Ok got it working now even on the 4,5,9587 FW and usbnetwork works in both pbchess and KSM menu.
The problem was that i did not change the port from 5900 to 5901 on the vnc server/s.
I guess i assumed that a vncviewer that you can´t choose port with command line arguments would use the standard vnc port 5900.
Grrr!

Now the problem is it looks really really bad and is hard too read.
If you for example scroll one line the text becomes almost impossible too read scroll one more line and you can´t even see that it is supposed to be text.
Pictures are even worse.
And i have setup the kobo resulution on windows (so the kobo screen is used all the way).

If i try running kvnc with the no dithering mode it gets a bit better the text is then readable (as long as the text is black or white on a black or white background) but anything that have any greyscale or color is really still really bad.
Have tried with medium and fast mode too (and combined with dithering) but it only gets ALOT worse.

I assume this has something too do with it.

Code:

[root@(none) ~]# cd /mnt/onboard/kvncviewer
[root@(none) kvncviewer]# ./luajit vncviewer.lua -password bulldozer 192.168.2.1
00:1
could not open input device /dev/input/event2 (possibly harmless)
04/08/2017 09:14:54 VNC server supports protocol version 3.8 (viewer 3.8)
04/08/2017 09:14:54 We have 2 security types to read
04/08/2017 09:14:54 0) Received security type 17
04/08/2017 09:14:54 1) Received security type 2
04/08/2017 09:14:54 Selecting security type 2 (1/2 in the list)
04/08/2017 09:14:54 Selected Security Scheme 2
04/08/2017 09:14:54 VNC authentication succeeded
04/08/2017 09:14:54 Desktop name "nuckan ( 192.168.2.100, 192.168.1.103 ) - application mode"
04/08/2017 09:14:54 Connected to VNC server, using protocol version 3.8
04/08/2017 09:14:54 VNC server default format:
04/08/2017 09:14:54   32 bits per pixel.
04/08/2017 09:14:54   Least significant byte first in each pixel.
04/08/2017 09:14:54   TRUE colour: max red 255 green 255 blue 255, shift red 16 green 8 blue 0

And then specifically the 32bit and true color crap.
I do get the same 32bit/true color on on ultravnc/thightvnc/realvnc (on windows).
And from what i have learned there is no arguments that can set the resulotion/bit/color/etc on windows like there is on x11vnc/xvnc.
Is that right?

I do want too run windows on my nuc that is the machine i would use the kobo as a screen for.
But i guess i could do linux if there is no fix for the crap looking graphics on win.
But it would probably take days or even weeks to get linux setup the way i need it, and that does not include xvnc if that decide to not wanna play ball.

So i assume i have too change something (or a bunch) in the kvnc lua files.
Have not tried that yet and probably do not have time for 1-3 days.
So if anyone now what/where too change and in what file(s) that would be appreciated.
