Hi
I managed to solve everything. Here's how I did it:
- So I installed Krfb (listed in Softwares, the deb version, not the Snap one).
- I configured Krfb with a permanent password (via GUI) and checked the option "Do not remember passwords using KDE wallet ( (it says that it saves the password in the config file, which is not secure, but it's ok for me for this PC)
- I added this line to the krfbrc file located in .config:
startMinimized=true
- I added Krfb in Start Applications in Zorin (just added the krfb command)
Everything works perfectly: the server starts automatically invisibly every time I boot my PC and copy-paste works. When I connect with a client, the icon appears in the notification.
Bye
