Additional + tuning parameters are added. TSLIB touchscreen calibration + is supported. Tested on Qtmoko Neo Freerunner. + + A tool, misc/uinput.pl, is provided to diagnose uinput + behavior on new devices. + + The env. vars. X11VNC_UINPUT_BUS and X11VNC_UINPUT_VERSION + are available if leaving them unset does not work. + + The Linux uinput non-X11 input injection can now be bypassed: + events can be directly written to the /dev/input/event + devices specified by the user (direct_abs=..., etc.) + + A -pipeinput input injection helper script, + misc/qt_tslib_inject.pl is provided as a tweakable + non-builtin direct input injection method. + + The list of new uinput parameters for the above two features is: + pressure, tslib_cal, touch_always, dragskip, btn_touch; + direct_rel, direct_abs, direct_btn, direct_key. + + The included SSL enabled Java VNC Viewers now handle Mouse + Wheel events. + + + miscellaneous new features and changes: + + In -reflect mode, the libvncclient connection can now have + the pixel format modified via the environment + variables X11VNC_REFLECT_bitsPerSample, + X11VNC_REFLECT_samplesPerPixel, and + X11VNC_REFLECT_bytesPerPixel + + In -create mode the following environment variables are added + to fine tune the behavior: FIND_DISPLAY_NO_LSOF: + do not use lsof(1) to try to determine the Linux VT, + FIND_DISPLAY_NO_VT_FIND: do not try to determine the + Linux VT at all, X11VNC_CREATE_LC_ALL_C_OK: do not bother + undoing the setting LC_ALL=C that the create_display + script sets. The performance of the -create script + has been improved for large installations (100's of + user sessions on one machine.) + + In -unixpw mode, one can now Tab from login: to Password. + + An environment variable, X11VNC_SB_FACTOR, allows one to scale + the -sb screenblank sleep time from the default 2 secs. + + In -rawfb mode, a bug is fixed in setting the number of bits + per pixel. + + Documented that -grabkbd is no longer working with some/most + window managers (it can prevent resizing and menu posting.) + + The macosx deprecated interface GetMainDevice() call is removed. + Compile with -DX11VNC_MACOSX_USE_GETMAINDEVICE if needed + for an old macosx version... + + Miscellaneous code cleanup. + +----------------------------------------------------------------------------- + + +x11vnc 0.9.12 2010-09-10 + +New in the 0.9.12 x11vnc release: + + One can now specify the maximum number of displays + that can be created in -create mode via the + env. var. X11VNC_CREATE_MAX_DISPLAYS + + The X11VNC_NO_LIMIT_SHM env. var. is added to skip any + automatic shared memory reduction. + + The kdm display manager is now detected when trying not to get + killed by the display manager. + + miscellaneous new features and changes: + + A compile error is fixed when using --with-system-libvncserver + pointing to LibVNCServer 0.9.7. + + -nevershared -forever usage mode is documented. + + Old SuSE broken thread local storage is documented. + + x11vnc exit cases are documented. + + A compile bug from forced use of Xdefs.h is worked around. + + +----------------------------------------------------------------------------- + + +x11vnc 0.9.11 2010-08-08 + +New in the 0.9.11 x11vnc release: + + The source tree is synchronized with the most recent libvncclient + (this only affects -reflect mode.) The build is fixed + for incompatibilities when using an external LibVNCServer + (e.g. ./configure --with-system-libvncserver...) + + The SSL enabled Java VNC Viewer Makefile has been modified so + that the jar files that are built are compatible back + to Java 1.4. + + In -reflect mode cursor position updates are now handled + correctly. + + In -create/-unixpw mode, the env. var. FD_USERPREFS may be set + to a filename in the user's home directory that includes + default username:options values (so the options do not + need to be typed every time at the login prompt.) + + miscellaneous new features and changes: + + An option -always_inject is provided: Even if there is no + displacement (dx = dy = 0) for a VNC mouse event force + the pointer to the indicated x,y position anyway. + + New java viewer debugging and workaround applet parameters: + debugKeyboard mapF5_to_atsign forbid_Ctrl_Alt + + You can set X11VNC_AVAHI_NAME, X11VNC_AVAHI_HOST, and/or + X11VNC_AVAHI_PORT environment variables to override the + default values. For example: -env X11VNC_AVAHI_NAME=wally + + When opening the X11 display extra XAUTHLOCALHOSTNAME settings + are attempted. + + +----------------------------------------------------------------------------- + + +x11vnc 0.9.10 2010-05-03 + +New in the 0.9.10 x11vnc