Public bug reported:
Steps to reproduce bug:
1) Install xubuntu or mint xfce
2) download and set lightdm as desktop manager
3) sign in to a guest session and either close your laptop lid or allow
timeout to start screen lock
Why this is a bug:
xscreensaver will not accept a blank/null password, and with a
blank/null password assigned to the guest session, the xscreensaver
client will not allow the user to continue their session or login as a
new user (because you cannot login as a new user as xscreensaver does
not support lightdm for this feature.
Why this is severe:
when xscreensaver locks the guest user out of their session, all other
users are similarly locked out. Being so locked out, the computer most
be hard-reset/rebooted and any documents and processes not saved prior
to the guest session being logged in is lost.
Why this is a lightdm bug:
Because lightdm is not setting the gconf setting to disable the lock
screen feature for guest sessions
Why this is a xscreensaver bug:
xscreensaver does not support any dm other than mdm
