| 35 | /* |
| 36 | * This program is based on some ideas from the following programs: |
| 37 | * |
| 38 | * the initial x11vnc.c in libvncserver (Johannes E. Schindelin) |
| 39 | * x0rfbserver, the original native X vnc server (Jens Wagner) |
| 40 | * krfb, the KDE desktopsharing project (Tim Jansen) |
| 41 | * |
| 42 | * Please see http://www.karlrunge.com/x11vnc for the most up-to-date |
| 43 | * information about x11vnc. Some of the following text may be out |
| 44 | * of date. |
| 45 | * |
| 46 | * The primary goal of this program is to create a portable and simple |
| 47 | * command-line server utility that allows a VNC viewer to connect |
| 48 | * to an actual X display (as the above do). The only non-standard |
| 49 | * dependency of this program is the static library libvncserver.a. |
| 50 | * Although in some environments libjpeg.so or libz.so may not be |
| 51 | * readily available and needs to be installed, they may be found |
| 52 | * at ftp://ftp.uu.net/graphics/jpeg/ and http://www.gzip.org/zlib/, |
| 53 | * respectively. To increase portability it is written in plain C. |
| 54 | * |
| 55 | * Another goal is to improve performance and interactive response. |
| 56 | * The algorithm of x0rfbserver was used as a base. Many additional |
| 57 | * heuristics are also applied. |
| 58 | * |
| 59 | * Another goal is to add many features that enable and incourage creative |
| 60 | * usage and application of the tool. Apologies for the large number |
| 61 | * of options! |
| 62 | * |
| 63 | * To build: |
| 64 | * |
| 65 | * Obtain the libvncserver package (http://libvncserver.sourceforge.net). |
| 66 | * As of 12/2002 this version of x11vnc.c is contained in the libvncserver |
| 67 | * CVS tree and released in version 0.5. |
| 68 | * |
| 69 | * gcc should be used on all platforms. To build a threaded version put |
| 70 | * "-D_REENTRANT -DX11VNC_THREADED" in the environment variable CFLAGS |
| 71 | * or CPPFLAGS (e.g. before running the libvncserver configure). The |
| 72 | * threaded mode is a bit more responsive, but can be unstable (e.g. |
| 73 | * if more than one client the same tight or zrle encoding). |
| 74 | * |
| 75 | * Known shortcomings: |
| 76 | * |
| 77 | * The screen updates are good, but of course not perfect since the X |
| 78 | * display must be continuously polled and read for changes and this is |
| 79 | * slow for most hardware. This can be contrasted with receiving a change |
| 80 | * callback from the X server, if that were generally possible... (UPDATE: |
| 81 | * this is handled now with the X DAMAGE extension, but unfortunately |
| 82 | * that doesn't seem to address the slow read from the video h/w). So, |
| 83 | * e.g., opaque moves and similar window activity can be very painful; |
| 84 | * one has to modify one's behavior a bit. |
| 85 | * |
| 86 | * General audio at the remote display is lost unless one separately |
| 87 | * sets up some audio side-channel such as esd. |
| 88 | * |
| 89 | * It does not appear possible to query the X server for the current |
| 90 | * cursor shape. We can use XTest to compare cursor to current window's |
| 91 | * cursor, but we cannot extract what the cursor is... (UPDATE: we now |
| 92 | * use XFIXES extension for this. Also on Solaris and IRIX Overlay |
| 93 | * extensions exists that allow drawing the mouse into the framebuffer) |
| 94 | * |
| 95 | * The current *position* of the remote X mouse pointer is shown with |
| 96 | * the -cursor option. Further, if -cursor X is used, a trick |
| 97 | * is done to at least show the root window cursor vs non-root cursor. |
| 98 | * (perhaps some heuristic can be done to further distinguish cases..., |
| 99 | * currently "-cursor some" is a first hack at this) |
| 100 | * |
| 101 | * Under XFIXES mode for showing the cursor shape, the cursor may be |
| 102 | * poorly approximated if it has transparency (alpha channel). |
| 103 | * |
| 104 | * Windows using visuals other than the default X visual may have |
| 105 | * their colors messed up. When using 8bpp indexed color, the colormap |
| 106 | * is attempted to be followed, but may become out of date. Use the |
| 107 | * -flashcmap option to have colormap flashing as the pointer moves |
| 108 | * windows with private colormaps (slow). Displays with mixed depth 8 and |
| 109 | * 24 visuals will incorrectly display windows using the non-default one. |
| 110 | * On Sun and Sgi hardware we can to work around this with -overlay. |
| 111 | * |
| 112 | * Feature -id <windowid> can be picky: it can crash for things like |
| 113 | * the window not sufficiently mapped into server memory, etc (UPDATE: |
| 114 | * we now use the -xrandr mechanisms to trap errors more robustly for |
| 115 | * this mode). SaveUnders menus, popups, etc will not be seen. |
| 116 | * |
| 117 | * Under some situations the keysym unmapping is not correct, especially |
| 118 | * if the two keyboards correspond to different languages. The -modtweak |
| 119 | * option is the default and corrects most problems. One can use the |
| 120 | * -xkb option to try to use the XKEYBOARD extension to clear up any |
| 121 | * remaining problems. |
| 122 | * |
| 123 | * Occasionally, a few tile updates can be missed leaving a patch of |
| 124 | * color that needs to be refreshed. This may only be when threaded, |
| 125 | * which is no longer the default. |
| 126 | * |
| 127 | * There seems to be a serious bug with simultaneous clients when |
| 128 | * threaded, currently the only workaround in this case is -nothreads |
| 129 | * (which is now the default). |
