Lightdm broke, have to manual login via bash

Question

I had a problem with Lightdm, each time I put my pc to sleep and wake up, it showed up no user, but asked for password and none worked.

And I don't know if it's dumb, but I also ran locate lightdm | xargs sudo rm -r -f to remove all lightdm files

I uninstalled and reinstalled lightdm with lightdm-gtk-greeter and settings, but now when I boot up, it says just 2 things:

[ OK ] Started Light Display Manager.
[ OK ] Started ACPI event daemon.
       Starting ACPI event daemon...

and it flashes screen like 5 times and it stops. Nothing happens. I have to alt+f1 and manually login + startx to see anything.

How to fix this stuff?

x-0-greeter.log just says: Error writing X authority: Failed to open X authority /var/lib/lightdm/.Xauthority: No such file or directory — VixinG, Oct 30, 2015 at 11:06
Might it be a owner issue? Try typing chown lightdm.lightdm /var/lib/lightdm/ — Prolix, Oct 30, 2015 at 12:18
@VininG The bug above or similar problems can be corrected without reinstalling using: mkdir -p /var/lib/lightdm; chown -R lightdm:lightdm /var/lib/lightdm ; chmod 0750 /var/lib/lightdm with root permission if needed. — Prolix, Oct 30, 2015 at 17:30

Tried everything, even copied the configuration from another computer.

Finally fixed it with writing this into console:

sudo -u my_username /usr/sbin/lightdm --test-mode

it opened the lightdm session in new window and I simply chose to reboot.
