Autologin not working after last update

gdm3 (Ubuntu)

Bug Description

How to reproduce:

Install Ubuntu 18.04 Desktop (LTS) using ubuntu-18.04.2-desktop-amd64.iso

Configure a user with autologin enabled (at installation time).

Reboot several times in order to verify that autologin feature is working propperly.

Apply the latest updates using the Software updater tool.

Restart and Autologin is not working anymore.

To solve it i just donwgrade the GDM3 package from:

gdm3 3.28.3-0ubuntu18.04.4


gdm3 3.28.0-0ubuntu1

Using this command:

sudo apt-get install gdm3=3.28.0-0ubuntu1 libgdm1=3.28.0-0ubuntu1 gir1.2-gdm-1.0=3.28.0-0ubuntu1

And I setted the autologin again (already setted to ON) via Settings -> Details -> Users

I realized the solution i proposed works just once (in the next reboot/poweroff). After that, it doesn't work anymore. No matter ir you apply again the autologin setting it will not work anymore so it's not a solution.

I reviewed the list of updated packages in order to find one to blame but its to large (about 400) in order to blame just gdm3 for that bug.

There are no changes between the files on the two version of the gdm3 package: 3.28.3-0ubuntu18.04.4 and the 3.28.3-0ubuntu. All the files has the same md5sum so the the problem is somewhere else.

The best solution I've found is to uncomment the "Timed login" options on the custom.gdm as shown here

# Enabling timed login
TimedLoginEnable = true
TimedLogin = username
TimedLoginDelay = 10
