Hello again, Thanks to your suggestions, I decided to 1. Replace GDM with LightDM 2. Install LXDE as lightweight DE The installation was easy and I am really glad of the RAM performance obtained (I suppose GDM was the real resource hog). These is only one small desire that is still unexpressed for me: I both have mutter and openbox locally installed and I would like to use only mutter (looks much better) when using LXDE. The problem is that I have literally no idea of how to set up its keys; from its man, I should change them from the Control Center, that is not present in LXDE (it's GNOME stuff) and I am not sure of which GNOME settings services I should execute to make it work. If anyone has any tips, please speak ahead! Thanks again to all, anyways :) -- Giovanni Santini My blog: http://giovannisantini.tk My code: https://git{hub,lab}.com/ItachiSan My GPG: 2FADEBF5