release: + + IPv6 is now supported for all usage modes: forward and reverse + connections, SSL and unencrypted, etc. + + The included SSL enabled Java VNC viewer applet now supports + Chained SSL Certificates (x11vnc -ssl always has.) + The applet autodects x11vnc and set GET=1 for faster + connecting via HTTPS. + + A demo CGI script 'desktop.cgi' shows how to create an + SSL encrypted, multi-user x11vnc web login desktop + service. The user logs into a secure web site and gets + his/her own virtual desktop and his browser accesses it + with the SSL Java VNC Viewer applet. + + A serverCert Java Viewer applet parameter is provided. + Use an authenticated HTTPS browser connection to set + this parameter (the user could set it locally too.) + The onetimekey tool has -certonly option for this scheme. + + The Xdummy script (use Xorg 'dummy' driver instead of Xvfb) + no longer requires being run as root. + + + miscellaneous new features and changes: + + In the Java viewer applet, debugCerts and debugKeyboard parameters + are provided. The debugging output of the applet is more + readable. Some corner-case bugs (e.g. socket exceptions) + are now handled gracefully. Parameters forbid_Ctrl_Alt + and mapF5_to_atsign are added. + + The amount of time to wait for HTTPS applet downloads to finish + can be set in env. var. X11VNC_HTTPS_DOWNLOAD_WAIT_TIME. + + The -xkb mode is automatically enabled if there are more than + 4 keysyms per key. + + -coe is now an alias for -connect_or_exit. + + The -input_eagerly option enables this LibVNCServer feature + (it is like -allinput.) + + The "%" unix password verification tricks for the -unixpw + option are now documented. They also run a command + in UNIXPW_CMD. + + In -create (-svc, etc.) modes, a warning is printed out if Xvfb + cannot be found. Xvfb '+kb' option is checked for. + The -env CREATE_DISPLAY_OUTPUT=/tmp/mydebug.txt debugging + option is documented. Try to preserve user's PATH + if possible. + + In XDMCP connection mode, a test for GDM listening only + on IPv6 (::1) is performed. The interface can also be + specified via FD_XDMCP_IF. + + The example scripts connect_switch, ultravnc_repeater.pl, inet6to4 + have settings to let them run reliably for long times + as daemons. They also support IPv6. + + IPv6 notes: for some very esoteric cases (e.g. -chatwindow) + IPv4 localhost may be required for local IPC. A demo + transition tool 'inet6to4' is also included (can be + used for other apps.) x11vnc options related to IPv6: + -listen6, -6, -no6, -noipv4, -noipv6, and -connect, + -proxy. + + Use STUNNEL_LISTEN in -stunnel mode to have it listen on a + particular interface. Also STUNNEL_PROG. + + New remote control query options: pointer_x, pointer_y, + pointer_same, pointer_root, and pointer_mask. A demo + script using them misc/panner.pl is provided. + + Remote control change of -clip option will not create new + framebuffer if the size has not changed (for panner.pl) + + The X11VNC_DISABLE_SSL_CLIENT_MODE env. var. can be set to + disable SSL client role in reverse connections. This + means the VNC viewer side must be in SSL client role. + UltraVNC repeater operation can benefit from this. + + The SSL_INIT_TIMEOUT is increased to 1 hour if 'repeater' + is detected in a reverse connect string. + + The X property X11VNC_TRAP_XRANDR can be set on a desktop to + force x11vnc to use the -xrandr screen size change + trapping code. + + The -sslScripts option prints out the SSL certificate management + scripts. + + Suggest '-auth guess' and '-findauth' if X connection fails. + + The TightVNC sercurity type (TightVNC features enabler) now + works for RFB version 3.8. + + RECORD scroll detection is now working with the new gtk/gdk scroll + mechanism. Set X11VNC_SCROLL_MUST_EQUAL to disable. + + +For more information: + + http://www.karlrunge.com/x11vnc/ + http://www.karlrunge.com/x11vnc/x11vnc_opts.html + x11vnc -help | less + +----------------------------------------------------------------------------- + + +x11vnc 0.9.9 2009-12-21 + + + +New in the 0.9.9 x11vnc release: + + A new option -findauth runs the FINDDISPLAY script that applies + heuristics to try to determine the correct XAUTHORITY + file. The use of '-auth guess' will use the XAUTHORITY + that -findauth reveals. This can be handy in with + the lastest GDM where the ability to store cookies in + ~/.Xauthority has been removed. + + If x11vnc is running as root (e.g. inetd or XDM/GDM/KDM) + the FD_XDM=1 mode will be tried if the above -findauth + or '-auth guess' command fails; it will find the + correct XAUTHORITY for the given display (this works for + XDM/GDM/KDM