After logging into ubuntu dde 20.04 (where one type in the passwoed), it takes a long time (35-45s) to launch the deepin desktop. I read somewhere that deepin hogs a lot of memory. A check with my system monitor gives a 70% usage of my 4gb RAM with just the system monitor and firefox running. My laptop is an hp pavilion g4 series notebook with an i5 intel processor. Is it my laptop's or the DDe's fault?
