Bug Description

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

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?

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.
