x11vnc as a Linux alternative to Parsec
Updated
Our verdict
x11vnc is not a good replacement for Parsec if you need low-latency gaming or high-FPS remote streaming. It works for basic remote desktop access over a local network, but suffers from high latency, no built-in audio streaming, and poor responsiveness at distance. While it runs on Linux and supports VNC clients widely, it lacks the performance optimizations Parsec has for real-time interaction. x11vnc suits users needing simple screen sharing on a LAN with minimal setup, but not gamers or those requiring smooth, responsive remote control over the internet.

What works the same
- Both allow remote access to a desktop session
- Support cross-platform clients (Linux, Windows, macOS)
- Can be used over local network and internet
- Provide keyboard and mouse input forwarding
- Run as a service for persistent access
What is different
- x11vnc has no audio streaming support
- Much higher latency than Parsec, especially over internet
- No native gamepad input handling or optimization
- Lacks built-in NAT traversal or easy direct connections
- Maxes out around 10-15 FPS under typical use, not 60+
Opening your Parsec files
Parsec does not generate files for export or sharing in the way that document or media tools do — it's a real-time streaming tool. x11vnc doesn't import or open Parsec data, sessions, or recordings, as both tools operate exclusively during live connections. There is no file interchange between them. Any session data must be handled externally, such as through VNC recording tools or screen capture.
Switching from Parsec to x11vnc, step by step
- Install x11vnc via your distro's package manager (e.g., sudo apt install x11vnc)
- Set a password with x11vnc -storepasswd
- Start x11vnc with: x11vnc -auth guess -forever -passwd [yourpass]
- Connect from a VNC client using the IP and port (usually 5900)
- For audio, set up separate streaming (e.g., PulseAudio over network)
- Use a reverse SSH tunnel or port forwarding if accessing over internet
Key features of x11vnc
- Supports standard VNC protocol version 3.8
- Can share the existing X display or create a new virtual one
- Configurable via command-line arguments or config files
- Supports password authentication and TLS encryption
- Low resource usage suitable for older hardware
- Works with most X11-based desktop environments
- Can be run as a service for persistent access
- Supports multiple clients connecting simultaneously
How to install x11vnc on Linux
sudo apt install x11vncsudo apt install x11vncsudo dnf install x11vncsudo pacman -S x11vncsudo zypper install x11vncFrequently asked questions
Can x11vnc stream audio like Parsec?
No, x11vnc does not support audio streaming. You'd need to set up PulseAudio separately or use another tool for audio.
Is x11vnc suitable for remote gaming?
No. High latency and low frame rates make it impractical for gaming. Use Parsec or Moonlight instead.
Can I connect to x11vnc from Windows or macOS?
Yes. Any standard VNC client on those systems can connect to an x11vnc server.
