ultravnc error creating local image of screen

Create a Channel Bonding Interface Creating Local System Users · The VNC server creates a unique desktop for every display number. Sometimes, minimizing the remote desktop window to access your local computer would require you to log into the remote session, again, when you. Granting VNC access to control a screen provides nearly unrestricted access. Don't use the password of any local user on the client computer.

I can actually do anything now on the go, if I really have to. And the controls work well; never had an issue with the keyboard, the gestures like tap and hold to move objects work well, and the mouse tool works well. Not sure about some of the negative reviews, but this app has changed my life, my view of my phone, and the things I can get done. I am using an iPhone X by the way.

No issues. Thank you devs for this app. If you connect to a Mac OS VncViewer locks out when switching between desktops. The following data may be collected and linked to your identity:. The following data may be collected but it is not linked to your identity:.

Server for Windows: Fixed a missing system libraries error on Windows sometimes wtsapi Viewer for Windows: Now it is possible to change the port the Viewer listens on in the Listening mode and reconnect to the server right on the fly. Viewer for Windows: If minimized, a full-screen window is now restored as a full-screen application rather than a windowed one.

Viewer for Windows: Now correct resolution is reported in the Connection Info window when a remote screen size is not divided by 4. Viewer for Windows: Fixed grayscale color issue instead of a full color when a Tight decoder is used. Viewer for Windows: Fixed rare mouse scrolling issues.

Viewer for Windows: Now a file transfer dialog can be in the background. Source Code for Windows Server and Viewer : Fixed a thread-related deadlock when waiting for a thread to start. Source Code for Windows Server and Viewer : Fixed a bug with image corruption when multiple clients are connected to a server due to the refactored Server code. Source Code for Windows Server and Viewer : zlib library is updated to version 1.

Java Viewer: Fixed non-working key combinations with Ctrl. Java Viewer: Fixed memory leaking issues when reestablishing connection to the same server. Java Viewer: If the sever desktop is smaller than the Viewer window, gray is used to color the empty space. Server for Windows: New version of the built-in Java Viewer version 2. Server for Windows: Refactored the desktop architecture no changes in the functionality.

Viewer for Windows: A number of improvements in full screen mode. Viewer for Windows: Fixed a problem where the viewer could hang up or crash after disconnect. Viewer for Windows: Fixed minor errors in Tight decoder. Java Viewer: Added support for Local Mouse Cursor Shapes: dot cursor default , small dot cursor, system default cursor, no cursor.

Java Viewer: Viewport zoom property is now saved with connection history options. Java Viewer: Fixed hang-up on connecting to an out-of-range port number. Java Viewer: Fixed the width of the Host combobox control on the Connection dialog.

Java Viewer: Fixed a problem with the button panel when it did not render properly when starting the viewer in full screen mode for the first time. Installer for Windows: The passwords were not deleted from the registry if the options "do not use A crash dialog appeared on Windows shutdown when the server had connected clients. Server for Windows: Fixed the Apply button behavior in the Configuration window. It stayed disabled when "Use mirror driver" setting had been changed.

Server for Windows: Fixed mapping of additional TCP ports to specified screen area with negative coordinates. Server for Windows: Fixed -sharerect command-line option. It did not work properly with negative coordinates. Viewer for Windows: Now, the pointer position is sent to a remote server only if it has actually changed.

Viewer for Windows: The screen is now updated not at once but gradually, if the encoding is "Raw" and shared screen area is large. Viewer for Windows: Now, a list of files can be sorted by name, size and modification time in File Transfer system.

Viewer for Windows: Fixed occasional slow remote screen rendering. Viewer for Windows: Fixed connection option saving. Viewer for Windows: Fixed scroll bar in history combobox - it was always hidden. Viewer for Windows: Fixed Ctrl and Alt key handling. Sometimes the state of Ctrl and Alt buttons on the viewer toolbar did not correspond to the actual state of the hardware keys.

Viewer for Windows: Fixed unexpected behavior of the viewer. The viewer quit silently if the user entered incorrect VNC authentication password. Viewer for Windows: Fixed the button "Listening mode" accessibility after closing listening daemon. Java Viewer: Added maintenance of connection history and connection options. Java Viewer: Added autocomplete the connection form with the parameters of the most recent connection.

