdm.conf file from your terminal using the following command

gksudo gedit /etc/lightdm/lightdm.conf  

Add the following line


Save and exit the file. Restart the machine.


Open terminal (ctrl+Alt+T) and enter the command

sudo gedit /usr/share/lightdm/lightdm.conf.d/50-ubuntu.conf  

Add the following line to that file as last line, save and close.


Reboot and see.


To disable Guest-session have to edit lightdm.conf. To do,

open lightdm.conf using any text editor like nano, gedit as follows,

Open terminal(Ctrl+Alt+T) and type the following command(For 12.04 LTS),

$ sudo gedit /etc/lightdm/lightdm.conf  

For 14.04 LTS,

$ sudo gedit /usr/share/lightdm/lightdm.conf.d/50-no-guest.conf  

And make the text as following,

[SeatDefaults]  greeter-session=unity-greeter  user-session=ubuntu  allow-guest=false  

Else simply you can type the following command in terminal(Ctrl+Alt+T),

 $ sudo /usr/lib/lightdm/lightdm-set-defaults -l false  

It will automatically do the above said in lightdm.conf.


Also do by opening terminal(Ctrl+Alt+T) and type the following command,

sudo sh -c 'printf "[SeatDefaults]\nallow-guest=false\n" >/usr/share/lightdm/lightdm.conf.d/50-no-guest.conf'  

Save the file and restart the system.
