你好，我在Kylin(ubuntu)使用-unixpw时遇到一些问题，它不能正常工作，我在ubuntu18 20运行时它是正常的。

Hi, I have some problems with Kylin(ubuntu) using -unixpw, it doesn't work properly, it works fine when I run on ubuntu18 20.

24/08/2023 09:36:17 ------------------ USEFUL INFORMATION ------------------
24/08/2023 09:36:17 X DAMAGE available on display, using it for polling hints.
24/08/2023 09:36:17   To disable this behavior use: '-noxdamage'
24/08/2023 09:36:17 
24/08/2023 09:36:17   Most compositing window managers like 'compiz' or 'beryl'
24/08/2023 09:36:17   cause X DAMAGE to fail, and so you may not see any screen
24/08/2023 09:36:17   updates via VNC.  Either disable 'compiz' (recommended) or
24/08/2023 09:36:17   supply the x11vnc '-noxdamage' command line option.
24/08/2023 09:36:17 X COMPOSITE available on display, using it for window polling.
24/08/2023 09:36:17   To disable this behavior use: '-noxcomposite'
24/08/2023 09:36:17 
24/08/2023 09:36:17 Wireframing: -wireframe mode is in effect for window moves.
24/08/2023 09:36:17   If this yields undesired behavior (poor response, painting
24/08/2023 09:36:17   errors, etc) it may be disabled:
24/08/2023 09:36:17    - use '-nowf' to disable wireframing completely.
24/08/2023 09:36:17    - use '-nowcr' to disable the Copy Rectangle after the
24/08/2023 09:36:17      moved window is released in the new position.
24/08/2023 09:36:17   Also see the -help entry for tuning parameters.
24/08/2023 09:36:17   You can press 3 Alt_L's (Left "Alt" key) in a row to 
24/08/2023 09:36:17   repaint the screen, also see the -fixscreen option for
24/08/2023 09:36:17   periodic repaints.
24/08/2023 09:36:17 
24/08/2023 09:36:17 XFIXES available on display, resetting cursor mode
24/08/2023 09:36:17   to: '-cursor most'.
24/08/2023 09:36:17   to disable this behavior use: '-cursor arrow'
24/08/2023 09:36:17   or '-noxfixes'.
24/08/2023 09:36:17 using XFIXES for cursor drawing.
24/08/2023 09:36:17 GrabServer control via XTEST.
24/08/2023 09:36:17 
24/08/2023 09:36:17 Scroll Detection: -scrollcopyrect mode is in effect to
24/08/2023 09:36:17   use RECORD extension to try to detect scrolling windows
24/08/2023 09:36:17   (induced by either user keystroke or mouse input).
24/08/2023 09:36:17   If this yields undesired behavior (poor response, painting
24/08/2023 09:36:17   errors, etc) it may be disabled via: '-noscr'
24/08/2023 09:36:17   Also see the -help entry for tuning parameters.
24/08/2023 09:36:17   You can press 3 Alt_L's (Left "Alt" key) in a row to 
24/08/2023 09:36:17   repaint the screen, also see the -fixscreen option for
24/08/2023 09:36:17   periodic repaints.

24/08/2023 09:36:17 XKEYBOARD: number of keysyms per keycode 7 is greater
24/08/2023 09:36:17   than 4 and 51 keysyms are mapped above 4.
24/08/2023 09:36:17   Automatically switching to -xkb mode.
24/08/2023 09:36:17   If this makes the key mapping worse you can
24/08/2023 09:36:17   disable it with the "-noxkb" option.
24/08/2023 09:36:17   Also, remember "-remap DEAD" for accenting characters.
24/08/2023 09:36:17 
24/08/2023 09:36:17 X FBPM extension not supported.

******************************************************************************
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.

/dev/ptmx无论输入什么，总是返回“I”，我觉得问题可能在这里

google translate:

/dev/ptmx always returns "I" no matter what the input is, I think the problem may be here

24/08/2023 11:39:25 X DAMAGE available on display, using it for polling hints.
24/08/2023 11:39:25   To disable this behavior use: '-noxdamage'
24/08/2023 11:39:25 
24/08/2023 11:39:25   Most compositing window managers like 'compiz' or 'beryl'
24/08/2023 11:39:25   cause X DAMAGE to fail, and so you may not see any screen
24/08/2023 11:39:25   updates via VNC.  Either disable 'compiz' (recommended) or
24/08/2023 11:39:25   supply the x11vnc '-noxdamage' command line option.
24/08/2023 11:39:25 X COMPOSITE available on display, using it for window polling.
24/08/2023 11:39:25   To disable this behavior use: '-noxcomposite'

24/08/2023 11:39:25 Wireframing: -wireframe mode is in effect for window moves.
24/08/2023 11:39:25   If this yields undesired behavior (poor response, painting
24/08/2023 11:39:25   errors, etc) it may be disabled:
24/08/2023 11:39:25    - use '-nowf' to disable wireframing completely.
24/08/2023 11:39:25    - use '-nowcr' to disable the Copy Rectangle after the
24/08/2023 11:39:25      moved window is released in the new position.
24/08/2023 11:39:25   Also see the -help entry for tuning parameters.
24/08/2023 11:39:25   You can press 3 Alt_L's (Left "Alt" key) in a row to 
24/08/2023 11:39:25   repaint the screen, also see the -fixscreen option for
24/08/2023 11:39:25   periodic repaints.

24/08/2023 11:39:25 XFIXES available on display, resetting cursor mode
24/08/2023 11:39:25   to: '-cursor most'.
24/08/2023 11:39:25   to disable this behavior use: '-cursor arrow'
24/08/2023 11:39:25   or '-noxfixes'.
24/08/2023 11:39:25 using XFIXES for cursor drawing.

24/08/2023 11:39:25 Scroll Detection: -scrollcopyrect mode is in effect to
24/08/2023 11:39:25   use RECORD extension to try to detect scrolling windows
24/08/2023 11:39:25   (induced by either user keystroke or mouse input).
24/08/2023 11:39:25   If this yields undesired behavior (poor response, painting
24/08/2023 11:39:25   errors, etc) it may be disabled via: '-noscr'
24/08/2023 11:39:25   Also see the -help entry for tuning parameters.
24/08/2023 11:39:25   You can press 3 Alt_L's (Left "Alt" key) in a row to

24/08/2023 11:39:25   than 4 and 51 keysyms are mapped above 4.
24/08/2023 11:39:25   Automatically switching to -xkb mode.
24/08/2023 11:39:25   If this makes the key mapping worse you can
24/08/2023 11:39:25   disable it with the "-noxkb" option.
24/08/2023 11:39:25   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.

我想应该添加类似这样的代码 handle: runge's Password: ，因为虚拟终端输出的是 "InputPass Password:"
