Ich starte den VNC-Client auf dem Remote-Computer mit dem Befehl „x11vnc -display :2“. Dann versuche ich, von meinem lokalen Computer aus mit dem Befehl „xvnc4viewer“ eine Verbindung herzustellen. Dann fragt er nach dem Servernamen und zeigt mir schließlich einen schwarzen Bildschirm.

#@ You can create an x11vnc password file by running: @#

#@ x11vnc -storepasswd password /path/to/passfile @#
#@ or x11vnc -storepasswd /path/to/passfile @#
#@ or x11vnc -storepasswd @#

#@ (the last one will use ~/.vnc/passwd) @#
#@ @#
#@ and then starting x11vnc via: @#
#@ @#
#@ x11vnc -rfbauth /path/to/passfile @#
#@ @#
#@ an existing ~/.vnc/passwd file from another VNC @#
#@ application will work fine too. @#
#@ @#
#@ You can also use the -passwdfile or -passwd options. @#
#@ (note -passwd is unsafe if local users are not trusted) @#
#@ @#
#@ Make sure any -rfbauth and -passwdfile password files @#

#@ @#
#@ Use x11vnc -usepw to automatically use your @#

14/10/2015 13:41:22 ------------------ USEFUL INFORMATION ------------------
14/10/2015 13:41:22 X DAMAGE available on display, using it for polling hints.
14/10/2015 13:41:22 To disable this behavior use: '-noxdamage'
14/10/2015 13:41:22
14/10/2015 13:41:22 Most compositing window managers like 'compiz' or 'beryl'
14/10/2015 13:41:22 cause X DAMAGE to fail, and so you may not see any screen
14/10/2015 13:41:22 updates via VNC. Either disable 'compiz' (recommended) or
14/10/2015 13:41:22 supply the x11vnc '-noxdamage' command line option.
14/10/2015 13:41:22 X COMPOSITE available on display, using it for window polling.
14/10/2015 13:41:22 To disable this behavior use: '-noxcomposite'
14/10/2015 13:41:22
14/10/2015 13:41:22 Wireframing: -wireframe mode is in effect for window moves.
14/10/2015 13:41:22 If this yields undesired behavior (poor response, painting
14/10/2015 13:41:22 errors, etc) it may be disabled:
14/10/2015 13:41:22 - use '-nowf' to disable wireframing completely.
14/10/2015 13:41:22 - use '-nowcr' to disable the Copy Rectangle after the
14/10/2015 13:41:22 moved window is released in the new position.
14/10/2015 13:41:22 Also see the -help entry for tuning parameters.
14/10/2015 13:41:22 You can press 3 Alt_L's (Left "Alt" key) in a row to
14/10/2015 13:41:22 repaint the screen, also see the -fixscreen option for
14/10/2015 13:41:22 periodic repaints.
14/10/2015 13:41:22
14/10/2015 13:41:22 XFIXES available on display, resetting cursor mode
14/10/2015 13:41:22 to: '-cursor most'.
14/10/2015 13:41:22 to disable this behavior use: '-cursor arrow'
14/10/2015 13:41:22 or '-noxfixes'.
14/10/2015 13:41:22 using XFIXES for cursor drawing.
14/10/2015 13:41:22 GrabServer control via XTEST.
14/10/2015 13:41:22
14/10/2015 13:41:22 Scroll Detection: -scrollcopyrect mode is in effect to
14/10/2015 13:41:22 use RECORD extension to try to detect scrolling windows
14/10/2015 13:41:22 (induced by either user keystroke or mouse input).
14/10/2015 13:41:22 If this yields undesired behavior (poor response, painting
14/10/2015 13:41:22 errors, etc) it may be disabled via: '-noscr'
14/10/2015 13:41:22 Also see the -help entry for tuning parameters.
14/10/2015 13:41:22 You can press 3 Alt_L's (Left "Alt" key) in a row to
14/10/2015 13:41:22 repaint the screen, also see the -fixscreen option for
14/10/2015 13:41:22 periodic repaints.

14/10/2015 13:41:22 XKEYBOARD: number of keysyms per keycode 7 is greater
14/10/2015 13:41:22 than 4 and 51 keysyms are mapped above 4.
14/10/2015 13:41:22 Automatically switching to -xkb mode.
14/10/2015 13:41:22 If this makes the key mapping worse you can
14/10/2015 13:41:22 disable it with the "-noxkb" option.
14/10/2015 13:41:22 Also, remember "-remap DEAD" for accenting characters.

******************************************************************************
Have you tried the x11vnc '-ncache' VNC client-side pixel caching feature yet?
The scheme stores pixel data offscreen on the VNC viewer side for faster
retrieval. It should work with any VNC viewer. Try it by running:
x11vnc -ncache 10 ...
One can also add -ncache_cr for smooth 'copyrect' window motion.
