|
|
|
|
*
|
|
|
|
*
|
|
|
|
* This program is based on the following programs:
|
|
|
|
*
|
|
|
|
* the originial x11vnc.c in libvncserver (Johannes E. Schindelin)
|
|
|
|
* x0rfbserver, the original native X vnc server (Jens Wagner)
|
|
|
|
* krfb, the KDE desktopsharing project (Tim Jansen)
|
|
|
|
*
|
|
|
|
* The primary goal of this program is to create a portable and simple
|
|
|
|
* command-line server utility that allows a VNC viewer to connect
|
|
|
|
* to an actual X display (as the above do). The only non-standard
|
|
|
|
* dependency of this program is the static library libvncserver.a.
|
|
|
|
* Although in some environments libjpeg.so or libz.so may not be
|
|
|
|
* readily available and needs to be installed, they may be found
|
|
|
|
* at ftp://ftp.uu.net/graphics/jpeg/ and http://www.gzip.org/zlib/,
|
|
|
|
* respectively. To increase portability it is written in plain C.
|
|
|
|
*
|
|
|
|
* Another goal is to improve performance and interactive response.
|
|
|
|
* The algorithm of x0rfbserver was used as a base. Many additional
|
|
|
|
* heuristics are also applied.
|
|
|
|
*
|
|
|
|
* Another goal is to add many features that enable and incourage creative
|
|
|
|
* usage and application of the tool. Apologies for the large number
|
|
|
|
* of options!
|
|
|
|
*
|
|
|
|
* To build:
|
|
|
|
*
|
|
|
|
* Obtain the libvncserver package (http://libvncserver.sourceforge.net).
|
|
|
|
* As of 12/2002 this version of x11vnc.c is contained in the libvncserver
|
|
|
|
* CVS tree and released in version 0.5.
|
|
|
|
*
|
|
|
|
* gcc should be used on all platforms. To build a threaded version put
|
|
|
|
* "-D_REENTRANT -DX11VNC_THREADED" in the environment variable CFLAGS
|
|
|
|
* or CPPFLAGS (e.g. before running the libvncserver configure). The
|
|
|
|
* threaded mode is a bit more responsive, but can be unstable (e.g.
|
|
|
|
* if more than one client the same tight or zrle encoding).
|
|
|
|
*
|
|
|
|
* Known shortcomings:
|
|
|
|
*
|
|
|
|
* The screen updates are good, but of course not perfect since the X
|
|
|
|
* display must be continuously polled and read for changes and this is
|
|
|
|
* slow for most hardware. This can be contrasted with receiving a change
|
|
|
|
* callback from the X server, if that were generally possible... (UPDATE:
|
|
|
|
* this is handled now with the X DAMAGE extension, but unfortunately
|
|
|
|
* that doesn't seem to address the slow read from the video h/w). So,
|
|
|
|
* e.g., opaque moves and similar window activity can be very painful;
|
|
|
|
* one has to modify one's behavior a bit.
|
|
|
|
*
|
|
|
|
* General audio at the remote display is lost unless one separately
|
|
|
|
* sets up some audio side-channel such as esd.
|
|
|
|
*
|
|
|
|
* It does not appear possible to query the X server for the current
|
|
|
|
* cursor shape. We can use XTest to compare cursor to current window's
|
|
|
|
* cursor, but we cannot extract what the cursor is... (UPDATE: we now
|
|
|
|
* use XFIXES extension for this. Also on Solaris and IRIX Overlay
|
|
|
|
* extensions exists that allow drawing the mouse into the framebuffer)
|
|
|
|
*
|
|
|
|
* The current *position* of the remote X mouse pointer is shown with
|
|
|
|
* the -cursor option. Further, if -cursorX or -X is used, a trick
|
|
|
|
* is done to at least show the root window cursor vs non-root cursor.
|
|
|
|
* (perhaps some heuristic can be done to further distinguish cases...,
|
|
|
|
* currently "-cursor some" is a first hack at this)
|
|
|
|
*
|
|
|
|
* Under XFIXES mode for showing the cursor shape, the cursor may be
|
|
|
|
* poorly approximated if it has transparency (alpha channel).
|
|
|
|
*
|
|
|
|
* Windows using visuals other than the default X visual may have
|
|
|
|
* their colors messed up. When using 8bpp indexed color, the colormap
|
|
|
|
* is attempted to be followed, but may become out of date. Use the
|
|
|
|
* -flashcmap option to have colormap flashing as the pointer moves
|
|
|
|
* windows with private colormaps (slow). Displays with mixed depth 8 and
|
|
|
|
* 24 visuals will incorrectly display windows using the non-default one.
|
|
|
|
* On Sun and Sgi hardware we can to work around this with -overlay.
|
|
|
|
*
|
|
|
|
* Feature -id <windowid> can be picky: it can crash for things like
|
|
|
|
* the window not sufficiently mapped into server memory, etc (UPDATE:
|
|
|
|
* we now use the -xrandr mechanisms to trap errors more robustly for
|
|
|
|
* this mode). SaveUnders menus, popups, etc will not be seen.
|
|
|
|
*
|
|
|
|
* Under some situations the keysym unmapping is not correct, especially
|
|
|
|
* if the two keyboards correspond to different languages. The -modtweak
|
|
|
|
* option is the default and corrects most problems. One can use the
|
|
|
|
* -xkb option to try to use the XKEYBOARD extension to clear up any
|
|
|
|
* remaining problems.
|
|
|
|
*
|
|
|
|
* Occasionally, a few tile updates can be missed leaving a patch of
|
|
|
|
* color that needs to be refreshed. This may only be when threaded,
|
|
|
|
* which is no longer the default.
|
|
|
|
*
|
|
|
|
* There seems to be a serious bug with simultaneous clients when
|
|
|
|
* threaded, currently the only workaround in this case is -nothreads
|
|
|
|
* (which is now the default).
