lightdm_greeter_error: Unable to determine socket to daemon

[ghost]

Hello,

Specs:
OS: ubuntu 18.04
WM: i3-gaps

I have managed to install successfully through downloading and manually installing as instructed in the wiki and I have all the required dependencies and then I included X-LightDM-Allow-Greeter=true in my desktop file.

when I try to start it using web-greeter I get this error:
2018-09-27 13:16:07 [ DEBUG ] objects - objects.py:124 : _setup_logger | Logger is ready. 2018-09-27 13:16:07 [ DEBUG ] app - app.py:57 : _wh_load_config | Try load config using key: WebGreeter 2018-09-27 13:16:07 [ DEBUG ] window - window.py:78 : _initialize | Initializing Main Window 2018-09-27 13:16:07 [ DEBUG ] __main__ - __main__.py:64 : __init__ | Web Greeter started.

I have enabled logging and the log files are empty.

if there's any more info you need I'd be happy to provide it.

Thanks in advance.

Hey, I'm running Ubuntu 18.04 with i3 (not gaps) and I'm getting exactly the same error!
