Setting up an VNC Server overview

At one time or another almost every system admin has had to setup a VNC server. Here is a brief and haphazard means to accomplish this. For this example we will setup a vncserver that initiated by systemd on a debian derivitive using tigervnc.

For information on how to setup the X-dummy driver for truly headless desktops, please see vnc-xdummy.

Setting up tigervnc-scraping

  1. Create a password using vncpassword as the user you intend to login as.
  2. Make sure the intended user is listed in the file /etc/tigervnc/vncserver.users.
  3. create a config file for vnc by editing/creating ~/.vnc/config with the following syntax.

This was the eventually resolution chosen for setup. As it worked effortlessly, and allowed for good screen resolution and performance.

session=i3
geometry=1920x1080
localhost

  1. Configure X to load libvnc, by adding the following to /etc/X11/xorg.conf.d/10-vnc.conf:
Section "Module"
Load "vnc"
EndSection

Section "Screen"
Identifier "Screen0"
Option "UserPasswdVerifier" "VncAuth"
Option "PasswordFile" "/root/.vnc/passwd"
EndSection

Setting up lightdm to accept and act as a vnc server.

  1. Install the tigervnc-standalone package
  2. Install lightdm and the lightdm-autologin-greeter package.
  3. Open the lightdm configuration file at /etc/lightdm/lightdm.conf
  4. At the bottom of the configuration file you will find the settings for lightdm to run as a vnc server.
  5. Simply uncomment each applicable setting, close the file, and restart the server.

Handling the Failed to create IPV6 VNC socket error

The full error output is: WARNING: Failed to create IPv6 VNC socket: Error binding to address 127.0.0.1:5900: Invalid argument

Right now, fuck if I know. For some reason lightdm is insisting on launching Xvnc on ipv6, which should not be a problem, but appears to be.
