Hello samhain !
It's my first post here.I use your OS since about one month now.Runs great but it uses a lot ram at start up ( about 800MB  with htop ).Right now i'm under excalibur XFCE where i installed TDE; and under TDE the ram used is about 460MB at start up.Xlibre seems to consume more ram than Xorg.
Best regards,
Amol
