Autologin for guest account fails

[Thom Mayor]

I researched and read extensively yet cannot find much information or similar reports about lightdm failing to autologin the guest account.

lightdm version is 1.18.2

I am using the lightdm-gtk-greeter and have removed the unity greeter as it did not allow the gtk-greeter to function.

The guest session uses a template defined in /etc/guest-session/skel, which is a symbolic link to user "patron-template" using home directory patronTemplate.

Any other pertinent information can be found in the logs attached.

Thanks for your report. However, it seems to be a support request. Next time, please ask for help at e.g. <http://askubuntu.com>.

Anyway... It's mentioned here:

https://wiki.ubuntu.com/LightDM#Setting_an_Automatic_Login

This is a oneliner to set the desired configuration:

sudo sh -c 'printf "[Seat:*]\nautologin-guest=true\n" >/etc/lightdm/lightdm.conf.d/50-autologin-guest.conf'
