If you Press start it will be shown as well and you will be asked to confirm running it. If you want to use a saved profile \"rc file\" you can do \"Misc -> rc\" and select the file and simply start x11vnc using the rc file. Alternatively, you could first use the \"Actions -> load-settings\" action to load in an \"rc file\" and then press \"Actions -> start\" to start up x11vnc based on those values. " set helptext(stop) " The \"Actions -> stop\" action sends a signal to the running x11vnc server indicating it should shutdown all connections and exit. The GUI stays running in case you want to start a new x11vnc or attach to another one. Use \"Actions -> Quit\" if you then want to have the gui exit.

This can be done even in the attached state. Intended for debugging the gui. The help item for \"Actions -> start\" gives the same info. If you want to load in a saved profile \"rc file\" use \"Misc -> rc\" and select the file. \"Actions -> load-settings\" does a similar thing with an rc-file, but reading the file and setting the gui variables to its values.

" set helptext(attach) " Attach to a running x11vnc server, if possible. Switches to connected state if successful. Usually the channel used to attach is via the X display (VNC_CONNECT rootwin property) being polled by the x11vnc server. To change or set the X display to use do \"Displays -> display\". Sometimes the \"-connect /path/to/filename\" is used as the communcation channel. The running x11vnc has to know that \"/path/to/filename\" is the communication channel (i.e. it is using the same -connect option).

" set helptext(save-settings) " Construct a ~/.x11vncrc file based on the current settings and offer to save it in a file (default ~/.x11vncrc). If saved in a file other than the default, you can access the profile by using the \"-rc \" option when starting x11vnc. If an rc file entry begins with \"#d\" that means the current setting is at the Default value and so you probably want to leave it commented out with the \"#\" character. If an rc file entry begins with \"#?\" that means we think you probably do not really want to force the value to this setting. In either case, feel free to uncomment the line and/or change any of the parameter values in the file.

" set helptext(client) " After selecting a VNC client from the \"Clients -> current\" menu, you will be presented with a dialog that shows the information about the VNC client. You can choose to disconnect the client by clicking on the \"Disconnect\" checkbox and pressing \"OK\". There will be a confirmation dialog to doublecheck. Alternatively, you can fine tune the VNC client's input permissions by selecting any of the Keystrokes, Mouse Motion, or Button Clicks checkboxes and pressing \"OK\". This is like the \"-input\" option but on a per-client basis. To not change any aspects of the VNC client press \"Cancel\". " set helptext(solid_color) " Set the -solid color value.

" set helptext(simple-gui) " Toggle between menu items corresponding the most basic ones and all possible settings. I.e. toggle between a simple gui and one for power users. " set helptext(Tray) " The tray/icon mode (started with \"x11vnc -gui tray ...\", etc.) presents a small icon that indicates the status of the running x11vnc server. Depending on your environment, this icon may be embedded in a system tray or applet dock, or simply be a standalone window. \"-gui tray\" will attempt to embed the icon in the system tray, while \"-gui icon\" is for a standalone window. Use \"-gui tray=setpass\" (or icon=setpass) to be prompted to set the session password at startup. When the icon has a light background, that means no VNC viewers are currently connected to the VNC display. When the icon has a dark background (i.e. reverse-video), that means at least one VNC viewer is connected to the VNC display. Moving the mouse pointer over the icon will popup a \"status balloon\" indicating the VNC display name and the names and info of any connected VNC viewers. Press the middle mouse button if the balloon does not appear. Clicking the left or right mouse button on the icon displays a menu of actions: Properties - Brings up the Properties dialog to set some basic parameters. The full tkx11vnc GUI may be accessed via the \"Advanced ...\" button. Press \"Help ...\" in the Properties dialog for more info. Help - Displays this help text. New Client - Presents an entry box where you type in the name of a computer that is running a VNC viewer in \"listen\" mode (e.g. vncviewer -listen). For a non-standard listening port use \"host:port\". Pressing \"OK\" will initiate the reverse connection. Use a blank hostname to skip it. Disconnect - Shows a popup menu of connected clients. Click on one to disconnect it, or click on \"All Clients\" disconnect all clients. Window View - Switch between the \"full\" gui (also known as \"Advanced\"), \"icon\" mode (small icon window with popups), or \"tray\" mode (small icon embedded in the system tray). This is a shortcut for the action: \"Properties -> Advanced -> Misc -> WindowView\". Stop x11vnc - Directs the x11vnc server to disconnect all vncviewers and then exit. The tray/icon GUI then exits as well. Termination: If the x11vnc server stops for any reason, the