Java Viewer: Fixed a problem with erroneous message "Connection error: cannot write 16 bytes" appearing after pressing Close in the authentication dialog. Java Viewer: Fixed a bug with the viewer not showing remote screen when ShowControls option was set to 'no'. Installer for Windows: Added new MSI installer properties, to automate pre-setting passwords in silent mode. Server for Windows: Fixed a problem with querying local users on incoming connections.

TightVNC has a feature to let local user approve or reject incoming connections. If there was no user action within a pre-configured time limit, new connection will be either accepted or rejected automatically. Unfortunately, the timeout setting did not work correctly in previous version and that could result in infinite timeouts. That has been fixed. Server for Windows: Fixed the Apply button in the Configuration window - it stayed disabled on editing configuration settings.

This should resolve connectivity problems with Ubuntu systems and Vino servers. Viewer for Windows: Fixed hang-up on changing language or keyboard layout. To fix this problem, Windows message handling has been re-designed completely. Viewer for Windows: Fixed priority of preferred encodings. Previous version could work inefficiently with servers that do not support Tight encoding, because the Viewer could choose uncompressed Raw encoding instead of well-compressed ZRLE.

Viewer for Windows: Eliminated character limit on hostnames in the New Connection window. Viewer for Windows: Using correct line ending characters in cross-platform clipboard transfers. Viewer for Windows: Introduced a number of improvements and fixes in the user interface. That includes new commands in the toolbar and in the system menu, and architectural changes such as restoring the option to start new connections from the same Viewer instance.

Viewer for Windows: Adjusting viewer window size on remote desktop resizing. Viewer for Windows: Other minor improvements and fixes. The changes will not be visible to end user, but developers will appreciate new logging system. There should be no more static methods and global log objects, so it will be easier to reuse separate components in third-party applications.

Now all components work via a simple logging interface or can work without logging at all. Source Code Server and Viewer for Windows : Corrected build problems in various combinations of build configurations and platforms, in both Visual Studio and Visual Studio In the previous version, bit viewer was included by mistake. Installer for Windows: A few text labels and warning messages have been corrected. Server for Windows: Fixed a bug with uninitialized memory which could lead to random crashes.

Viewer for Windows: "Entering full screen" warning now includes an option for not showing it next time. Viewer for Windows: Fixed a problem with -optionsfile command-line option not working correctly unless full path was provided with the options file.

Also, error reporting have been improved when using -optionsfile. Viewer for Windows: Initial image of the remote desktop did not always render correctly in full screen. Now that should be fixed. Installer for Windows: Both bit x86 and bit x64 versions of the installer are available. Server for Windows: Full support for bit systems. Besides obvious benefits of using native architecture, this allows to attach so called "message hooks" to bit applications.

In a simple language, message hooks help at detecting screen activity, so that we can get updates almost immediately instead of polling the complete screen once per second or so. This makes screen reading ultra-fast in all supported versions of Windows, from Windows to Windows 7. Server for Windows: Improved performance when sharing a desktop with Windows Aero enabled.

With Aero, each screen reading operation is expensive, and we can improve performance by reading more pixels in less operations. Server for Windows: Improved logging. Most importantly, new version reports all incoming connections to Windows Event Log. Also, logging to text files has been improved - the service writes to the same log file from all its child processes. There's always just one log file, so it's easier to locate an error message or e-mail the log to technical support service.

Server for Windows: New option to configure extra ports mapped to arbitrary screen areas. If a client connects to such an extra port, it will be shown the corresponding part of the screen only. Server for Windows: New command-line options to share full desktop, primary monitor, selected monitor, a window, or an arbitrary rectangular area. Server for Windows: Optimized video processing for specific window classes. You can tell TightVNC to treat certain windows as video by providing a list of window class names.

Once a matching window is detected, its contents will be sent to clients continuously, with minimum delays. Viewer for Windows: Native bit version for improved performance in x64 systems. Viewer for Windows: Fast screen drawing and optimized decoders. Viewer for Windows: Desktop scaling that can be easily controlled via the toolbar. Viewer for Windows: New feature to pause screen updates.

