Guacamole is already capable, in its current state, of 1) determining browser area/resolution, 2) sending that information on to guacd, and 3) signalling certain protocols to update screen size based on that information. This is automatically performed in the case of Kubernetes, RDP, SSH, and Telnet at connection time (and dynamically during a connection for certain RDP versions). The only one lacking is VNC, and that has nothing to do with Guacamole's inability to collect and pass that information on, but with the lack of at least documented or standardized support within the VNC protocol for performing this operation. As mentioned previously in the thread, several VNC products (RealVNC and TigerVNC, in particular) have come up with ways to implement this within the extensible nature of the protocol, and such a feature could be added to Guacamole, as well (guacd, in the VNC protocol source code). -Nick