tray/icon gui will exit. If you delete the tray/icon (e.g. X out button), that is the same as the \"Stop x11vnc\" action in the menu. (This will disconnect any VNC viewer you are currently using to access the display since the x11vnc server is terminated). To terminate the tray/icon gui window but not the x11vnc server press Control-C on the tray/icon window. You can also do this (and much more) via Properties -> Advanced -> Actions -> Quit " set helptext(NewClient) " New Client - Presents an entry box where you type in the name of a computer that is running a VNC viewer in \"listen\" mode (e.g. vncviewer -listen). For a non-standard listening port use \"host:port\". Pressing \"OK\" will initiate the reverse connection. Use a blank hostname to skip it. " set helptext(Properties) " The Properties dialog allows you to set some basic parameters of a running x11vnc server. After modifying them press \"OK\" or \"Apply\" to apply the changes, or press \"Cancel\" to skip applying them. - \"Accept Connections\" toggles whether VNC viewers are allowed to connect or not. It corresponds to the \"-R unlock\" and \"-R lock\" remote-control commands. - \"Ask for Confirmation\" toggles whether a popup menu will be presented at the X display when a new VNC viewer attempts to connect. The person sitting at the X display can choose to accept or reject the connection or accept the connection in View-Only mode. It corresponds to the \"-R accept:popup\" and \"-R accept:\" remote-control commands. - \"All Clients ViewOnly\" toggles whether the entire VNC desktop is view only. All clients will only be able to watch when this is set (regardless of how they logged in). It corresponds to the \"-R viewonly\" and \"-R noviewonly\" remote-control commands. - \"Shared\" toggles whether multiple simultaneous connections are allowed or not. It corresponds to the \"-R shared\" and \"-R noshared\" remote-control commands. - \"Password\" lets you set the session password viewers may use to gain full access to the display. - \"ViewOnly Password\" lets you set the session password viewers may use to gain view only access to the display. NOTE: These \"session\" passwords only last for the current x11vnc session (they are not remembered, see the -storepasswd, -passwdfile, and -rfbauth x11vnc options for using stored passwords). If you set \"Password\" to the empty string that makes the \"View-Only Password\" empty as well and removes the need for any password to log in. If you set \"ViewOnly Password\" to the empty string that just removes the ViewOnly log in aspect: \"Password\" is still required to log in. - The \"Help ...\" button shows this help text. - The \"Advanced ...\" button replaces the Properties dialog with the full tkx11vnc GUI. All dynamic settings can be modified in the full GUI. -------------------------------------------------------------------- Don't Lock Yourself Out: If you are sitting at the physical X display you cannot get into too much trouble setting the Properties dialog values. However IF you are using a VNC Viewer to REMOTELY access the X display some items in the Properties dialog can lock you out of further access: \"Accept Connections\" if you disable this remotely, and accidentally disconnect your VNC viewer then you will not be able to reconnect. \"Ask for Confirmation\" if you enable this only someone sitting at the X display can confirm any new VNC connections. Furthermore, any current VNC viewers will be blocked while waiting for the confirmation (times out in 120 sec by default). \"All Clients ViewOnly\" if you enable this remotely, well you can no longer provide input to disable it. If you do lock yourself out you could log in remotely and start up a second x11vnc and connect to that one to try to fix things in the first one. Note that if there are two or more x11vnc's on the same display the use of the GUI may be ill-behaved. Terminate the second x11vnc as soon as you have fixed the setting in the first one. Use of a remote control command, e.g. \"x11vnc -R noviewonly\" or \"x11vnc -R unlock\" is a good way to avoid this problem. " set helptext(all) $helpall set helptext(Misc-Tuning:) " x11vnc has what seems like hundreds of tuning parameters! In this sub-menu we place some lesser used ones. Most likely you'll want to leave them at their default values, but you can try them out quickly with the gui to see if they improve things. " set helptext(Passwords:) " The items in this sub-menu pertain to setting passwords. Note that x11vnc has two types of password files: RealVNC-style ones (you can create them with x11vnc -storepasswd or other VNC utility program) you use these via -rfbauth; and plain-text file passwords you use via -passwdfile. Normally passwords cannot be changed by remote-control (e.g. the gui), but for the case of the \"Icon\" and \"Tray\" modes this constraint has been relaxed. In neither the RealVNC-style nor the plain-text file cases should the password files be readable by users you do not want to access the VNC server. Contrary to popular belief, the RealVNC-style passwords are not encrypted, merely obscured. x11vnc has the even less secure -passwd and -viewpasswd supplied on the command line. Be careful with these since they could be read by