How to auto-login in Xubuntu or Ubuntu Server with XFCE?
Solution 1
Type in a terminal (e.g. Xubuntu, Ubuntu Server with XCFE (e.g. Raspberry PI 3):
sudo -e /etc/lightdm/lightdm.conf
(Better than sudo nano /etc/lightdm/lightdm.conf
or sudo mousepad /etc/lightdm/lightdm.conf
, see below the reasoning* - Thank you red_trumpet for the hint)
Add these lines to the file:
[Seat:*]
autologin-session=xubuntu
autologin-user=YourDesiredAutoLoginUserName
autologin-user-timeout=0
You could use e.g. file /etc/lightdm/lightdm.conf.d/autologin-xubuntu.conf, instead, but then you should make sure settings in another file in that directory or in file /etc/lightdm/lightdm.conf do not override it.
For GDM-Users
The config file is located /etc/gdm3/custom.conf
(according to the other answer, please vote Arbuntu's answer up if you found it helpful):
sudo -e /etc/gdm3/custom.conf
Uncomment the following lines (delete the #
) and fill in your user name:
# Enabling automatic login
AutomaticLoginEnable = true
AutomaticLogin = YourDesiredAutoLoginUserName
Extra:
To remove password on resume, right-click the system tray power icon then Preferences. This brings up the XFCE power manager (Alternatively you can navigate to XFCE/Settings/Settings Manager/Power Manager). Click Extended in the left pane. Uncheck Lock screen when going for suspend/hibernate.
The last place is XFCE/System/Users and Groups. If it's set "Password: Asked on login" you can change it, and thereafter, if you logout or switch user, you can get back without entering password.
*Reason for using sudo -e instead of the editor directly:
sudo -e copies the file with user privileges, and opens it with your preferred editor. After saving, the file gets copied back to the original file. In this way, the editor does not obtain root privileges, which is a security improvement. (And if configured correctly, your preferred editor is chosen automatically, which is quite convenient).

Click on Settings --> Users and Groups
Next to Password, click on Change
Click on Don't ask for password on login

Things appear to have changed a bit since the accepted answer was written. Under Xubuntu 16.04 the settings have moved to
/etc/lightdm/lightdm.conf
and they look like this
[Seat:*]
autologin-guest=false
autologin-user=gord
autologin-user-timeout=0
Solution 4
In Ubuntu 20.04 with Xubuntu Minimal Desktop
Open a terminal and paste this, it is the same route that you have put @phil294 in an answer above
sudo nano /usr/share/lightdm/lightdm.conf.d/60-xubuntu.conf
We will find these lines
[Seat:*]
user-session=xubuntu
You just have to paste this autologin with your username (in lowercase)
autologin-user=username
It will look like this
[Seat:*]
user-session=xubuntu
autologin-user=username
To save in the nano editor
Ctrl + o ==> Enter
To exit the editor
Ctrl + x
The next time you log in, the LightDM window will no longer appear

After following @Filbuntu's answer, I had to do two more things to make this work.
First, I thought the autologin-session
parameter was just an alias name so I just put xubuntu
, but turns out it should be a valid xsession name. You can see the ones available as files inside /usr/share/xsessions
. The session name should be the filename without the .desktop
part. In my case I had the following files inside /usr/share/xsessions
:
~$ ls -1 /usr/share/xsessions/
ubuntu.desktop
xfce.desktop
My lightdm.conf
file ended up like this:
[Seat:*]
autologin-session=xfce
autologin-user=foobar
autologin-user-timeout=0
The second thing, I am not sure if it is required or not, but I looked in LightDM's logs (journalctl -u lightdm
) and saw the following line:
pam_succeed_if(lightdm:auth): requirement "user ingroup nopasswdlogin" not met by user "foo"
So to fix it I added my user to this group:
usermod -aG nopasswdlogin foo
Now autologin works as expected.

In spite of setting auto-login in the Xubuntu settings (XFCE/System/Users and Groups) I have to login each time when I start up the computer. How can this be changed?
-
Filbuntu over 9 yearsThanks a lot for the detailed instructions. Somehow this does not work for me. I checked/unchecked and restarted the system several times, but the login screen would still appear. The solution with editing the 10-xubuntu.conf file worked, though.

mTorres over 8 yearsMitch's answer down here was what I've tried, but it didn't work. This trick did, thanks!

Enigma almost 8 yearsThis only removes the need to type a password - it does not enable automatic login.

phil294 about 7 yearsthis configuration can be found @
/usr/share/lightdm/lightdm.conf.d/60-xubuntu.conf
today. -
hanshenrik over 5 yearson xubuntu-installed-lightdm on 18.04, the file
/etc/lightdm/lightdm.conf
does not exist, but if you just copypaste the code to/etc/lightdm/lightdm.conf.d/autologin.conf
(or call it whatever you want .conf), that worked for me :) -
edwardmlyte over 5 yearsOr just create the file
/etc/lightdm/lightdm.conf

jarno over 4 years@Blauhirn that is the system provided configuration; system administrators must not modify that.
