-------------------------------------------------------------------

I did not get this issue on ubuntu 16.04 with lxde, but I cannot resize using tightvnc and xrandr dynamically. xrandr is missing RANDR extensions, if I need a different resolution dynamically. 

I do have the same issue with centos 7 and tiger vnc. If there was a workaround that would be great. I need to be able to change resolutions accross multiple screens as a user requires in HTML 5. 

It would be great if this could be fixed!

> Connecting to certain VNC servers such as Ubuntu Desktop (all versions I have ever run) and a CentOS based Browser Docker ([https://hub.docker.com/r/consol/centos-xfce-vnc/]) cause frequent TLS errors and consequently disconnections. The errors in the log are as follows:
> {noformat}
> Oct 12 14:54:59 2004ff6050af guacd[8440]: Error reading from TLS: The TLS connection was non-properly terminated..
> Oct 12 14:54:59 2004ff6050af guacd[8440]: read (4: Interrupted system call)
> Oct 12 14:54:59 2004ff6050af guacd[8440]: Error handling message from VNC server.
> Oct 12 14:54:59 2004ff6050af guacd[8440]: Internal VNC client disconnected
> {noformat}
