Oh, I see. It's a bit of a naming problem, for mostly historical reasons. For all intents and purposes of this thread, X11 is equivalent to Xorg. You have many Xorg packages on your system, if that is what provides the graphical interface.

Generally speaking - I think you lack some basic knowledge of GNU/Linux generally and what a server is specifically. If you still don't realize that ssh consists of 2 parts, one for the server, one for the client, with separate configurations. If you need to be told to read man pages, or provide FULL command output. This is going nowhere.

There were no comments. I ran the script and it works. Login still goes to VPS terminal. In VPS terminal I type firefox, then GUI, mouse, keyboard work on VPS. Remote system is slow, but that is expected. Only one mouse cursor is visible and it does not change. On my local system, am I running remmina or x11vnc? In VPS terminal I type gnome, but it is not found, how to start desktop? Now can someone help with firewall?