You can freeze the remote desktop at any moment, e. Viewer for Windows: Unicode-enabled compilation. Unlike previous versions of TightVNC Viewer, this one fully supports Unicode and has no problems with using multiple national languages in user input, screen labels, file names etc. Viewer for Windows: Easily reusable source code. The viewer has been redesigned from the scratch. The primary design goal was to develop a "remote control SDK" and build the viewer on top of it.

And we've done just that. So not only we provide new version of the viewer, but we also give software developers an easy way to add remote control functionality to their products both free and commercial. The resulting SDK has a simple interface which hides all the complexity of the underlying protocols. Java Viewer: Desktop scaling that can be easily controlled via the toolbar. You can restrict the number of colors to save traffic, or prefer a rich-color format to maximize image quality.

From the GUI, you can choose a color mode with 8, 64, , , colors, or select the server's native number of colors. However, the core component supports any color format as allowed by the RFB protocol except palette-based modes.

Java Viewer: Corrected negotiation of the protocol version. New version should be able to connect to Mac OS X. Java Viewer: Various minor fixes and improvements. This problem affected Windows systems only. Server for Windows: CPU use was significantly reduced in idle periods when there are no users connected. Server for Windows: Fixed a problem which resulted in wrong color rendering in "big-endian" viewers e. PowerPC-based Mac viewers.

Server for Windows: Fixed rendering of semi-transparent mouse cursors. Previously, big black boxes could be seen instead of such cursors. Server for Windows: Introducing new "error handler" which allows saving memory dumps on critical errors. Server for Windows: In systems with swapped left and right mouse buttons, remote mouse events will be adjusted accordingly. As a result, the remote mouse should work just like the local one. Server for Windows: Fixed a number of problems led to errors on setting service passwords from the installer.

Server for Windows: Not allowing to enter administrative passwords longer than eight characters. Previous versions used only the first eight characters anyway but it was possible to enter longer passwords and that could confuse users who did not know about the limitation. Server for Windows: Fixed a problem with injecting lowercase characters when CapsLock was on on the server. Previous version generated uppercase characters when CapsLock was on, regardless of the Shift state.

It looks like there is a bug in Windows so we could do nothing better than to cook a workaround specifically for this case. Server for Windows: Fixed clipboard handling with multiple client connections. Previously, clipboard contents might not be sent to particular clients in certain circumstances. Server for Windows: Adjusted log verbosity levels for log messages generated by the control interface connection, so that such messages will not overload the log any more.

Server for Windows: Made minor adjustments in the user interface. Specifically, the "About Viewer for Windows: Fixed a number of problems with saving and restoring connection options. Viewer for Windows: Fixed user interface logic in the Options window.

There were incorrect dependencies between compression-related controls. Viewer for Windows: Improved phrasing for a number of error messages and log records in the file transfer module. Source Code: Visual Studio is now supported, upgraded solution and project files are included in the source distribution. Versions for Visual Studio are included as well. New version should be fully compatible with Windows desktop scaling.

This fix was developed for TightVNC 2. Server and Viewer for Windows: More fixes have been made to solve problems with clipboard transfers. Both server and viewer could send question characters instead of non-ASCII symbols if current input language did not match the text encoding.

These fixes complement related changes introduced in version 2. After creating five backup copies, it failed to rename old files and just overwrote the most recent log file. Viewer for Windows: Server-to-client clipboard transfers have been fixed.

Multiple files and directories can be copied at once, directories are processed recursively. Data compression is used to speed-up copying. Files can be renamed or removed, new directories can be created. File sizes are not limited by 4 Gb any more. Server for Windows: Implemented new architecture which separates service code from the user interface. This enables service-mode operation under Windows Vista and Windows 7.

Also, this fixes all known problems with multi-user features of modern Windows systems like Fast User Switching and Terminal Services. Server for Windows: Screen updates have become reliable. If something went wrong and the picture in the viewer is garbled, incomplete or outdated, it will be recovered in reasonable time.

There should be no more hidden menus or destructive window movements. If fast update detection methods fail, full-screen polling will keep updates going. Server for Windows: Featuring new secure administrative interface. Control interface can be optionally protected with a password to make sure users cannot reconfigure or shut down the service unless they know the password or have administrator privileges.

