I used to be able to connect to my Gnome 3 desktop from a Windows machine with a VNC client. But after an upgrade (on the Linux side) a while ago, it quit working. When I attempt to connect, all I can get is a message saying "No matching security types" or "No supported authentication methods!" (depending on which client I try).
In Gnome 3, I've turned on Screen Sharing under Settings > Sharing. Under that, I have Remote View on, Remote Control on, Approve All Connections on, Require Password off. I'm running Arch Linux with vino 3.8.1.
On the Windows side, I've tried TigerVNC 1.0.1 & 1.2.0 and UltraVNC 220.127.116.11.2.
How can I get this working?
