Best Linux remote desktop clients of 2022
Vinagre has a minimal interface that’s very much like Remmina. However, there aren’t nearly as many advanced options behind Remmina’s simple GUI. To connect all you need to do is pick a protocol from the pull-down list and enter the IP address of the remote VNC server.

  • FreeRDP: A Remote Desktop Protocol Implementation
    Https://remmina.org/ The promise behind this sounds like the holy grail of Remote Access. Is it Linux-only for the clients? Or can you use Mac or Windows to reach it? - Source: Hacker News / almost 3 years ago
  • "I need to test something on a Mac real quick", as solved by AWS EC2
    Next up, we need some sort of VNC client on our workstation. I strongly recommend Remmina if you value not spending your time debugging and configuring things. Just select "VNC" from the main connection bar's dropdown, punch in localhost:5900, and hit enter. An authentication screen will pop up: fill it with ec2-user for the username, and whatever password you provided to dscl earlier. - Source: dev.to / almost 3 years ago
