As an alternative to the web interface, you can use VNC with various desktop clients. The main advantage of VNC over the browser is the ability to expand the image to the full screen, as well as complete interception of all keyboard keys. In some cases, VNC will be more responsive than the browser, especially on weak computers.
**Please note: we strongly don't recomment the use of VNC in untrusted networks.** The current implementation uses either weak TLS encryption or no encryption at all (depending on your client). In the latter case, your password will be transmitted over the network in plain text. Unfortunately, this is the reality of the VNC protocol.
1. Switch Pi-KVM filesystem to the read-write mode using command `rw`.
2. Optional: change client's keyboard layout if you're using an non-US keyboard. To do this edit file `/etc/kvmd/override.yaml` (remove `{}` before adding lines):
```yaml
vnc:
keymap: /usr/share/kvmd/keymaps/ru
```
3. Optional: some VNC clients (for example TightVNC) can't use user/password authentication. In this case you can enable passhrases mode in `/etc/kvmd/override.yaml`:
```yaml
vnc:
auth:
vncauth:
enabled: true
```
To set passphrases edit file `/etc/kvmd/vncpasswd`.
4. Enable `kvmd-vnc` daemon. VNC will be available on the port 5900: `systemctl enable --now kvmd-vnc`.
5. Switch filesystem to the read-only: `ro`.
# Configuring the client
We recommend [TigerVNC](https://tigervnc.org) for the better experience.
Here the settings for this client:
* **Compression** tab:
- Choose **Tight** encoding as preferred and color-level **Full**.
