With testing amd64 I installed Xfce a few months ago. I can now say that, for scientific use of the computer, I found Xfce far better than its father, GNOME. First, Xfce does not take possession of the computer. Second, I can run preliminary molecular dynamics with CPU-graphical boards from Xfce. That was not possible from GNOME, which took a lot of RAM and, worse, gradually eated up all RAM. With GNOME I had to run MD without the X-server, a slower doing in trial MD, to prepare the system for the mainframe.
I only have to check whether gchempaint (a drawing tool for small molecules) works with Xfce. That is needed. regards francesco pietra