users with something like the ps(1) command. On some operating systems x11vnc tries to quickly overwrite them on the command line but it doesn't work everywhere. Regarding ViewOnly passwords (where a VNC client using that password can only watch the screen, not interact with it), this is not available with -rfbauth, but only with -passwdfile, -passwd, and -viewpasswd. " set helptext(Misc-Perms:) " In this sub-menu we provide some lesser used permission options. Regarding -alwaysshared, -nevershared, and -dontdisconnect, you probably should never use them and just use x11vnc's -shared and -forever options instead (these give basically the same functionality and if you mixed them too much unexpected things may happen). " set helptext(AlphaBlending:) " In this sub-menu we provide some tweak parameters for cursors (little icon at the mouse pointer) that have transparency (i.e. an Alpha channel in addition to Red, Green, and Blue RGB channels). For these cursors, some of the graphics underneath the cursor is allowed to be blended in: e.g. a drop-shadow (a terrible effect IMNSHO). AlphaBlending for x11vnc is only available when the XFIXES X extension is present (since otherwise it cannot see the cursors at all and so applies heuristics to show some fake cursors). AlphaBlending is only a problem with x11vnc when the cursors are not opaque. Opaque cursors (e.g. bitmap or simply colored cursor) are rendered correctly by x11vnc. Only when there is transparency does x11vnc have to make some approximation to transform the cursor to be opaque (the VNC protocol does not provide for an alpha channel in cursors, only RGB). The items in this sub-menu let you tweak x11vnc's approximation scheme for cursors with transparency. Hopefully you won't have to use them. Certain cursor \"themes\" may require adjustment however. " set helptext(OverlayVisuals:) " In this sub-menu are some options that involve fixing color problems for \"Overlay\" or \"Multi-Depth\" visuals. This problem is rare since overlay and multi-depth visual video hardware is rare. Some Sun, SGI, and HP machines are known to have them. The short answer is if you have a multi-depth visual display (e.g. 8 and 24 bits), and you see messed up colors in x11vnc try the \"-overlay\" option on Solaris or IRIX. A brief Background on pixels, color, and visuals: Pixels (picture elements) are kept in video memory as a certain number of bits-per-pixel (bpp). Most common are 8bpp, 16bpp, and 32bpp. Less common are 24bpp, 4bpp, and 1bpp (monochrome). How pixel values (i.e. values of the bits) are rendered into colors on the screen can be done via different \"Recipes\". These different recipes are referred to as \"visuals\". E.g. for 8bpp there is a PseudoColor visual that maintains a mapping (that can be changed dynamically) of the pixel values (256 possible ones) into RGB values. Other 8bpp visuals, e.g. StaticGrey and TrueColor have fixed, regular mappings and so provide less variation in kinds of colors. A visual's \"depth\" is how many of the pixels are used in the actual recipe. This may sound wasteful (i.e. not using some of the bits), but for 32bpp (4 billion colors) that is too much and nearly always only 24 for them are used. The most common Visual seems to be depth 24 TrueColor at 32bpp. This provides 16 million colors which is more than the number of pixels on most screens (1280x1024 = 1.3 million pixels). Another sometimes used visual that ignores some bits is depth 15 TrueColor at 16bpp. OK, now, finally, to the Overlay Visuals. Some hardware (or software emulations) allow different depth visuals to be used on the display at the same time. The pixels of windows using different depth visuals may overlap. The most common seems to be both 8 and 24 depth visuals on a 32bpp setup. 24 of the pixels can be used for one visual and the remaining 8 for the other. This is sometimes referred to as \"8+24\" mode. Furthermore, a speedup is achieved because writing graphics data to, say, the 8bit visual does not destroy the image data in the 24bit visual. Evidently popup menus can be done very quickly this way: they use the 8bit visual and when the popup goes away the graphics data in the 24bit visual is immediately reexposed without having the application redraw it. Also, some legacy applications can only use 8bpp visuals. But in these days of high color graphics and web browsers one would like the rest of the desktop to use depth 24 visuals. They often work on the multi depth visuals. How does this effect x11vnc? x11vnc nearly always polls the root window (container of all other windows). The root window will be one depth, e.g. 8 or 24. Any windows using the *other* depth will appear to have messed up colors (or just be black or some other solid color) when viewed via x11vnc. How to fix? Solaris and IRIX provide an API to extract the full snapshot of the display with all the colors correct. It comes to x11vnc as depth 24 TrueColor. To enable this use the \"-overlay\" option. Performance may be slower, but if the colors are correct that is a big improvement. " set helptext(8-Bit-Color:) " Some older displays (e.g. with limited Video RAM) use 8 bits-per-pixel color. This allows for only 256 different colors on the screen at the same