LightDM's guest-account script should disable screen lock universally for guest sessions

[Laércio de Sousa]

Is it feasible to include in /usr/sbin/guest-account script some commands to disable screen lock for guest sessions? It should include several commands, depending on Ubuntu flavour. Examples:

Ubuntu MATE (uses mate-screensaver)
gsettings set org.mate.screensaver lock-enabled false

Xubuntu and others (use light-locker)
gsettings set apps.light-locker light-locker-enabled false
gsettings set apps.light-locker late-locking false
gsettings set apps.light-locker lock-on-lid false
gsettings set apps.light-locker lock-on-suspend false

Can you try lp:~robert-ancell/lightdm/disable-screenlock-mate-xubuntu and see if that works?

[Laércio de Sousa (lbssousa)]

Tested on Ubuntu MATE 15.04 and Xubuntu 15.04. Screen locking is disabled correctly for guest sessions.

Thank you, Robert!

I have the same problem with Ubuntu Mate 18.04 LTS. I have enabled the guest account by creating a file /etc/lightdm/lightdm.conf with the content:

[SeatDefaults]
allow-guests=true

If I switch from the guest account to my normal account and then try to switch back to the guest account, I am locked out of the guest account. It asks for guest account password.

@Sushenjit: This bug report was closed three years ago; please file a new one, and then call the MATE developers' attention to the issue. Maybe MATE is using some other screenlocking mechanism today?

@Sushenjit did you file a bug report?

[Sushenjit Bandyopadhyay (s-bandyo1)]

@Jarno I found the bug report I had filed.

Thanks Sushenjit. I just added a comment on the other bug.

You are welcome Gunner! You are right about the guest feature being deprecated. I stopped using the guest feature soon after filing the bug report.
