Thanks Julien, it's still in the deb in /usr/lib/lightdm/lightdm/gdmflexiserver, the hack to inject that dir to the PATH seems to have broken though, is that your issue? What screensaver do you use? Marc Deslaurier fixed gnome-screensaver yesterday to use the lightdm dbus interface when available that should avoid relying on the gdmflexiserver hacks

Correct, I didn't see it yesterday in the .deb
I can confirm it's still not in the PATH, which break LXDE session manager (lxsession). It can't see gdmflexiserver, and probably can't launch it.

summary: - gdmflexiserver is gone
+ gdmflexiserver not in the PATH

I'll make the appropriate changes in lxsession to make it work again. Having gdmflexiserver back in the PATH would be nice, as lxsession and gnome-screensaver are probably not the only packages affected and relying on this mechanism.

Does a change still need to be made in lxsession, or does the lightdm change fix this bug completely?

lxsession still needs to implement the Dbus method over the gdmflexserver method. It's a work in progress upstream.