if the login greeter panel is up or if someone + has already logged into an X session.) You can also + set -env FD_XDM=1 to force it to be done on the first try. + + The -unixpw_system_greeter option, when used in combined + unixpw and XDMCP FINDCREATEDISPLAY mode (e.g. -xdmsvc), + enables the user to press Escape to jump directly to the + XDM/GDM/KDM login greeter screen. This way the user + avoids entering his unix password twice at X session + creation time. For subseqent logins to the same session, + he uses the regular x11vnc unixpw "login:" prompt. Also, + the unixpw login panel now has a short help displayed + if the user presses 'F1' that lists the options. + + The -appshare option enables simple application sharing based on + the -id/-sid mechanism. Every new toplevel window that + the application creates induces a new viewer window via + a reverse connection. The -id/-sid and -connect options + are required. Run 'x11vnc -appshare -help' for more info. + + Heuristics are applied to try to determine if the X display + is currently in a Display Manager Greeter Login panel + (e.g. GDM.) If so, x11vnc's creation of any windows and + use of XFIXES are delayed. + + This is to try to avoid x11vnc being killed after the user + logs in if the GDM KillInitClients=true is in effect. + So one no longer needs to set KillInitClients=false in + gdm.conf. Note that in recent GDM the KillInitClients + option has been removed. + + Also delayed is the use of the XFIXES cursor fetching + functionality; this avoids an Xorg bug that causes Xorg + to crash right after the user logs in. + + x11vnc now tries to be more aggressive in keeping up with VNC + client's framebuffer update requests. Some broken VNC + clients continuously spray these requests at VNC servers + (regardless of whether they have received any updates + or not.) The -extra_fbur option allows one to fine tune + the setting. + + The "-display WAIT:cmd=...", -find, -create modes now work + correctly for the user-supplied login program scheme + "-unixpw_cmd ...", as long as the login program supports + running commands specified in the environment variable + "RFB_UNIXPW_CMD_RUN" as the logged-in user. The mode + "-unixpw_nis ..." has also been made more consistent. + The username option "tag=..." can be used to set FD_TAG. + + The -stunnel option (like -ssl but uses stunnel as an external + helper program) now works with the -ssl "SAVE" and "TMP" + special certificate names. The -sslverify and -sslCRL + options now work correctly in -stunnel mode. Single port + HTTPS connections are also supported for this mode. + + The remote control command -R can be used to instruct x11vnc + to resend its most recent copy of the Clipboard, + Primary, or Cutbuffer selections: "x11vnc -R + resend_clipboard", "x11vnc -R resend_primary", and + "x11vnc -R resend_cutbuffer". + + miscellaneous new features and changes: + + The fonts in the GUI (-gui) can now by set via environment + variables, e.g. -env X11VNC_FONT_BOLD='Helvetica -16 bold' + and -env X11VNC_FONT_FIXED='Courier -14'. + + The value of the -timeout option is now also used for the timing + out of reverse connections. The -timeout exit will + occur if no client has made it to normal operating state + (instead of merely trying to connect.) + + One can add extra URL parameters to the HTTPS (-ssl) urls + via X11VNC_EXTRA_HTTPS_PARAMS without needing to edit + index.vnc. E.g.: -env X11VNC_EXTRA_HTTPS_PARAMS='?GET=1' + + One can make the libvncserver HTTP (non-SSL) server listen on + localhost: -env X11VNC_HTTP_LISTEN_LOCALHOST=1 (this way + only the single-port VNC+HTTPS is exposed to the network.) + + Warnings are printed out at startup if $DISPLAY appears to + start with "localhost:" (SSH X11 forwarding) or + "hostname:" (remote X display; will fail w/o -noshm) + + The -solid option now uses the DBUS_SESSION_BUS_ADDRESS env. var + if available. The -solid option now works in xfce. + If available, the dbus_launch(1) will be used in + FINDCREATEDISPLAY for gnome sessions. + + The bcx_xattach remote control command was added to facilitate + xattach and x2x desktop cursor switching. Other new + remote control commands: grab_state, ping:mystring, + grablocal, resend_cutbuffer, resend_clipboard, + resend_primary, keycode, keysym, fakebuttonevent, + ptr, sleep, get_xprop, set_xprop, wininfo, pointer_pos, + mouse_xy, noop, guess_dbus, DIRECT:query. Remote control + scripting, -query_retries, and -remote_prefix were + also added. + + In -rawfb mode the X display will not be opened at all unless + the -rawfb string is prefixed with '+' or -display + was specified on the