[SOLVED]LightDM issue: Failed to open CK session

!!! Go to #7 for solution

Installed:

$ pacman -Qs lightdm
local/lightdm 1:1.6.0-5 (lightdm)
    A lightweight display manager
local/lightdm-gtk3-greeter 1:1.6.0-1
    GTK+ greeter for LightDM

Started LightDM:

# systemctl start lightdm

But the screen was black, and there was only a cursor.

Log:

# cat /var/log/lightdm/x-0-greeter.log

** (process:1538): WARNING **: Failed to open CK session: GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name org.freedesktop.ConsoleKit was not provided by any .service files

(lightdm-gtk-greeter:1540): GLib-CRITICAL **: g_shell_parse_argv: assertion `command_line != NULL' failed

** (lightdm-gtk-greeter:1540): WARNING **: Failed to open sessions directory: Error opening directory '/usr/share/lightdm/remote-sessions': No such file or directory

Help please. Thank you all in advance.

Re: [SOLVED]LightDM issue: Failed to open CK session

What does your ~/.xinitrc file look like?

I don't have .xinitrc in HOME.

Re: [SOLVED]LightDM issue: Failed to open CK session

the CK error is normal. consolekit is deprecated and is no longer in the arch repositories.

(lightdm-gtk-greeter:1540): GLib-CRITICAL **: g_shell_parse_argv: assertion `command_line != NULL' failed

looks more like an actual culprit. unfortunately, i've never needed to use these desktop managers and, thus, am a bit ignorant about them. did you try

sudo systemctl enable lightdm

and then rebooting instead?

I tried it, and the same result.

A little earlier, I had various DEs installed, and LightDM worked. After removing all DEs but XFCE, I found LightDM failed to work properly.

I tried re-installing LightDM, and found pacman promoted that command failed to execute correctly. This maybe helpful.

Re: [SOLVED]LightDM issue: Failed to open CK session

I've got exactly the same problem with lightdm.

Here's what I've done to break it:

[2013-07-24 18:52] [PACMAN] Running 'pacman -S xfburn'
[2013-07-24 18:52] [PACMAN] installed libburn (1.3.0.pl01-1)

[2013-07-24 18:57] [PACMAN] removed libxfcegui4 (4.10.0-1)
[2013-07-24 18:58] [PACMAN] Running 'pacman -S bashburn'
[2013-07-24 18:58] [PACMAN] installed cdrdao (1.2.3-6)
[2013-07-24 18:58] [PACMAN] installed cdrkit (1.1.11-3)
[2013-07-24 18:58] [PACMAN] installed bashburn (3.1.0-1)
[2013-07-24 19:00] [PACMAN] Running 'pacman -Rsnc bashburn'
[2013-07-24 19:00] [PACMAN] removed bashburn (3.1.0-1)

[2013-07-24 19:00] [PACMAN] installed libkcddb (4.10.5-1)
[2013-07-24 19:00] [PACMAN] installed libmpcdec (1.2.6-3)

[2013-07-24 19:00] [PACMAN] installed cdrdao (1.2.3-6)

I tried removing the newly installed packages (gstreamer0.10-ffmpeg, k3b and its dependencies and cdrdao), reinstalling lightdm and lightdm-gtk3-greeter. But I did not get it working again yet.

Re: [SOLVED]LightDM issue: Failed to open CK session

My solution was remove all packages from "ConsoleKit" that was deprecated and a library related with "Console kit"
