More features are described here. Normally a virtual X session Xvfb is created for each user, but it also works with X sessions on physical hardware. I wrote x11vnc back in because x0rfbserver was basically impossible to build on Solaris and had poor performance. I also created enhancements to improve the interactive response, added many features, and etc. Do check the FAQ and this page first; I realize the pages are massive, but you can often use your browser's find-in-page search action using a keyword to find the answer to your problem or question.

Try inserting the string " faq. Background: VNC Virtual Network Computing is a very useful network graphics protocol applications running on one computer but displaying their windows on another in the spirit of X, however, unlike X, the viewing-end is very simple and maintains no state. It is a remote framebuffer RFB protocol.

For Unix, the traditional VNC implementation includes a "virtual" X11 server Xvnc usually launched via the vncserver command that is not associated with a physical display, but provides a "fake" one X11 clients xtermfirefoxetc. A remote user then connects to Xvnc via the VNC client vncviewer from anywhere on the network to view and interact with the whole virtual X11 desktop. The VNC protocol is in most cases better suited for remote connections with low bandwidth and high latency than is the X11 protocol because it involves far fewer "roundtrips" an exception is the cached pixmap data on the viewing-end provided by X.

Also, with no state maintained the viewing-end can crash, be rebooted, or relocated and the applications and desktop continue running. Not so with X Motif, GNOME, and similar applications that would yield very poor performance over a high latency link. Howeversometimes one wants to connect to a real X11 display i. Maybe you want to close down an application cleanly rather than using killor want to work a bit in an already running application, or would like to help a distant colleague solve a problem with their desktop, or would just like to work out on the deck for a while.

This is where x11vnc is useful. In this basic example let's assume the remote machine with the X display you wish to view is " far-away.

Step 0. Download x11vnc see below and have it available to run on far-away. Similarly, have a VNC viewer e. Step 1. By some means log in to far-away. You can use sshor even rlogintelnetor any other method to do this. We do this because the x11vnc process needs to be run on the same machine the X server process is running on otherwise things would be extremely slow. Step 2.It allows remote access from a remote client to a computer hosting an X Window session and the x11vnc software, continuously polling [4] the X server's frame buffer for changes.

Instead, it uses the existing X11 display shown on the monitor of a Unix-like computer in real time, unlike other Linux alternatives such as TightVNC Server. However, it is possible to use Xvnc or Xvfb to create a 'virtual' extra display, and have x11vnc connect to it, enabling X access to headless servers. It also has options for connection via a secure SSL link [4]. Reading pixel data from the physical frame buffer can be much slower than writing to it because graphics devices are not optimized for reading and so a sequential pixel by pixel check would often be too slow.

To improve the situation, x11vnc reads in full rows of pixels separated by 32 pixels vertically. Once it gets to the bottom of the screen it starts again near the top with a slightly different offset. After 32 passes like this it has covered the entire screen.

This method enables x11vnc to detect changes on the screen roughly 32 times more quickly than a sequential check would unless the changes are very small, say only 1 pixel tall. If the X11 DAMAGE extension is present, x11vnc uses it to provide hints where to focus its polling, thereby finding changes even more quickly and also lowering the system load. When x11vnc receives user input events keystrokes, pointer motion, and pointer button clicks from a VNC viewer, it must inject them synthetically into the X server.

For non-X11 managed devices such as the Mac OS X graphics display different programming interfaces must be used.

Often special-purpose systems are built using the X Window System to manage the graphical display. This enables remote monitoring, control, and troubleshooting of the special-purpose system. Sometimes this saves sending a technician to a remote site or allows users to control equipment from their workstation or laptop.

If x11vnc cannot be run on the special-purpose system, sometimes it can be run on a nearby computer and poll the X server frame buffer over the network. This is how proprietary X terminal devices can be accessed via x11vnc. Although x11vnc's primary use is for X servers associated with physical graphics hardware, it can also attach to virtual X servers whose frame buffers exist in RAM only such as Xvfb or a Sun Ray session.

The interactive response of x11vnc and Xvfb may not be as fast as Xvnchowever this mode enables features that Xvnc does not have, such as SSL encryption and Unix usernames and passwords. While this makes the client easier to implement, there is a price to pay in terms of interactive response. For example, every re-exposure of a window or background region needs to have its compressed pixel data resent over the network.

This effect is particularly noticeable for windows with complex or photo regions such as a web browser window that gets iconified and deiconified or re-exposed often. It is enabled via the -ncache option.

When creating the RFB frame buffer in this mode, x11vnc allocates a very large scratch region below the top portion used for the actual on-screen pixel data.

These moves are done locally on the viewer side. In this way x11vnc can manage the scratch region to store and retrieve pixel data without having to resend it over the network. There are some disadvantages, however.This is fine if you want to control your Raspberry Pi remotely and do not have a monitor connected to the Raspberry Pi; however, I want to connect the Raspberry Pi to a monitor and then control the Raspberry Pi desktop, displayed on the monitor, from a Mac across the room.

To the best of my knowledge, TightVNC does not provide this feature If I am mistaken, please leave a comment at the end of this post. TightVNC only allows a connection to a virtual screen.

The result is that you see a virtual desktop on the remote computer, not the desktop on the display connected to the Raspberry Pi. My solution uses the VNC server, x11vnc to correct this.

Herd behavior article answer key

The first step is to install the x11vnc server on the Raspberry Pi. We will use terminal commands to do this. Type a password and verify. The password does not have to be lengthy.

I use a six digit pin. Select y to write the password to the Raspberry Pi. In a nutshell, the command runs x11vnc in the background using the password created earlier and then sets the display to port Later I will demonstrate how to run this command using an easier to remember shell script.

You will need to add it manually in the All Computers area. XXX into the Server Address text area, as shown in the image below. Substitute XXX. In this example, the IP address is Enter the password, choose whether or not to remember the password in the keychain, and then select the Connect button.

After a second or two, the Mac will mirror the main display on your Raspberry Pi as shown in the image below:. If you look on the actual display connected to the Pi, you will notice the mouse moves in sync with your Mac mouse. The entire x11vnc command with parameters is hard to remember. Create a shell script to make it easier to start the x11vnc server.

The single line of code shown below will create a new shell script in the home directory:. Use the ls command to verify that a new script file named x11vnc. If you need to stop kill the x11vnc server, use the command below to determine the process ID for x11vnc. Where XXXX is the process number identified in the previous step.

The x11vnc server will stop. If you need to restart, just enter the short shell script name:. It took me some time, much research, and much trial and error to figure this out. I was never able to find complete instructions online that work or a step-by-step guide. My goal has been to write them in such a way that even those new to Linux can do this.

Combs, Ph. Install x11vnc The first step is to install the x11vnc server on the Raspberry Pi. It is good practice to first update the Raspian repositories using the command below: sudo apt-get update Install x11vnc using the command below: sudo apt-get install x11vnc Raspbian will display the following: Reading package lists Done Building dependency tree Reading state information Done The following extra packages will be installed: libvncclient0 libvncserver0 tcl tcl8.
