Thank you very much. you solved the problem for me. I launched the vncviewer in kterm. It can successfully connect with TightVNC server. However, It seems that I have a scaling problem. Not all the screen fits into kindle. In fact, part of the bottom and right part of the screen is cropped. I tried to change client_width and height in the file config.lua but nothing changed. Also, I set the screen resolution in server configuration.
What can I do for this?

Thanks for your help but adding this option just rotates the screen to portrait. The screen connects in landscape as default. My monitor is 1920*1080.
I tried to use:
./luajit vncviewer.lua -scale 2(and 0.5) 192.168.1.5:5900
but it didn't change anything

I follow your instruction to connect my raspberry pi to kindle paperwhite.
However, KTerm return:
ConnectToTcpAddr: connect
Unable to connect to VNC server

I try to connect raspberry pi to my window 10 laptop via RealVNC and it's Okay with no error message shown.

It seems like I do something wrong with my kindle setup, can anyone help me?

Can you ping the PIs address?

are you using a direct USB connection or Wifi? a direct USB connection to the PI requires some extra set up on the PI side to work propery.

Just sharing a working version tested on 5.16.2.0.1 for others. I am able to use my Android mobile screen(Apps like Eink Bro Browser(created for android e-ink readers),chrome are looking good on kindle screen).
Changes in the attachment:

1. Recent bug fix from Github(key-event) bleeding, fixes an issue where VNC touch events were getting propagated to kindle gui
2. couple of fixes from older responses in this thread, missing constants
3. recent fixes for newer versions of PW, to refresh the screen in an infinite loop
4. Working touch control

Usage:
1. Adjusting the screen resolution of android phone(will be acting as VNC server) to match the Kindle resolution

Log into Android shell using adb connect & use the below command:

wm size 1836x2448 :Kindle Scribe Resolution(need to be adjusted as per kindle model)

wm size reset :Should be executed, when mobile phone should be reset to it's original resolution

There are some applications available in play store, to adjust mobile screen resolution with out using adb tools on laptop.

2. I am starting VNC server on my mobile with application https://github.com/bk138/droidVNC-NG

3. Now I have a VNC server, which is providing the content in the resolution of kindle. Replace the IP address and Port from your VNC server(android) in the file: kvncviewer.sh

./luajit vncviewer.lua 192.168.23.12:5900

4. If any password is set in the VNC server, provide the same in the file:vncviewer.lua. Replace nil with "<yourpassword>" (including the quotes)
5. Lauch the vnc viewer from KUAL

How to exit from vnc viewer:

Option 1: Force Restarting the kindle(easiest option). Even when the VNC server is stopped on mobile, it is recommended to restart the kindle immediately, after using it as VNC viewer
Option 2: If you can do SSH into kindle, find out the parent PID of the kvncviewer.sh process from htop and kill the same using pkill -P $parent_pid

I would like to thank all the developers(creators) for their contributions and making our devices more productive.

Disclaimer: I am not responsible for any damage to the kindles. I just colated the files from different sources and wanted to share a working version(giving back to community). Setting up vnc viewer requires USB Networking(Wifi mode) working for this use case. If you want to use this application, be ready to be patient(time it takes to get it work for Newbie, is high) and doing your research.
