vnc viewer for KPW2

On the RasPi, you'll likely want to switch to x11vnc at some point if you want to use keyboard/mouse connected to it. For now, vncserver (Xvnc) will work fine. I hope the space between ":" and "1" is just a quotation error?

Errrm - you *did* set up USB networking and tested it, right? So you're sure the IP addresses are set up properly and you can make connections? Checked the firewall, as twobob suggested?

Yes , It said a VNC server is running :1 on the Raspi. I did again with no space between ":" and "1". But it requires password. How to do next?

Please answer my questions. Like whether you did set up USB networking.

Also, read the documentation of the software you use. When you run kvncviewer without any options, it will print help messages explaining how to specify a password. Alternatively, don't run your VNC server with a passwort requirement. Again, look into its documentation.

Ok. I am always typing on KPW2 to control Raspi by SSH. There is no USB networking problem between them.

I was following with the site:
https://www.mobileread.com/forums/sho...14&postcount=3
But I don't know about the NOTES:ssh root@<kindleIP> "while :; do eips ''; usleep 90000; done;"
Besides, I type /mnt/us/kindelvncviewer/kvncviewer.sh in kterm. It only said "Couldn't convert 'config.lua 'to host address" and some about "/proc/keypad".

And I was trying to add password before the hostname. Rusulted in "...event on fd #5"and "partially updating eink display (0.46)-(11.71)"continually. ?_?

That's good, you're almost there then. Now, only the refresh loop is missing. You've cited it above (that while... loop). You will need to run that in the background. Please accept that you need to learn about what you're doing. It is not end-user ready software by any means.

Would I run the codes "while :; do eips ''; usleep 90000; done;" on kterm? Is there a example?

Not if your using the screen to display something non-kterm.
Enter that command from the ssh terminal connection into the kindle.
(You can have multiple ssh terminal sessions open to the kindle at the same time - this is *nix, not one of those O.S. that you have to pay-per-user session.)

Yes:
while :; do eips ''; usleep 90000; done; &
that is eips followed by two(2) single quotes
That refreshes the screen

Not good, I ssh the KPW2 via wifi and run the codes . Then I run kvncviewer on kterm but it showed little of the desktop and still said "partially updateing eink display (757,742)-(616,767)"

How to test it?

[hawhill]

If you see a (however small) part of the desktop, it basically works. kvncviewer will spit out *lots* of these "partially updating eink display" messages. That's normal debugging output, not an error.

If it stops at that point, well, you might be running into the aforementioned problem that's left in kvncviewer. Except for further debugging its code, I have no suggestions left, sorry. I can't really give an estimate when I would eventually get to work on the code myself again, as I'm terribly short of spare time, sorry :-(

As the Kindle Touch devices do run an X server, however, I encourage you to try an X11 based VNC viewer, too. I think nobody here did yet, but it might be easier to get that running than to debug Lua/C code in kvncviewer - depending on your background :-) I'm not aware of a packaged version, though.

How to creat shell script on the kpw2 and get updates as I edit ti on Windows ?
Cited:
"while :; do eips ''; usleep 90000; done;"
"wrap the same above code in a named shell script on the kindle and call/kill that to get updates."

I run x11vnc on Raspi and got the desktop on KPW2 ,but there is a problem of a screen resolution. It is small, and I cann't find out how to change it.

Is it the thing in /etc/X11/xorg.conf.d/calibration.conf ?
And why the monitor it detected is 320x240?

You **can** run more than one ssh session at a time.

On the machine you use for the client - just open **another** terminal window and ssh into the Kindle **AGAIN**.
Leave the kindle's display free for use as the vnc viewer (no kterm running on it).

Err, what I want to do is using the vncviewer on kindle without using computer to ssh into it to ruan the codes at the same time.

Besides, why I using the X11vnc on Raspi and the desktop displayed on kindle is very small like the shape of the stamp. Although I can control with keyboard and mouse, the display setting on Raspi desktop said the monitor it detected is 320x240? And can I change it ?
