[Solved] How reset the displaymanager from lightdm to lxdm after boot

Dear Forum,
embarrassed to say that I made a newbie mistake and downloaded and enabled only the lightdm display manager without its dependencies after full installation of lxdm-gtk3 and all its dependencies.
I disabled the lxdm and enabled the lightdm without thinking of all the related dependency files for the lightdm.
Then I rebooted and am getting this message during boot:

[FAILED] Failed to start Light Display Manager.
See 'systemctl status lightdm.service' for details.
[ OK ] Reached target Graphical Interface.

I have made reboot again on the USB stick but am not experienced enough to reset with "sudo systemctl disable lightdm" and then "sudo systemctl enable lxdm"
Can someone assist?

Thanks in advance!

Petter

Can you switch to a console screen (<ctrl>+<alt>+F3)? From there you should be able to install the greeter.

If you can't do that then use this kernel command line parameter to disable the display manager:

systemd.unit=multi-user.target

Boot into the multi-user.target, log in as root (or your user and then use sudo) and juggle the DMs.

How exactly did you "downloaded and enabled only the lightdm display manager without its dependencies"??
What distro are you using?