Server for Windows: There should be no more confusion between "default settings" and "user settings". In TightVNC 2. The "Configure Server for Windows: Featuring IP-based access control for incoming connections. You can even test the rules on specific IP addresses, prior to applying new rules. Installer: TightVNC 2.

It's smarter and more efficient. It tries to prevent reboots whenever possible. It invites to set passwords so that TightVNC Server would be ready to work right at the moment of finishing the installation. Finally, the complete self-installing TightVNC package both server and viewer parts, and the uninstall tool is only kilobytes in size. Server and Viewer for Windows: Keyboard handling has been improved. Older versions of TightVNC had problems with passing characters that do not fit in the Latin-1 code space.

This list of changes is not full. TightVNC Server 2. It does not include old TightVNC 1. So the right answer to the "What's New? TightVNC 1. Disabling file transfers if current user is unknown or nobody is logged in. Windows Server: Fixed rendering problems when multiple CopyRects were combined with normal updates. That could caused distortions that never updated even with full-screen polling active. Windows Server: Added new "-silent" command-line option which modifies the behavior of -install, -reinstall and -remove options and makes them not show informational windows on successful execution.

Note that -silent should precede other respective options in the command line. A specially modified VNC server could currupt the heap of the connected viewer causing its crash or malfunction. Now we save unsuccessful connections too so that users would not ever have to re-type server names after connection failures.

Also, several other enhancements were made to the code which handles the list of recent connections. Windows Viewer: Fixed a bug with not loading passwords from saved. Windows Viewer: Fixed problems under Windows Vista where Windows taskbar could remain visible above the full-screen window.

Windows Viewer: Fixed a bug with not saving log file name correctly on using the Browse button. Windows Viewer: Usability improvements in the "New Connection" dialog. Windows Packaging: Improved installer and uninstall utility.

In this version, self-installing executable will not try to install service in Windows Vista. Improved uninstall program always removes the WinVNC service if it was previously installed. Java viewer: Fixed a bug with ignoreCursorUpdates option in bit color mode caused the viewer to disconnect. Thanks to Damien Mascre for pointing out the issue. Java viewer: PORT parameter is not required any more, now it defaults to Java viewer: Do not defer update requests by default, to minimize delays in screen updates.

Java viewer: Improvements in reporting statistics on disconnect. Other minor improvements and bugfixes. All platforms: Made "host:port" parsing maximally compatible with VNC4. Interpreting a number in host names like somehost as an actual port number if it's not in the range [ Windows Server: Various user interface enhancements - changes in GUI labels, tray icon with a red border when incoming connections are not possible for any reason, more information in the tray icon tip, smarter logic in displaying the Properties dialog, and more.

Windows Server: Slightly improved handling of passwords. One of the notable changes is that now it's enough to enter a view-only password without providing primary password. The changes were ported from VNC 4. There are reports that this solves the problem with greyed username and password fields on Windows Server bug Windows Server: Bugfix for the bug attempt to restart the machine remotely via TightVNC led to disconnect if there was some non-saved data, and further connections were rejected.

Windows Viewer: Multiple selection now works in file transfers, thanks to developers at Novell and personally Rohit Kumar. Windows Viewer: The viewer terminated silently when the server dropped connection right after accepting it. Now we report such errors. Also, all required libraries are now included within the source distribution. Java viewer: Implemented scaling, either with a fixed scaling factor or automatic. From the other side, the viewer remains compatible with Java 1.

Scaling can be enabled with new "Scaling Factor" parameter but cannot be controlled from the GUI yet. Java viewer: Disabled focus traversal keys under JVMs 1. This fixes the problem with not sending Tab key events to the VNC server. Java viewer: Fixed wrong pixel format interpretation at decoding RichCursor pseudo-encoding local cursor could be rendered in wrong colors.

Other improvements and bugfixes, see ChangeLog files within the distribution for more details. Win32 server: Improved layout and functionality of the Properties dialog. Win32 server: More accurate password handling - now the server code tries to distinguish between "empty" and "unset" passwords better. Win32 server: New -shareall, -shareprimary and -sharearea command-line options, working similarly to the -sharewindow option.

Win32 server: Fixed problems with restoring desktop wallpaper. Win32 viewer: Fixed bug with not setting proper size of the viewer window. Unix server: Port numbers are now calculated modulo with vncviewer's -listen option. That makes it possible to listen on TCP ports under Java viewer: Automatic encoding selection based on measuring current network throughput.

