Description

As discussed on the mailing list:

I'm running a TigerVNC session on the server where Guacamole is installed. If I connect with the TigerVNC viewer there is this nice feature that the remote desktop is automatically resized if the viewer window is resized, like this if offered with RDP already.

Is there a configuration how to achieve this with a Guacamole session as well for my VNC connection?

Historically, this could not be done without corresponding support within libvncclient. This should now be possible through handling the required message type (SetDesktopSize):

Unfortunately my team had to come up with a home baked solution for this about 2 years ago. But it involved hacking up libvnc.

BUT, I think it is feasible to submit a feature request for it because now libvnc recently tagged a new version that includes the message type that guacamole needs to do this:
Tag: https://github.com/LibVNC/libvncserver/releases/tag/LibVNCServer-0.9.13
New message: https://github.com/rfbproto/rfbproto/blob/master/rfbproto.rst#setdesktopsize