time. This sometimes leads to problems with viewing these 8bpp displays via x11vnc. This sub-menu has some options that correspond to workarounds for this case. If you can configure the machine to use 16bpp it may be worth it to avoid the color problems (e.g. color flashing as the 8bit colormap is switched). " set helptext(SubWindow:) " This sub-menu has a couple options regarding having x11vnc poll a single window, not the entire display. This way just the window is shared. Note if the application pops up multiple windows they are not tracked and shared. So this is not application sharing. The application has to be very simple (e.g. a simple terminal or the image window on a webcam) for this mode to be usable. " set helptext(ResizeRotate:) " This sub-menu has some options regarding screens that support the X Resize, Reflection, and Rotation Extension (RANDR), and one expects screen resizing, reflection, or rotation to take place during the x11vnc session. This is pretty rare, but x11vnc seems to handle it reasonably well using this X extension. This mode is on by default in -id mode to try to track the changing size of the SubWindow. It is not on by default for full-screen mode because of the extra overhead, etc. " set helptext(WireFrame:) " This sub-menu has some options for the x11vnc wireframing speedup scheme. For x11vnc, Wireframing means to watch for toplevel windows being Opaquely Moved or Resized. When x11vnc detects this, it stops polling the screen and simply shows a \"wireframe\" outline of the window as it is being moved or resized. This avoids \"screen polling thrashing\" when the screen is changing so rapidly during this period. For various reasons this is usually much faster then letting the window manager do its own wireframing (you are encouraged to do Opaque moves and resizes when using x11vnc!) Also, once a moved window is released in its new position, x11vnc uses the VNC CopyRect encoding to very efficiently update the VNC viewers (each just copies the image data locally). This sort of scheme was used much in the 1990's on local displays because video hardware was slow at the time. x11vnc tries to use this same trick as a speedup for its activities (the network is much slower than video hardware writes, and the video hardware reads that x11vnc uses to poll the screen are still slow today). " set helptext(ScrollCopyRect:) " This sub-menu has some options for the x11vnc Scroll detection and CopyRect speedup scheme. For this mode, x11vnc \"spies\" on communication between the X server and applications using the RECORD extension. It looks for various patterns to detect a scrolled window. This only works for some applications, fortunately some important ones. Once the scroll is detected it uses the VNC CopyRect encoding for a big speedup. Screen polling is also sped up for this scheme. There are many tweakable parameters for this mode and they are described in the sub-menu items. " set helptext(XDAMAGE:) " The DAMAGE X extension allows the X server to send signals to x11vnc telling it which regions of the screen have been changed. This improves x11vnc's performance markedly. The DAMAGE extension must be available on the display for this to work. Unfortunately DAMAGE cannot be trusted completely for the changed regions, because often the reported changed region is much larger than the actual changed regions. Nevertheless, x11vnc uses the DAMAGE information very effectively as hints to improve its performance. The items in the sub-menu allow tweaking x11vnc's DAMAGE algorithm. " set helptext(SharedMemory:) " This sub-menu provides some options regarding SYSV shared memory usage (shm) by x11vnc. Usually you want shm turned on because the x11vnc process is nearly always running on the same machine the X server process is running on. SharedMemory gives a performance speedup. However, if you need to modify this scenario for special usage these options allow you to. " set helptext(Misc-Debug:) " This sub-menu contains a lot of debugging parameters usually used for debugging x11vnc itself. This is unlike the -debug_pointer and -debug_keyboard options that are useful in learning information, quirks, etc. about your local display and environment. " set helptext(Selection:) " This sub-menu contains some options centering around the Selection (also referred to as the Clipboard, Cutbuffers, etc). x11vnc will try to exchange the selections between the VNC viewers and the X server. You can adjust that behavior with these options. " set helptext(WindowView) " Set the Window View Mode for the gui. There are three modes: - full: Presents the full gui (Actions, Clients, etc, buttons, and the Text area and Set/Entry box). - icon: Presents a small icon instead of the full gui. Moving the mouse over it shows the VNC display name and any connected clients. Clicking on the icon pops up a menu of actions to perform. Among them is \"Properties\" that allows setting more parameters. Clicking on \"Advanced\" in \"Properties\" brings up the full gui. - tray: Attempt to embed the small icon in the system tray. If this fails it will resort to icon mode where the small icon is a standalone window. Note that in \"full\" mode if you delete the full gui window the gui terminates (but the x11vnc server keeps running). However under \"icon\" or \"tray\" mode if you bring up the full gui window via \"Properties -> Advanced\" and then delete it the gui does NOT terminate. Also note that by default in \"icon\" mode if you delete the icon window both the gui *and* the x11vnc server terminate. " set helptext(gui) " tkx11vnc is a simple frontend to x11vnc. Nothing fancy, it merely provides an interface to each of the many x11vnc command line options and remote control commands. See \"Help -> all\" for much info about x11vnc. For a simplier gui, run x11vnc in \"tray\" or \"icon\" mode such as \"-gui tray\", \"-gui icon\", or \"-gui tray=setpass\". In that mode the full gui is only available under \"Advanced ...