I have a rpi2 running the latest raspbian image with Pixel desktop. I enabled ssh and vnc in raspi config. Rpi is connected to my home network over ethernet and has an IP address. I'm also able to ssh into it from my Linux laptop. However, I cannot connect to the now running vnc server. I'm using Remmina remote desktop client from my Ubuntu laptop.
The error message says something like "connection refused. authentication scheme is not known".
As I understand, after enabling VNC server from the raspi-config GUI, connections from clients should just work. Anyone else seen this? Kindly help.
Thanks and regards,
P.S. I have used RealVNC vnc server on my rpi before (earlier raspbian versions) and it worked just fine.
