Description of problem: I have installed LightDM on a Fedora 18 Minimal X Installation and activated it using systemctl enable lightdm.service. Sadly it does not start on boot. systemctl status lightdm.service lightdm.service - Light Display Manager Loaded: loaded (/usr/lib/systemd/system/lightdm.service; enabled) Active: inactive (dead) Docs: man:lightdm(1) CGroup: name=systemd:/system/lightdm.service When I start it manually from console using systemctl restart lightdm.service it works fine. I have tried to find out more in the logs but only found: /var/log/lightdm/x-0-greeter.log (lightdm-gtk-greeter:1032): GLib-CRITICAL **: g_variant_get_type: assertion `value != NULL' failed (lightdm-gtk-greeter:1032): GLib-CRITICAL **: g_variant_type_is_subtype_of: assertion `g_variant_type_check (type)' failed (lightdm-gtk-greeter:1032): GLib-CRITICAL **: g_variant_get_type_string: assertion `value != NULL' failed ** (lightdm-gtk-greeter:1032): WARNING **: Unexpected accounts property type for XHasMessages: (null) (lightdm-gtk-greeter:1032): GLib-CRITICAL **: g_variant_unref: assertion `value != NULL' failed and /var/log/messages Sep 27 14:39:27 localhost dbus-daemon[472]: dbus[472]: [system] Rejected send message, 2 matched rules; type="method_call", sender=":1.26" (uid=995 pid=1109 comm="/usr/sbin/lightdm-gtk-greeter ") interface="org.freedesktop.DBus.Properties" member="GetAll" error name="(unset)" requested_reply="0" destination=":1.19" (uid=0 pid=1007 comm="/usr/sbin/console-kit-daemon --no-daemon ") Sep 27 14:39:27 localhost dbus[472]: [system] Rejected send message, 2 matched rules; type="method_call", sender=":1.26" (uid=995 pid=1109 comm="/usr/sbin/lightdm-gtk-greeter ") interface="org.freedesktop.DBus.Properties" member="GetAll" error name="(unset)" requested_reply="0" destination=":1.19" (uid=0 pid=1007 comm="/usr/sbin/console-kit-daemon --no-daemon ") Sep 27 14:41:06 localhost lightdm[1089]: ** (process:1268): WARNING **: Failed to open CK session: GDBus.Error:org.freedesktop.ConsoleKit.Manager.GeneralError: Unable to get information about the calling process
Is lightdm the only DM on this system (besides gdm perhaps)? Otherwise, https://fedoraproject.org/wiki/Features/DisplayManagerRework#How_To_Test suggests you need to: systemctl enable --force lightdm.service
lightdm is the only dm installed on that machine, so forcing does not help.
Created attachment 618259 [details] dmesg output with systemd debug information
Missed to systemctl --force enable graphical.target Sorry for the noise.
