Thanks. I am testing XFCE desktop for now. A brief comment on XFCE experience. The starting size of Xorg process under XFCE is ~100-130 MB, but after 10 days of usage with mostly Firefox & terminal windows (multiple windows for each app, and sometimes pdf viewer [atril]) it grew to 270-300 MB. I have some data collected by xrestop, ps, if you want it. Let me know what kind of data would help.
In a prior session where I was still using LibreOFfice (again, with multiple windows, but nothing is a huge document or complicated doc with lots of graphics), the memory usage grew to over 800 MB usage. And xrestop indicated libreoffice was consuming nearly 200 MB of pixmap memory just before I closed it! Any direction to help narrow down the source of large memory consumption would be appreciated.

Here is an example of memory usage of Xorg as a function of time.

I don't know exactly which software is responsible to cause this problem, so I started out with xorg server.
