I have Zorin Pro running on a few machines. I can screen share between all of them using Remmina and other VNC clients by just enabling native VNC in the 'Sharing' settings section on the server.
The only problem is that when I type the @ character locally, it appears as the Ω symbol (Omega) on the remote server side. This is consistent across all combinations of Zorin machines I am have here.
Any ideas?
