# Ubuntu
https://linuxconfig.org/vnc-server-on-ubuntu-18-04-bionic-beaver-linux


# On server

Enable remote desktop access.

```bash
sudo apt install vnc4server xfce4 xfce4-goodies
```

Disable the vncserver desktop:

```bash
vncserver -kill :1
```

Replace the config in ~/.vnc/xstartup with:

`#!/bin/bash`

`startxfce4 &`

# Arch

Install tigervnc, then run it to set a password:

```bash
vncserver
```

You'll get a session number.

Shut it down with the 'kill' command and the session's number:

```bash
vncserver -kill :1
```

This will forward over port 5900+x where x is the session number.  For the first server, that's port 5901.

# Create a systemd service

```bash
sudo vim /etc/systemd/system/vncserver@:1.service
```

Then enter:

Then enable that service:
