Mike Jumper reopened GUACAMOLE-1196:
------------------------------------
Reopening as the build is failing for some platforms with older versions of
libVNCServer:
* Rocky Linux 8 and 9
* Debian 11 ("Bullseye", "oldstable")
* Ubuntu 18.04 ("Bionic")
The build failure is:
{code:none}

If there are no older alternatives for obtaining and communicating the same
information, I think we'll need some additional configure tests to determine
whether {{rfbClient}} supports dynamic resize.

> 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?
> {quote}
> 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
