This is due to a change in lightdm 1.7.5 - the guest wrapper is now configurable and the Ubuntu package was not setting it.
The solution is to add a file into /etc/lightdm/lightdm.conf.d to set this, i.e.: $ bzr diff === added file 'debian/50-guest-wrapper.conf' --- debian/50-guest-wrapper.conf 1970-01-01 00:00:00 +0000 +++ debian/50-guest-wrapper.conf 2013-10-27 04:36:08 +0000 @@ -0,0 +1,2 @@ +[SeatDefaults] +guest-wrapper=/usr/lib/lightdm/lightdm/lightdm-greeter-session === modified file 'debian/changelog' --- debian/changelog 2013-10-16 02:54:44 +0000 +++ debian/changelog 2013-10-27 04:36:25 +0000 @@ -1,3 +1,10 @@ +lightdm (1.8.2-0ubuntu1) UNRELEASED; urgency=low + + * debian/50-guest-wrapper.conf: + - Configure guest session wrapper to use + + -- Robert Ancell <[email protected]> Sun, 27 Oct 2013 17:34:20 +1300 + lightdm (1.8.2-0ubuntu1) saucy; urgency=low * New upstream release: === modified file 'debian/lightdm.install' --- debian/lightdm.install 2013-07-16 23:36:16 +0000 +++ debian/lightdm.install 2013-10-27 04:36:08 +0000 @@ -14,3 +14,4 @@ debian/source_lightdm.py usr/share/apport/package-hooks debian/50-xserver-command.conf etc/lightdm/lightdm.conf.d debian/50-greeter-wrapper.conf etc/lightdm/lightdm.conf.d +debian/50-guest-wrapper.conf etc/lightdm/lightdm.conf.d -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1243339 Title: lightdm no longer runs guest session through wrapper To manage notifications about this bug go to: https://bugs.launchpad.net/lightdm/+bug/1243339/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
