I have been running through methods of installing and configuring lightdm as according to the Arch Wiki (In order to try out the available cinnamon desktop), but I have had no luck in getting the program running.

I had installed the 'Lightdm','lightdm-gtk3-greeter', and 'cinnamon ' packages to start with.

After all configuration, I get this:

[FAILED] Failed to start light display manager. See 'systemctl status Lightdm.service' for details. Stopping light display manager... [OK] Stopped light display manager. Starting light display manager..

And then after that, the process repeats, until the last copy ends with:

[OK] reached target graphical interface

And the screen freezes.

Help?

  • As mentioned in your error message, you have to check the return of the systemctl status lightdm.service command and also the /var/log/lightdm/lightdm.log file

  • @Nicolas The problem that seems to be going is this: DEBUG: Seat: creating greeter session DEBUG: Seat: Failed to find session configuration lightdm-gtk3-greeter DEBUG: Seat: Failed to create Greeter session. To start, what might that mean? (My guesses are that the greeter may need configuration, or the lightdm configuration is missing options, so on) Jun 20 '14 at 17:57
  • Could you check that you have a /etc/lightdm/lightdm-gtk-greeter.conf file with the good access rights.

I too had lighdm, lightdm-gtk3-greeter, and cinnamon installed and experienced the same errors.

In my case, I solved this by commenting out a line in /etc/lightdm/lightdm.conf I had added to enable the gtk3-greeter:

#greeter-session=lightdm-gtk3-greeter

After rebooting, lightdm started successfully. I am not sure what greeter is in use when none is specified in the config, but I am guessing it is not the gtk3-greeter.
