Xpra is known as "screen for X" : its seamless mode allows you to run X11 programs, usually on a remote host, direct their display to your local machine, and then to disconnect from these programs and reconnect from the same or another machine(s), without losing any state. Effectively giving you remote access to individual graphical applications. It can also be used to access existing desktop sessions and start remote desktop sessions.

Xpra is open-source (GPLv2+) with clients available for many supported platforms, and the server includes a built-in HTML5 client. Xpra is usable over a wide variety of network protocols and does its best to adapt to any network conditions.

Xpra forwards and synchronizes many extra desktop features, which allows remote applications to integrate transparently into the client's desktop environment: audio input and output, printers, clipboard, system trays, notifications, webcams, etc.

It can also open documents and URLs remotely, display high bit depth content, and it will try to honor the display's DPI.

Since you were a child you have been training yourself to understand stories.
Don't search for topics, select them

Don't ask "what should I say?" -- this is, what are the important things I can recall with mental effort, won't give us the best results.

Ask - what could I say -- what would I recognise if I saw it in front of me.

Dump your entire knowledge of the subject in any order. To analyse, don't prioritise. Just write. -- pick out the 5 main points, find a story to connect those points -- if something doesn't connect, replace it -- put each bit under those points -- drop anything that doesn't fit under a point
