A VNC viewer for ebook readers

kindlevncviewer's Issues

Key-events "bleed through" to Kindle user interface on K3

I am using this on K3 and have a problem, that did not occur with the non-jit vnc viewer:

When I have a running vnc connection on the K3 and I press a key, the key event is captured and sent to the remote machine as required.

BUT the key event is ALSO sent to the Kindle user interface (covered by the vnc viewer).

Say I press the arrow down key, the I see the line which marks the currently selected entry on the kindle start page "bleed through" the vnc image and move down the screen.

If I press enter, a ebook gets started (which then blocks out the vnc image until the vnc screen update), etc.

Is there any way to prevent the key event from being sent to the kindle UI? With the native version, this problem of the kindle UI reacting to keys pressed in the vnc viewer did not occur.

new version has race conditions (?) leading to a hanging app

Can it possibly be build and run on pocketbook ?

Or there are too many dependencies on kindle stuff?
For example pocketbook 840:
Linux 3.0.8

Kobo Aura HD 32bit fb ?

Hello and thank you for the great work.

I'm trying kvncviewer from the extracted zip file (1st post on mobileread forum) on my Kobo Aura HD (firmware 4.35.20400).
When I use files extracted from this zip file I get the error:

# ./luajit vncviewer.lua -password ahahah 192.168.1.51:1
./luajit: ./ffi/framebuffer_linux.lua:183: unknown bpp value for the mxc eink driver
stack traceback:

        vncviewer.lua:3: in main chunk
        [C]: at 0x0000bd31

A look at the kobo framebuffer gives:

# fbset

        # D: 0.008 MHz, H: 0.005 kHz, V: 0.003 Hz

        accel false
        rgba 8/16,8/8,8/0,8/24
endmode

I tried to add a condition for 32bit fb in framebuffer_linux.lua:

...

                        -- this ought to be a Kobo                                                                      
                        local dummy = require("ffi/mxcfb_kobo_h")                                                       
                        fb.einkUpdateFunc = kobo_update                                                                 
                        fb.bb = BB.new(fb.vinfo.xres, fb.vinfo.yres, BB.TYPE_BB32, fb.data, fb.finfo.line_length)       
                        fb.bb:invert()                                                                               
                        if fb.vinfo.xres > fb.vinfo.yres then                                                           
                                -- Kobo framebuffers need to be rotated counter-clockwise (they start in landscape mode)
                                fb.bb:rotate(-90)                                                             
                        end                                                                                             
                elseif fb.vinfo.bits_per_pixel == 16 then                                                        
                        -- this ought to be a Kobo                                                                      
                        local dummy = require("ffi/mxcfb_kobo_h")
...

I got the program to run and draw part of the VNC session screen on the flickering Kobo screen.
Nikel was not killed before trying that, maybe its interface interferes with kvncviewer display ? (and touch inputs ?)

The framebuffer settings I put in the above code is a quick and dirty trial to get the program running, but probably all wrong. Would you have suggestions on how to get a correct init of the display ?

I saw this issue: #4
Updating these files by the latest commit of kvncviewer did not help with the first error, so I guess the 32bit reported by fbset is the result of a firmware change between his version and the newest ?

I'll try to get a better control of the flickering (don't need quick updates or frequent fullscreen refresh, the screen I'm targeting is mostly static), and get the touch input to work, feel free to let me know if you have suggestions.

TightVNC server running on windows on port 5901.

Thank you for your help !

Publish binaries for K3

I am a long time fan of the old kindlevncviewer. I love the idea of the hackable lua version and tried to install it on my K3.

Unfortunately the release published on the forum is compiled for a different glibc version:

[root@kindle kvncviewer]# ./luajit vncviewer.lua
./luajit: /lib/libc.so.6: version `GLIBC_2.7' not found (required by ./luajit)

Is there any chance you could provide a K3 compatible binary release for the less tech-savy users?

Wrong pixel format on Aura HD

Hi,

as reported at http://www.mobileread.com/forums/showpost.php?p=2929418&postcount=22 I had to adjust a few things to get the “colors” correct on Aura HD.

makefile documentation is out of sync?

I know you are fiddling with the LUA stuff atm.

But "make" will just fail right now.

make kindlevncviewer

is the bare minimum.

Word the the wise and all that...

Kindle UI stays on screen after running shell script on Kindle Paperwhite 3

After I run ./kvncviewer.sh ..., the log shows that the connection was successful and that the display is updating, but the user interface still shows on the screen. This seems similar to #9 but instead of bleed-through, there is no VNC display on the screen.

Here's part of the output:
