When I try to run xrandr on Ubuntu 17.10 (artful) with xfce 4.12 over VNC I get the error
RandR extension missing I've tried installing libxrandr2 but it's already installed. When I run lxrandr I get the error:
Xlib: extension "RANDR" missing on display ":1.0". I'm using tightvnc as the VNC server. I've tried all the usual sudo apt-get repair things.
When I do
sudo apt-get update sudo apt-get install x11-xserver-utils I'm told that the package is already the newest version.

you have to set display size before starting the vnc like vncserver -geometry 1920x1080 :1
Try installing the development version of randr:
sudo apt-get install libxrandr-dev
