I had seen a post that if you vnc to server:0 instead of to server:5901, then you can share/control the current X session runnng on an OES2 (kde) server.
It was working receently, but now I can only vnc to a new session on :5901 , on two different servers.
I cannot vnc to the :0 current X session on either server.
Have also tried from a browser to server:0, no joy, but to server:5801 is ok.
What to check ?
