Hello,<br><br>Be careful with multi-environment install, because processes installed with XFCE environment will not all released with LXDE. It's a good thing for testing a new environment when you have RAMs, but it's not the best thing to do for saving RAMs.<br>
In the same way, after installing XFCE, I launch the command "top" and I try to uninstall all processes that I don't use (i.e. blueman for bluetooth,...).<br><br>Have a nice day<br><br>
