Switch between Display Managers
« on: 07. May 2016, 12:06:45 »
Hi everyone

I am running 3.16.7.27-1-MANJARO and I tried yesterday to install another display manager (MDM or SDDM) using https://wiki.manjaro.org/index.php/Install_Display_Managers. Originally I had the LightDM on my system.
After reboot I had no display manager, because for some reason there where two active on the system....and after reboot I got a black login promt screen. I fixed the problem by removing the SDDM or MDM and following the post of FadeMind from here and I successfully returned to my original LighDM.
So here is my question. In case I install another Display Manager to my system what is the proper way to switch between them and not to have a conflict at the next reboot?

This is what I have now:

You need to disable the old one and then to enable the new one, systemd or openrc way.

One example:

Code: [Select]
sudo systemctl disable gdm.service
sudo systemctl enable lightdm.service
