Can't get LightDM to start

I have a Surface 3 Pro with Cinnamon. I'm trying to get a DM installed and LightDM is my first choice

I installed it, and lightdm-gtk-greeter and enabled the service but it won't start.

Initially

lightdm --test-mode --debug

was saying it couldn't find plymouth so I installed it from AUR.

Now it just won't do anything. It shows nothing more than a single cursor at the top left of the screen.

I did have some issues getting the greeter to be recognized since the package didn't install the right .desktop into /usr/share/xgreeters but that was fixed by reinstalling a few times.
Checked /etc/lightdm/lightdm.conf and I've uncommented the session line to

greeter-session=lightdm-gtk-greeter

and the default greeter path has the .desktop file in it now.

Nothing is saved in /var/log/lightdm and also

lightdm --test-mode --debug >> ~/lightdm.log

just saves an empty file but there is something printed to the terminal before it blanks out... so I guess the first step is how can I grab the output from lightdm before it crashes? Or enable logging into /var/log? I couldn't find any setting for this on Google or the man pages.

Thanks.

Re: Can't get LightDM to start

You do not need to enable a service to start it.  Plymouth is not needed unless you want it.
If you ignore test mode and disable lightdm.service so that it will not start on reboot then just start lightdm.service does it work?

Re: Can't get LightDM to start

Ah yes it works when I do what you said. What do you think it could be?

I have

logind-check-graphical=true

uncommented in lightdm.conf so it can't be that.

Re: Can't get LightDM to start

Are there any messages in /var/log/messages regarding lightdm?