\". Also, \"-gui ez\" will show fewer menu items (toggle via Misc -> simple_gui) All menu items have a (?) button one can click on to get more information about the option or command. There are two states tkx11vnc can be in: 1) Available to control a running x11vnc process. 2) Getting ready to start a x11vnc process. Most people will just use state 1). In state 1) the Menu items available in the menus are those that correspond to the x11vnc \"remote control\" commands. See the -remote entry under \"Help -> all\" for a complete list. Also available is the \"Actions -> stop\" item to shut down the running x11vnc server, thereby changing to state 2). There are other actions available too. In state 2) the Menu items available in the menus (\"Actions\", \"Clients\", etc.) are those that correspond to command line options used in starting an x11vnc process, and the \"Actions -> start\" item executes x11vnc thereby changing to state 1). To see what x11vnc startup command you have built so far, look at the (?) help for \"Actions -> start\" and it will show you what the command looks like. There is much overlap between the menu items available in state 1) and state 2), but it is worth keeping in mind it is not 100%. For example, you cannot set passwords or password files in state 1). (update: simple password setting is now allowed in \"tray\" or \"icon\" mode). Also note that there may be *two* separate X displays involved, not just one: 1) the X display x11vnc will be polling (and making available to VNC viewers), and 2) the X display this GUI is intended to display on. For example, one might use ssh to access the remote machine where the GUI would display on :11 and x11vnc would poll display :0. By default the gui will display on the value in the DISPLAY env. variable followed by the value from the -display option. To override this, use something like: \"-gui otherhost:0\", etc. GUI components: --- ---------- 1) At the top of the gui is a info text label where information will be posted, e.g. when traversing menu items text indicating how to get help on the item and its current value will be displayed. 2) Below the info label is the area where the menu buttons, \"Actions\", \"Clients\", etc., are presented. If a menu item has a checkbox, it corresponds to a boolean on/off variable. Otherwise it is either a string variable, or an action not associated with a variable (for the most part). 3) Below the menu button area is a label indicating the current x11vnc X display being polled and the corresponding VNC display name. Both will be \"(*none*)\" when there is no connection established. 4) Below the x11 and vnc displays label is a text area there scrolling information about actions being taken and commands being run is displayed. To scroll click in the area and use PageUp/PageDown or the arrow keys. 5) At the bottom is an entry area. When one selects a menu item that requires supplying a string value, the label will be set to the parameter name and one types in the new value. Then one presses the \"OK\" button or presses \"Enter\" to set the value. Or you can press \"Cancel\" or \"Escape\" to avoid changing the variable. Many variables are boolean toggles (for example, \"Permissions -> viewonly\") or Radio button selections. Selecting these menu items will NOT activate the entry area but rather toggle the variable immediately. CASCADES BUG: There is a bug not yet worked around for the cascade menus where the (?) help button gets in the way. To get the mouse over to the cascade menu click and release mouse to activate the cascade, then you can click on its items. Dragging with a mouse button held down will not work (sorry!). Key Bindings: In the Text Area: Control-/ selects all of the text. Anywhere: Control-d invokes \"Actions -> detach\" Anywhere: Control-a invokes \"Actions -> attach\" Anywhere: Control-p invokes \"Actions -> ping\" Anywhere: Control-u and Control-r invoke \"Actions -> update-all\" " set under_wally " Misc: Since x11vnc has so many settings and to avoid further confusion, the libvncserver options: -alwaysshared -nevershared -dontdisconnect are not available for changing in a running x11vnc (even though it is feasible). These options overlap with the x11vnc options -shared and -forever which are hopefully enough for most usage. They may be specified for x11vnc startup if desired. " global beginner_mode if {$beginner_mode} { set helptext(gui) " tkx11vnc is a simple frontend to x11vnc. It is currently running in \"ez\" or \"simple\" mode.