Win32 server: Removed the code for "desktop optimizations" that was rather harmful than useful. Hopefully, this should fix problems with crashing Delphi applications. Also this should prevent settings like font smoothing always set to true on disconnect. Win32 server: Fixed the issue with port number edit boxes that were labeled incorrectly in the Properties dialog.

Win32 server: Disallowing clipboard transfers in view-only mode. Win32 server: Fixed the problem with wallpaper being removed only after completing the initial screen transmission. Win32 server: Minor improvements in the File Transfers dialog.

Win32 server: More context help messages in Properties and File Transfers dialogs. Unix server: Fixed a serious bug with sending cursor updates when there was no FrameBufferUpdateRequest from that client. Unix server: Fixed problems with building Xvnc on modern linux distributions, such as Fedora Core 3. Unix server: Disallowing clipboard transfers for view-only clients. Also, current mirror driver status is shown in the Hooks tab.

Win32 server: The option "Don't use mirror display driver even if available" is now functional. Win32 server: New option "Blank screen on client connections". When set and new client connects, the server's monitor is forced to go to power saving mode. Win32 server: Fixed bugs with saving certain settings in the registry, and bugs with setting default values when the registry is not writable.

Win32 server: Fixed a problem with one-pixel mouse offset. Win32 server: Fixed problems with inter-thread locking, this should solve "Unhandled message type received" problems. Win32 server: Fixed a problem with the setting "Block remote input on local activity", it was not working with DLL hooks disabled. Win32 server: Fixed various problems with file transfer implementation.

Win32 viewer: New "Auto" scaling mode. In this mode, the viewer scales remote desktop to fit local window or screen size. If the window size is changed, the scaling factor is adjusted automatically. Win32 viewer: Now the viewer checks server's capabilities and does not ever use non-standard protocol messages not supported by the server. This change affects file transfers only, as other features do not use non-standard protocol messages.. Java viewer: New "scale remote cursor" option has been added.

It allows to reduce or enlarge cursor image in the full-control mode. Java viewer: A cursor repaint problem has been fixed. Using the mirror driver greatly increases the speed and reliability of updates, and also desreases CPU utilization on the server. Win32 server: New polling algorithm has been implemented. It's similar to that found in x0rfbserver. New algorithm uses minimum CPU time when there are no changes on the screen, and detects major changes very quickly, resulting in greatly improved responsiveness on the client side.

Win32 server: Improved methods for filtering screen changes that actually do not change anything. New algorithm not only works faster, but it also detects changes much more accurately, leaving less work to encoders.

Note: Grey colors only work with 32 bits color screen resolution. This can range from 0 minimal to 10 maximum logging. Encodings are described here. Level 1 uses minimum of CPU time and achieves weak compression ratios, while level 9 offers best compression but is slow in terms of CPU time consumption on the server side. Use high levels with very slow network connections, and low levels when working over high-speed LANs. It's not recommended to use compression level 0, reasonable choices start from the level 1.

Quality level 0 denotes bad image quality but very impressive compression ratios, while level 9 offers very good image quality at lower compression ratios. Makes Windows Vista, Windows 7 faster. Make sure this directory is writable by system no mapped folder.

Any positive integer is valid. Zero indicates that no debugging information should be produced and is the default. A value of around will cause full debugging output to be produced. Log data may be output to a file or a console window or the MSVC debugger if the program was compiled with debugging active.

For testing purposes, or, potentially, when using multiple instances of WinVNC on Windows Terminal Server, this behaviour is undesirable. In some cases, it is preferable to only for connections originating from the local machine and aimed at the "localhost" adapter - a particular example is the use of VNC over SSH to provide secure VNC.

Without the tray icon you can't make realtime changes. You need to edit the ultravnc. Settings take efect after winvnc restart. This behaviour is undesirable when the server machine is being used as a shared workstation by several users or when remoting a single display to multiple clients for viewing, as in a classroom situation. This restriction was placed to ensure that misconfigured servers would not open security loopholes without the user realising.

If a server is only to be used on a secure LAN, however, it may be desirable to forego such checking and allow machines to have a null password.
