I feel the only reason Amzn didn't include a version of x was implementing the 5 way in a meaningful manner. making it move the cursor is one thing. making that not be incredibly annoying as a process is quite another.

Using a mouse to operate a touchscreen GUI is annoying to some degree too. Just look at all the complaints about Win8's "The GUI formerly know as Metro".

Yep.

But this is the three. short of the nasty 90's overlays or ATTACHING A LEAP (OMG YES!!!!!!!!!!!!!!!!!!) it's a non issue


Did I mention I want to attach a leap? ;0

where /usr/local/bin/kvnc is:

TODO: get -create to do what I expect, or figure out something else.

(also link /usr/bin/egrep to /mnt/us/usr/bin/grep since some ancient stuff still calls it and 1.7.2 busybox doesn't support it) - I built the full Gnu Grep just to be doubly sure.

EDIT: added fun screeny

Looks like your making great progress there!

Thanks. SDL will be a hurdle via this method of course. (It also invokes console)

I'm thinking what would be required to just invoke the keyboard natively.

Seriously considering making a gaming kernel, with USB modules, and a fail-over rollback for the existing kernel / modules on uninstall.

It would make for a big hammer of a solution but if we could tie in all the improvements to one offering I think (since 3.4 is likely the last ever kernel release) we could have a decent - if overkill - solution to lots of questions.

Thoughts anyone? wasted effort?

hmm..

[root@kindle root]# /mnt/us/Xfbdev -fp /mnt/us/sh/fonts/X11/100dpi/ -noreset -nolisten tcp -screen 600x800x8

allows

[root@kindle root]# /mnt/us/kindlevncviewer/kvncviewer.sh dev:0

me@dev x11vnc -noxdamage -noncache -forever

which allows for keyboard input with the real x server AFAICT

but with odd results in the kvncviewer. I'll keep playing.

EDIT: (Don't need the visual feedback I think. duh) - yeah. just need the

[root@kindle root]# while usleep 90000; do echo 1 > /proc/eink_fb/update_display ; done instead

[twobob]

okay. so the logical conclusion of all that is...

since we can start the Xserver AND point x11vnc at it AND run xvncviewer.

[root@kindle root]# /mnt/us/Xfbdev -fp /mnt/us/sh/fonts/X11/100dpi/ -noreset -nolisten tcp -screen 600x800x8 -bs -wr

record: RECORD extension enabled at configure time.
record: This extension is known to be broken, disabling extension now..
record: http://bugs.freedesktop.org/show_bug.cgi?id=20500

IF xvncviewer could point to x11vnc started in a shared mode like:

[root@kindle lib]# x11vnc -noxdamage -noncache -shared -forever
[root@kindle root]# /mnt/us/kindlevncviewer/kvncviewer.sh kindle:0

and then on the PC: you could just "step in" to add control. like:

vnc <kindle ip or hostname>

where vnc was:

#!/bin/bash
xtightvncviewer -encodings "tight copyrect" -depth 4 -compresslevel 1 $@ &
sleep 2;
# make it tidy
wmctrl -x -r Tight -e 0,0,0,600,800
wmctrl -x -r Tight -b toggle,fullscreen

sadly this does not work as there appears to be some ZRLE (or perhaps just "expected" formatting) errors when trying this:

however - if working - this would present us with the best of all worlds.

EDIT: I had a dig around in the command line switches but nothing leaped out as really useful for further testing. would have to jump into the code.
(/mnt/us/kindlevncviewer/kindlevncviewer --help )

/mnt/us/kindlevncviewer/config.lua appears to be all key related.

so no obvious easy wins.

[knc1]

Ah, so close.
Cheer, cheer, cheer.

Nice progress. Yes, kindlevncviewer's CLI switches are horribly under-documented. They accept everything that libvncclient can handle. My guess was that x11vnc's ZRLE encoding was broken (didn't bother to debug), so I specified an encoding on CLI: "-encodings copyrect,raw" for kindlevncviewer. For all possible switches see here: http://libvncserver.sourceforge.net/...44eb97d2356475

Errm, are you using Xfbdev, als the command lines you quoted indicate? Because the setup I imagined was using Xvfb...

yep. works with Xfbdev as well as xvfb. so I have been testing both.

as the Xfbdev does not actually cause an eink update I was wondering about hacking your viewer "over the top" - on the device.

like err.. knvcviewer.sh 127.0.0.1:0 : )

Just playing around really to see what is possible.

works well, thank you mate.

TODO: Make monochrome Blackbox theme.

Feels like real progress now.

Heck yeah!

EDIT: impressively low load and footprints, all my apps are utterly unstripped and not built for size too.

Also. This is NOT with the framework stopped. merely a killall -STOP cvm. sweet!
