一、尝试解决的办法
①更新x11vnc至最新版本
root@kali:~# apt-get install x11vnc
②为x11vnc设置密码
root@kali:~# x11vnc -storepasswd
Enter VNC password:
Verify password:
Write password to /root/.vnc/passwd? [y]/n y
Password written to: /root/.vnc/passwd
③设置客户端vnc属性
在properties--experts--选项中：
设置ColorLevel:Full ,设置KeepAliveResponseTimeout:0
二、修改配置文件
root@kali:/etc/sysctl.d# vi /root/.vnc/xstartup #添加最后一行
xrdb $HOME/.Xresources
xsetroot -solid grey
#x-terminal-emulator -geometry 80x24+10+10 -ls -title "$VNCDESKTOP Desktop" &
#x-window-manager &
# Fix to make GNOME work
export XKL_XMODMAP_DISABLE=1
/etc/X11/Xsession
gnome-session & #使用gnome界面
三、重启服务
root@kali:~# systemctl restart x11vnc.service
root@kali:~# systemctl status x11vnc.service
● x11vnc.service - Start x11vnc at startup

27/06/2021 11:20:56 ------------------ USEFUL INFORMATION ------------------
27/06/2021 11:20:56 X DAMAGE available on display, using it for polling hints.
27/06/2021 11:20:56 To disable this behavior use: '-noxdamage'
27/06/2021 11:20:56
27/06/2021 11:20:56 Most compositing window managers like 'compiz' or 'beryl'
27/06/2021 11:20:56 cause X DAMAGE to fail, and so you may not see any screen
27/06/2021 11:20:56 updates via VNC. Either disable 'compiz' (recommended) or
27/06/2021 11:20:56 supply the x11vnc '-noxdamage' command line option.
27/06/2021 11:20:56
27/06/2021 11:20:56 Wireframing: -wireframe mode is in effect for window moves.
27/06/2021 11:20:56 If this yields undesired behavior (poor response, painting
27/06/2021 11:20:56 errors, etc) it may be disabled:
27/06/2021 11:20:56 - use '-nowf' to disable wireframing completely.
27/06/2021 11:20:56 - use '-nowcr' to disable the Copy Rectangle after the
27/06/2021 11:20:56 moved window is released in the new position.
27/06/2021 11:20:56 Also see the -help entry for tuning parameters.
27/06/2021 11:20:56 You can press 3 Alt_L's (Left "Alt" key) in a row to
27/06/2021 11:20:56 repaint the screen, also see the -fixscreen option for
27/06/2021 11:20:56 periodic repaints.
27/06/2021 11:20:56
27/06/2021 11:20:56 XFIXES available on display, resetting cursor mode
27/06/2021 11:20:56 to: '-cursor most'.
27/06/2021 11:20:56 to disable this behavior use: '-cursor arrow'
27/06/2021 11:20:56 or '-noxfixes'.
27/06/2021 11:20:56 using XFIXES for cursor drawing.
27/06/2021 11:20:56 GrabServer control via XTEST.
27/06/2021 11:20:56
27/06/2021 11:20:56 Scroll Detection: -scrollcopyrect mode is in effect to
27/06/2021 11:20:56 use RECORD extension to try to detect scrolling windows
27/06/2021 11:20:56 (induced by either user keystroke or mouse input).
27/06/2021 11:20:56 If this yields undesired behavior (poor response, painting
27/06/2021 11:20:56 errors, etc) it may be disabled via: '-noscr'
27/06/2021 11:20:56 Also see the -help entry for tuning parameters.
27/06/2021 11:20:56 You can press 3 Alt_L's (Left "Alt" key) in a row to
27/06/2021 11:20:56 repaint the screen, also see the -fixscreen option for
27/06/2021 11:20:56 periodic repaints.
27/06/2021 11:20:56
27/06/2021 11:20:56 Client Side Caching: -ncache mode is in effect to provide
27/06/2021 11:20:56 client-side pixel data caching. This speeds up
27/06/2021 11:20:56 iconifying/deiconifying windows, moving and raising
27/06/2021 11:20:56 windows, and reposting menus. In the simple CopyRect
27/06/2021 11:20:56 encoding scheme used (no compression) a huge amount
27/06/2021 11:20:56 of extra memory (20-100MB) is used on both the server and
27/06/2021 11:20:56 client sides. This mode works with any VNC viewer.
27/06/2021 11:20:56 However, in most you can actually see the cached pixel
27/06/2021 11:20:56 data by scrolling down, so you need to re-adjust its size.
27/06/2021 11:20:56 See http://www.karlrunge.com/x11vnc/faq.html#faq-client-caching.
27/06/2021 11:20:56 If this mode yields undesired behavior (poor response,
27/06/2021 11:20:56 painting errors, etc) it may be disabled via: '-ncache 0'
27/06/2021 11:20:56 You can press 3 Alt_L's (Left "Alt" key) in a row to
27/06/2021 11:20:56 repaint the screen, also see the -fixscreen option for
27/06/2021 11:20:56 periodic repaints.
27/06/2021 11:20:56
27/06/2021 11:20:56 XKEYBOARD: number of keysyms per keycode 7 is greater
27/06/2021 11:20:56 than 4 and 51 keysyms are mapped above 4.
27/06/2021 11:20:56 Automatically switching to -xkb mode.
27/06/2021 11:20:56 If this makes the key mapping worse you can
27/06/2021 11:20:56 disable it with the "-noxkb" option.
27/06/2021 11:20:56 Also, remember "-remap DEAD" for accenting characters.