cmdline. + + For multiple, separate x11vnc instances on the same X display, + one can rename the X11VNC_REMOTE, X11VNC_TICKER, and + VNC_CONNECT property names to unique ones. + + The -showrfbauth option prints out the VNC rfbauth password. + + The XDAMAGE mechanism is now automatically disabled for a + period of time if a game or screensaver generates too + many XDAMAGE rectangles per second. This avoids the X11 + event queue from soaking up too much memory. + + x11vnc does not switch on server autorepeat if any keys are + pressed down to work around a recent Xorg server and/or + gnome bug where the key will never stop repeating. + + Thse list of current clients is kept more up-to-date in the + tkx11vnc gui. Bugs in the gui setpass mode have been + fixed. + + Threads stability is further improved. See under the -threads + option help info about -env X11VNC_THREADS_NEW_FB_SLEEP=ms + + There is an experimental workaround: "-env X11VNC_WATCH_DX_DY=1" + that tries to avoid problems with poorly constructed + menu themes that place the initial position of the mouse + cursor inside a menu item's active zone. + + The crypt(3) function is now declared inside the x11vnc code on + all platforms (not just Linux). To disable this, set + CPPFLAGS='-DDO_NOT_DECLARE_CRYPT' while configuring. + (crypt is declared to avoid problems with header files.) + + Error reasons are printed for -storepasswd failures. + + Two scripts are added to x11vnc/misc: connect_switch and + ultravnc_repeater.pl + +For more information: + + http://www.karlrunge.com/x11vnc/ + http://www.karlrunge.com/x11vnc/x11vnc_opts.html + x11vnc -help | less + + + +----------------------------------------------------------------------------- + + +x11vnc 0.9.8 2009-07-08 + + +New in the 0.9.8 x11vnc release: + + Better reliability for the Java Viewer applet when connecting + through a Web Proxy via HTTPS. A proxy hostname + and port can be specified via applet parameters. + Proxy Authentication via Auth-Basic is supported. + More x11vnc printout in -ssl is provided to help + troubleshoot this mode and other ssl connections. + + Stability improvements to -threads mode. Running x11vnc this + way is more reliable now. Threaded operation sometimes + gives better interactive response and faster updates. The + threaded mode now supports multiple VNC viewers using + the same VNC encoding (some only on Linux or enabled + at build time.) The threaded mode can also yield + a performance enhancement in the many client case + (e.g. class-room broadcast.) We have tested with 30 to + 50 simultaneous clients. See also -reflect. + + + miscellaneous new features and changes: + + x11vnc automatically tries to work around an Xorg server bug + involving infinitely repeating keys when turning off key + repeating. Use -repeat if the automatic workaround fails. + Also, the environment variable X11VNC_IDLE_TIMEOUT + (seconds) is provided. + + In -reflect mode the environment variable X11VNC_REFLECT_PASSWORD + is provided. + + The -clip mode works under -rawfb. + + The -nounixpw option can disable unixpw mode if an earlier option + enables it (e.g. -svc). + + Scroll detection is skipped for windows with 'OpenOffice' in + their name. + + +For more information: + + http://www.karlrunge.com/x11vnc/ + http://www.karlrunge.com/x11vnc/x11vnc_opts.html + x11vnc -help | less + +----------------------------------------------------------------------------- + + +x11vnc 0.9.7 2009-03-31 + + +New in the 0.9.7 x11vnc release: + + Basic support for building with VirtualGL's TurboVNC (an + enhanced TightVNC for fast LAN high framerate usage) + encoding and TightVNC modifications. More info: + http://www.karlrunge.com/x11vnc/faq.html#faq-turbovnc + and x11vnc/misc/turbovnc/README. + + The -ncache_cr option has been fixed and so in -ncache mode + smooth opaque window motions are now work correctly. Try + it out to see how smooth it is even on a slow link. + + Support for Linux text consoles (virtual terminals, e.g. 1-6) + is provided via, e.g., 'x11vnc -rawfb vt2' (for virtual + terminal #2). + + This is like LinuxVNC (i.e. text only), it avoids using + /dev/fb and uses /dev/vcsaN instead (the '-rawfb console' + mode uses /dev/fb.) With /dev/vcsaN the text terminal + is accessible even it if is not the currently active one. + + The -rawfb option now supports framebuffers with bits per pixel + less than 8 (e.g. 4 or 1 bpp.) + + Reverse connections now work in Anonymous Diffie Hellman SSL/TLS + mode. Reverse connections also work for VeNCrypt and + ANONTLS modes. + + + miscellaneous new features and changes: + + The included SSL enabled UltraVNC java viewer