KUAL: Kindle Unified Application Launcher (v2.7) - Page 100

geekmaster · 03-24-2016, 06:14 PM

One thing folks seem to be neglecting when launching native mode apps (such as gmvid and myts) from KUAL, is to pause and resume the GUI framework, to prevent framebuffer contention from messing up the native mode output (accidentally drawing KUAL elements on top of the active native mode app video).

Here is a code snippet that did what all native mode apps need to do, extracted from my "rippleweave" script in my "eink algorithmic art" thread:

PHP Code:


			
lipc-set-prop com.lab126.powerd preventScreenSaver 1

killall -stop Xorg cvm # pause framework

eips -c -f



# insert native mode app launch here ...



killall -cont cvm Xorg # resume framework

lipc-set-prop com.lab126.powerd preventScreenSaver 0

This stuff should probably be inserted into the script that launches native mode apps in the KUAL extensions folders. I plan to do this for myts and gmvid and some of my demos ASAP...

I hope these commands still work on newer kindle firmware. I have no kindles newer that a K5 (Touch) since I lost my PW on a trip, nor can I afford any new kindles at this time. However, I have plenty of "debricked" K3g (K3 with 3G) demo devices, which I could trade for newer kindles to support my renewed interest in kindle development.

EDIT: Hmm... Not working on my K3. Investigation in progress...

Is there no x11 on a K3?

NiLuJe · 03-25-2016, 05:40 AM

Nope

.

geekmaster · 03-25-2016, 07:39 AM

I have it working. Pausing xorg on a k3 kicks a harmless error message, but is needed on newer kindles. I have a new gmvid kual extension, with multiple videos. It plays nice with kual -- no framebuffer contention. I will post it when I finish adding sound to gmvid (almost done, but toolchain issues at the moment). I am using A_LAW compression, after doing dynamic range compression to my audio track in audacity. The audio sounds great for what it is (as interpreted by my aging ears). I can only test audio on DX/DXG/K3/K5. Do any newer kindles have audio?

Still thinking of doing PWM audio on the accessory port (metal tabs to power booklight) on some models (such as K4), if it can be toggled fast enough.

I also have a gmdemo extension with multiple of my native mode graphics (and sound) demos, also with no framebuffer contention (pausing the framework as shown in a previous post above).

Or Yep! As in "Yes, there is no x11!".

The K5 is the most recent model with audio i/o support.

Although not all of the audio i/o code is gone, almost as if they are afeard of what would break if they took it all out.
Or maybe they just lost track of what all they put into the early devices.

IIRC, I **think** the most recent (and most expensive) KV model has a 'vibrator' in it to emulate tactile feedback for their virtual buttons.

If you PWM to that device - a person might be able to press the Kindle against their head and 'feel' the music.
People with a cochlear implant might find that interesting.

Hi,
I'm an absolute Newby in this forum.
Just got my new PW3 (G090G1****, FW5.6.5) jailbroken with the method of kaznelson:

>>>>>>>>>>>>>>>>>>>
If all contents of a folder "jb" from archive "jb.zip" copy in Kindle-root, and then to enter in an address line of browser this local address - jailbreak worked without problems:
file:///mnt/us/index.html

Tested in PW3 G090 with stock firmware 5.6.5, aeroplane-mode "on".
<<<<<<<<<<<<<<<<

Jailbreak worked fine, PW3 said jailbreak successful in the top line.

Did a complete restart after all finished.

Then I put KUAL-KDK-2.0.azw2 into documents folder and tryed to start it.
I found the Kindle Launcher Icon on start screen and tryed to start KUAL.

I got a message:
"This Device has not been authorized by the developer of this content as a test-kindle. Please contact developer."

Hope you can help me going on.

After using Branch Delay's jailbreak you need to install the hotfix which contains the jailbreak bridge in addition to the MKK (kindlet developer keys).

For details, such as the link(s) read the first post of:
https://www.mobileread.com/forums/sho...d.php?t=265675
It has been edited to be a bit more clear.

u831912 · 03-29-2016, 11:59 AM

Thanks a lot,

my mistake.
Thought i had to install KUAL and MRPI before installing the hotfix.
It's working perfectly now.
Just installed Python and Screensavers hack and it works fine.

Going to read a bit more in the forum to find more interesting things.

Thanks to all people working on these hacks.

Another noob here.....

Trying to use KUAL on on Kindle 2 (k2i). It is jailbroken as shown here: https://wiki.mobileread.com/wiki/Kind...26_4.x_Kindles.

I have KUAL loaded but when I run KUAL I get "The application is not signed by a registered developer."

What am I missing or what did I do wrong?

Thanks.

eschwartz · 04-03-2016, 12:25 AM

Did you install the MKK?

Remember to install the "backdoor lock" KUAL extension, and to lock the backdoor, or amazon will remove MKK when you disable airplane mode (leaving a "not a test kindle" book on your device, and making KUAL fail again).

NiLuJe · 04-04-2016, 02:25 PM

@geekmaster: That should only happen when changing the registration status of the device (and maybe tinklering w/ the key db manually, but if you're doing that, I assume you know what you're doing), not a simple networking toggle :?.
