This bug was fixed in the package lightdm - 1.18.2-0ubuntu1 --------------- lightdm (1.18.2-0ubuntu1) xenial; urgency=medium
* New upstream release: - Don't quit on SIGUSR1, SIGUSR2 or SIGHUP (LP: #960157) - Use MIR_SERVER_HOST_SOCKET instead of MIR_SOCKET to report compositor socket to sessions. This used to work but no longer works in Mir 0.21 (LP: #1583624) - Use only a single compositor on xlocal seats (LP: #1594229) - Fix Mir greeter log filename having "(null)" in the name (LP: #1590582) - Set XDMCP hostname field in to system hostname or configured value (LP: #1578442) - Improve XDMCP IPv6 address selection (LP: #1575200) - Allow fcitx and mozc to run in guest session (LP: #1509829) - Fix uninitialized memory errors * debian/lightdm.dirs: - Ensure user configuration directories /etc/lightdm/lightdm.conf.d and /etc/guest-session exist * debian/guest-account.sh: * debian/guest-session-setup.sh: - Source prefs.sh as privileged user to allow user modification (LP: #1581853) -- Robert Ancell <robert.anc...@canonical.com> Tue, 21 Jun 2016 12:49:01 +1200 ** Changed in: lightdm (Ubuntu Xenial) Status: Fix Committed => Fix Released -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to lightdm in Ubuntu. https://bugs.launchpad.net/bugs/1581853 Title: Source prefs.sh as privileged user to allow user mods Status in lightdm package in Ubuntu: Fix Released Status in lightdm source package in Xenial: Fix Released Bug description: [Impact] including [Test Case] The Ask Ubuntu question <http://askubuntu.com/q/771080> called my attention to a regression in 16.04 as regards the possibilities for the system owner to configure the guest account. Up to 15.10 you can put e.g. this line in /etc/guest-session/prefs.sh: adduser $USER somegroup But if you try that in 16.04, the guest session won't launch. The explanation is that after the reorganization of the guest session code in 16.04, prefs.sh is sourced by /usr/share/lightdm/guest- session/setup.sh, which is not run as root. The linked merge proposals restore the previous behavior by letting prefs.sh be sourced by /usr/sbin/guest-account again. [Regression Potential] Low.