now has a + configurable [Home] entry in the drives drop down menu. + + In the -create, -svc, etc. modes one can now specify a + range of X displays to ignore in X11VNC_SKIP_DISPLAY. + Improvements and bugfixes were made to the find_display + and create_display scripts. FD_EXTRA option is provided. + + The '-rawfb video' option finds the video device file more + carefully. + + The -rmflag option allows a new way to indicate to other + applications that x11vnc has started. + + All of the java applet parameters are now documented in + the classes/ssl/README file. + + There is now a "sendbell" remote control command. + + A one-time -padgeom once:WxH mode is added. + + Improvements to the CUPS Terminal Services helper mode. + + If the X display cannot be opened normally then the env. var. + XAUTHLOCALHOSTNAME=localhost is tried. + + Bugfix for selection transfer to a now non-existent X window + (Thunderbird can cause this.) Related, the env. variable + LIBXCB_ALLOW_SLOPPY_LOCK is now set by default. + + Bugfix for -8to24 mode due to nonstandard indexed color support. + + The libvncserver and x11vnc autoconf/automake settings have + been improved. + + libXrandr include file is now found on Solaris. + + +For more information: + + http://www.karlrunge.com/x11vnc/ + http://www.karlrunge.com/x11vnc/x11vnc_opts.html + x11vnc -help | less + +----------------------------------------------------------------------------- + + +x11vnc 0.9.6 2008-12-10 + + +New in the 0.9.6 x11vnc release: + + x11vnc's SSL encryption is extended to support the VeNCrypt and + TLS (older; vino) SSL/TLS security type extensions to VNC. + + Anonymous Diffie-Hellman key exchange (-ssl ANON) and Certificate + Revocation List support (-sslCRL) is added to the SSL + encryption mode. + + The Java viewer applet can now be served up through the VNC port + (5900) in addition to the normal HTTP port (5800) via + the -http_oneport option. Previously this only worked + for SSL connections and HTTPS. + + The "-rfbport PROMPT" mode presents a simple gui for the user + to select a port for the x11vnc service and a few other + settings. This enables a menu entry for naive users + that is included in x11vnc.desktop. + + If x11vnc is not built with the Avahi Zeroconf library an external + helper program (avahi-publish or dns-sd on Mac OS X) + is used instead. + + miscellaneous new features and changes: + + The default mode for '-ssl' is now the '-ssl SAVE' mode; i.e. + the generated certificate is saved and reused in + subsequent sessions rather than being discarded. + Use '-ssl TMP' recover the old way. This change made + to for it to be more likely that the VNC Viewer can save + the accepted cert for future authentications. + + The solid background color option works on the Mac OS X console. + + The -reopen option enables x11vnc to try to re connect to the X + display if GDM (or other display manager) kills it just + after the user logs in. + + The -dhparams option can be used to point to your own Diffie + Hellman parameters. + + The -setdefer option allows tuning how quickly updates will + be sent.

Tuning is possible with -xd_area. + + DAMAGE is available on recent Xorg servers and Solaris 10. + + -wireframe: Heuristics are used to guess when a window is being + moved or resized and during this period show only a + moving wireframe outline. Just like on video cards in + the 90's, remember? This is to avoid window "lurching" + when you move or resize one opaquely. + + Also, -wirecopyrect applies the VNC CopyRect encoding + for the moved window. Both are on by default, use + -nowireframe or -nowirecopyrect to disable (aka -nowf + and -nowcr). + + -scrollcopyrect: Sniff the X11 protocol via the RECORD extension + and to try to detect window scrolls (e.g. via scrollbar, + Up/Down arrow, etc). When detected, the VNC CopyRect + encoding is applied to the scrolled regions for a speedup. + + The contents of the scrolling window may only be + approximate while it is being scrolled: e.g. tearing, + bunching-up, etc. The heuristics will also miss scrolls + by certain toolkits or applications, so those will still + happen the slow way. To disable use -noscrollcopyrect + (aka -noscr). Tuning is also available, see the -help + entry. + + -listen: Makes x11vnc listen only on a single network interface. + -localhost now implies '-listen localhost'. + + -rawfb: Instead of polling an X server framebuffer, poll a raw + one (i.e. a mapped file or a shm segment). E.g. for + the linux framebuffer device: + + -rawfb map:/dev/fb0@1024x768x32 + + This is a bit out of x11vnc's scope but may have some + interesting applications.
