I have recently re-installed an Ubuntu 18.10 system and installed cinnamon with:

sudo apt-get install cinnamon

as well as lightdm, and also proceeded to purge unity and gdm3.

I have a similar issue to Unable to log in to Cinnamon session 18.04. After I type in my password there is a pause, the screen goes black, and then returns to the original log in screen.

However unlike the linked issue, gnome-user-share is not installed. Instead, I found that reinstalling snapd after I had previously purged it allowed me to login to Cinnamon. This is an oddity to me since previously I was using an 18.04 system upgraded to 18.10 where snapd was uninstalled in 18.04 and Cinnamon functioned just fine.

These are the contents of .xsession-errors.old: https://pastebin.com/6uPZZwi, the only error being:

(process:1076): GLib-GIO-ERROR **: 20:42:00.980: No GSettings schemas are installed on the system

These are the contents of my custom lightdm config in /etc/lightdm/lightdm.conf.d/10-autologin.conf :

[Seat:*]
autologin-guest = false
autologin-user = polly
autologin-user-timeout = 0
user-session = Cinnamon

[SeatDefaults]
allow-guest = false

Is there any way to recognize the connection between snapd and cinnamon?

sudo apt install --reinstall gsettings-desktop-schemas solved it for me. Seems typing out your question makes it easier to actually google it.

Another possibility is that somehow the ownership of /home/user/.Xauthority has been changed.

sudo chown user:user ~/.Xauthority
