Description of problem: root@localhost:~# ck-list-sessions root@localhost:~# Happens on both F17/F18.
ck-list-sessions will only list sessions if you're using ConsoleKit to track sessions. But we're using logind for that purpose now.

Yes, so perhaps a tool which doesn't work should be removed or at least changed to return an error code. FWIW, the Fedora Feature page states that it should work when ConsoleKit is installed: Also verify that ConsoleKit continues to work as expected when it is installed. This can be done e.g. with the help of ck-list-sessions http://fedoraproject.org/wiki/Features/ckremoval
2 prerequisites for ck-list-sessions to work. * ConsoleKit-x11 rpm installed * login manager configured to use ^^ for the latter, login manager either needs to support CK natively (none do these days, afaik, it's largely deprecated), or via pam_ck_connector.so , /etc/pam.d/lightdm contains: -session optional pam_ck_connector.so for example. If you want this to work, install ConsoleKit-x11 and configure your login manager as suggested.
