How to enable autostart of the display manager?

edit

Hello,

I just installed Fedora 23 in my virtual machine. I did so by using the netinstall with a minimal system. Xorg works as well as fvwm. I wanted to install lightdm to autostart my fvwm desktop, but somehow the lightdm service does not start.

I installed the system-switch-displaymanager and ran it with the parameter lightdm. It created a symlink in /etc/systemd/system folder which points to /etc/lib/systemd/system/lightdm.service.

I also tried to run systemctl enable lightdm.service but it doesn't start either.

What can I do now?
