Xvnc is the Unix VNC server. Applications can display themselves on Xvnc as if it were a normal display, but they will appear on any connected VNC viewers rather than on a physical screen. The VNC protocol uses the TCP/IP ports 5900+N, where N is the display number.
### Setup
First of all check if a VNC server is already running or not. Depending on the results you have two options:
1. Use an existing. (Note the Port/Display Number)
2. Stop all and start a new VNC server
```bash
# Check VNC Server directly, lists available with DISPLAY/PORT
vncserver -list
# Check for processes:
ps ux | grep Xvnc
# Kill a VNC Display
vncserver -kill :[DISPLAY]
# Start a new VNC Server
vncserver
```
### Connecting, setting the window manager
Use a VNC client (e.g. the [RealVNC VNC Viewer](https://www.realvnc.com/en/connect/download/viewer/windows/) on Windows, or [Remmina](https://remmina.org/) on any Linux distribution) and connect to `131.130.157.215:[DISPLAY]`.

Connect with a viewer:
1. Hostname: `srvx1.img.univie.ac.at` or `jet01.img.univie.ac.at`
2. VNC Port: `vncserver -list` or `systemctl status --user vncserver.slice`
3. VNC passwort (`vncpasswd` allows to set this on the server)
The VNC server will automatically start a graphical window manager/desktop environment. Details are stored in `.vnc/xstartup`. Your default configuration will load GNOME, and `.vnc/xstartup` will be something like this:
