Hi Mike,

     the following solved the problem:

 > citation DRC (TurboVNCusers) 
-------------------------------------------------

I generally recommend noVNC over Guacamole for HTML 5 viewing, and I'm
trying to secure funding to add the RFB flow control extensions to noVNC
so that it will perform better on high-latency connections (it will
still never be as fast as Java or native, however.)

As far as Guac, I'm not sure why it's reporting 2.0 as the VeNCrypt
version.  It may mean 0.2, which is the version of VeNCrypt that we
support (also the version that TigerVNC supports.)  To globally disable
VeNCrypt in the server, edit /etc/turbovncserver-security.conf and set
permitted-security-types such that it only allows non-VeNCrypt security
types.  Example:

     permitted-security-types = VNC, OTP, UnixLogin, None

will make the server behave like TurboVNC 2.0.x.  If you want to do this
just for one instance of the server, then you can start it with an
appropriate -SecurityTypes argument, such as:

     -SecurityTypes VNC,OTP,UnixLogin,None
