I have been reading about LightDM. Ubuntu and Debian use it as their default. GDM3 is default in LMDE xfce. Would there be a benefit to changing?
I looked at LMDE in Virtualbox with gdm3 and lightdm. Lightdm takes 3.9 megabites of memory and gdm takes about 10.5. Both can do auto login and Lightdm is independent of desktop enviroment. I have seen this site which hints there is some inferior power settings for Lightdm. They mention power saving when a laptop lid is closed. But xfce power manager would command this, not the display manager correct?
Other than a tiny amount of memory would there be any other advantages?
