Download the Latest Version of TurboVNC

TurboVNC is a high-speed version of VNC derived from TightVNC. It features a different type of Tight encoding optimized to maximize performance for graphics-heavy applications like VirtualGL, video apps, and image editors, while still delivering excellent performance for other application types.

Originally, TurboVNC branched off from TightVNC 1.3.x but has developed its own features such as:

• The current version of TurboVNC includes a modern X server code base (based on X.org).
• A high-performance, cross-platform VNC viewer with session management capabilities.
• Unique features tailored specifically for visualization applications.
• TurboVNC uses only 15-20% of the CPU time that TightVNC 1.3.x uses in these scenarios.

Some of these features are not available in any other open-source remote display solutions for Linux/Un*x.

TurboVNC Performance and Compression

Downloading the latest version of TurboVNC, alongside VirtualGL, offers a complete solution for remotely displaying 3D applications with interactive performance without overloading the CPU, GPU, or operating system.

TurboVNC is the result of extensive research, where the performance of various TightVNC codec permutations was measured at a low level against a variety of captured RFB sessions simulating real-world 2D and 3D application workloads. TurboVNC's encoding methods have been adopted by TigerVNC, libvncserver, and others.

Features of TurboVNC

Downloading the latest TurboVNC version allows you to enjoy several unique features, including:

• Precise control over JPEG image quality and chrominance subsampling level.
• Client-side double buffering to reduce tearing artifacts in 3D and video applications.
• Flexible and configurable support for full-screen/multi-screen setups.
• Full IPv6 protocol support.
• Advanced flow control and continuous updates. This allows clients to receive framebuffer updates without specifically requesting them, which can significantly improve performance on high-latency connections.
• Authentication using one-time passwords or Unix login credentials. Access control lists can be used to share VNC sessions with specific users only.

Highlights of the Latest TurboVNC Download

• TurboVNC allows setting global security/authentication policies for a specific server machine.
• Multithreaded Tight encoding.
• The "lossless refresh" feature allows viewers to request a lossless copy of the current screen image, which is useful in cases where image quality is critical but the network is too slow to support sending a high-quality image for every frame.
• Lossless refreshes can be performed manually by pressing a specific shortcut key, or the TurboVNC server can be configured to send a lossless refresh automatically if the user stops interacting with the application for a certain period.
• A high-performance Java viewer, deployable using Java Web Start. This viewer is based on the TigerVNC Java viewer but includes several additional features, most notably the ability to accelerate JPEG decompression by calling libjpeg-turbo via JNI. This gives the TurboVNC Java viewer performance levels similar to the native TurboVNC viewer.
• On "modern" hardware, TurboVNC can stream more than 50 megapixels/second over a 100 Mbps local network with virtually lossless image quality. TurboVNC can stream between 10 and 12 megapixels/second over a 5 Mbps broadband connection with low (but usable) image quality.
• TurboVNC is compatible with other VNC distributions, especially those that also support Tight encoding (such as TigerVNC, TightVNC, and UltraVNC).

New Features of the Program

When you download the latest version of TurboVNC, you can notice several improvements, such as:

• A regression issue in version 3.0.3 has been fixed, which in rare cases caused a complete display freeze when automatic desktop resizing was enabled, and the viewer attempted to resize its window in response to a remote desktop size change.
• A problem was fixed that caused the TurboVNC viewer to throw an IllegalComponentStateException if "Remote desktop size" was changed to "Auto" in the TurboVNC viewer options dialog while actively receiving framebuffer updates from a VNC server.
• An issue was fixed where the "Reset all options to defaults" button in the TurboVNC viewer options dialog did not consider the values specified in ‎~/.vnc/default.turbovnc.
• The TurboVNC viewer now works around an issue in recent versions of GNOME that caused irregular behavior with automatic desktop resizing.
• The default X startup script (xstartup.turbovnc) now searches both /usr/share/xsessions and /usr/share/wayland-sessions for a desktop session file matching the specified window manager. This resolves an issue where the classic GNOME window manager could not be used with the TurboVNC server on Fedora 40 and later versions.
• The default X startup script (xstartup.turbovnc) now attempts to launch MATE or Xfce (in that order) if no window manager is specified and no GNOME session desktop file is found. This fixes a regression in version 3.2 beta1[4] where the default X startup script no longer launched the default window manager on Ubuntu MATE or Xubuntu if no window manager was specified.
• The "Clear the list of saved connections" button in the "Global" tab of the TurboVNC viewer options dialog now clears only the connection history. A separate button has been added to clear saved options for each host individually.

Fixing the Complete Freeze Issue During Automatic Resizing

A bug was found in version 3.0.3 that caused the viewer to completely stop working ("complete freeze") in rare cases.

This issue occurred when the automatic desktop resizing option was enabled, and the viewer attempted to resize its window in response to a remote desktop size change. This bug has now been fixed.

Fixing IllegalComponentStateException When Changing Desktop Size to "Auto"

By downloading the latest version of TurboVNC, another issue was resolved that caused a technical error message ("IllegalComponentStateException") in the TurboVNC Viewer.

This problem occurred when the "Remote desktop size" setting was changed to "Auto" in the viewer options window while the program was receiving screen updates from the VNC server.

Fixing the "Reset All Options to Defaults" Button Not Working Completely

An issue was fixed where the "Reset all options to defaults" button in the viewer options window did not consider the values specified in the user's default settings file (~/.vnc/default.turbovnc). Now, pressing this button will reset all options to the default values, including those in the user's file.

Overcoming Irregular Resizing Issue in GNOME

A modification was made in the TurboVNC Viewer to overcome an issue present in recent versions of the GNOME desktop environment. This issue caused irregular and unexpected behavior when automatically resizing the desktop.

Improving Desktop Session File Search in X Startup Script

The default X startup script (xstartup.turbovnc) has been updated to search in two different folders (/usr/share/xsessions and /usr/share/wayland-sessions) for a file describing the desktop session to be launched (which is typically linked to the window manager). This fix resolves an issue that prevented the use of the classic GNOME window manager with the TurboVNC server on Fedora 40 and later versions.

Attempting to Launch MATE or Xfce as Default Window Manager

The X startup script (xstartup.turbovnc) has been modified to now attempt to launch the MATE or Xfce desktop environment (in that order) if no specific window manager is set in the settings, and no GNOME session file is found.

This fix restores functionality that was present in previous versions, where the script would launch the default window manager on systems like Ubuntu MATE or Xubuntu even if it wasn't explicitly specified.

Separating the functions of clearing connection history and host options: The "Clear the list of saved connections" button in the "Global" tab of the viewer options window now clears only the saved connection history, and a new separate button has been added to clear saved options for each host individually. This provides users with better control over the data they wish to clear.

Downloading the latest TurboVNC version focuses on fixing some issues found in previous versions of TurboVNC Viewer, improving compatibility with the GNOME desktop environment, and providing users with better control over the program settings.
