I have a minimal install on my Pi Zero using DietPi.
I now want to add RealVNC to it so I have followed the instructions at their site: https://www.realvnc.com/docs/raspberry-pi.html
I installed it with
sudo apt-get install realvnc-vnc-server
The I had to install some missing dependencies
sudo apt-get install xauth x11-xserver-utils libgtk2.0-0
Now I get an error in the log:
Starting session: /etc/X11/Xsession Session terminated with return code 1 FreeFontPath: FPE "/usr/share/vnc/fonts/" refcount is 2, should be 1; fixing. <13> 2016-12-05T05:14:35.436Z DietPi Xvnc: ServerManager: Server stopped XIO: fatal IO error 11 (Resource temporarily unavailable) on X server ":1" after 78 requests (78 known processed) with 29 events remaining.
