The facts: I had a configuration for sharing my desktop that worked till the recent update of Gnome desktop to use sgnome-shell 3.10. I used to connect to my machine form a Windows one using TightVNC and it worked flawlessly till yesterday (2014-19-1).
Now the connection from the Windows side is failing (full log in pastebin) with this error:
Which digging the log it is:
[ 5872/ 6448] 2014-01-20 12:11:18:247 List of security type is read [ 5872/ 6448] 2014-01-20 12:11:18:247 : Security Types received (1): Unknown type (18) [ 5872/ 6448] 2014-01-20 12:11:18:247 Selecting auth-handler [ 5872/ 6448] 2014-01-20 12:11:18:247 + RemoteViewerCore. Exception: No security types supported. Server sent security types, but we do not support any of their.
The "sharing" part is configured as it should, as you can see here:
The diagnosis: It seems that the update changed the security type to a new one not known by tightVNC (it happened in the past).
The Question: until TightVNC (and the rest of the world) catches up, is it possible to configure the internal VNC server to use the previous Security Type?
