Two issues here:
1) I recommended it as a 20 second diagnostic test, after which you
restore the original situation.
2) As a permanent solution, as opposed to a diagnostic test, renaming
lightdm and putting your desired Window Manager in .xinitrc might
preclude your using certain Window Manager/Desktop Environments as
intended. I know gdm is needed for Gnome. Don't believe me, take it from
The Man himself:

On Debian Wheezy and Manjaro, I've been able to run Xfce without any
kind of display manager.
