I have been using xrdp on the "server" and remmina on the "clients". Both ends worked beautifully "out of the box" (i.e. apt install). Occasionally I might have had to open the firewall for xrdp?

I never see this kind of stuff with XFCE. I run various flavors of Debian that do not go through Ubuntu.

A friend asked me to fix their daughter's desktop and also asked if she could borrow an old laptop to use in the meantime. The desktop was disgusting with food smeared all over the keys and display. I cleaned it up and fixed it and sent it back. My laptop was returned with food smeared everywhere after just a few days. I was stunned.

X is the naughty letter (rated X) in S3XY which is also the four tesla car model letter. 12 year old humor.
