Want to rotate through screen savers automatically

Eradicatore · 04-02-2014, 08:09 PM

Hi,
I have a jailbroken PW2 with the screen saver hack working great. I wanted to rotate through the screen savers periodically though, since I want to show quotes on it and hang it on the wall. So I searched around today and saw a thread mentioning that the screen saver only changes when you timeout or push the button to lock the kindle PW2. So I have some questions:

1) could I write a python script to do this rotation?
2) or would it be faster to learn the screen saver hack and try to add periodic rotation in the binary there?
3) Do I need ssh and usbnet to run python scripts on the PW2?

Thanks for any tips or ideas!

Justin

1. Yes, but you would have to install python first. Also, I think you could do the same thing in shell or C.

2.?

3. No, but it would probably help.
Also, welcome to Mobileread!

EDIT: If you draw to the screen then update the screen, the screen will update.

There's a good reason why it's not implemented: doing it the 'right' way would imply replicating the ads behaviour, and I have no idea how to do that, plus, it's not portable.

Doing it the bad way would make bypassing the ads trivial, so I won't do it either.

Plus, that would imply handling the 'device is asleep' issue, an issue which was tackled only very recently (https://www.mobileread.com/forums/sho...d.php?t=236104).

Thanks all for the replies! And thanks for the welcome PieMan! Also I got the tip to start at the k5 hacks wiki. That really helped me get started in this whole world of kindle hacking. So I just tested usbNet Hack and was able to kinda do what I wanted manually at the CLI like this:

[root@kindle /]# /usr/bin/lipc-set-prop com.lab126.powerd powerButton 1

Do that twice and it will get me a new image. Not the prettiest, but at least it's a start. I'll keep learning. Thanks again for helping a NOOB.

NiLuJe,
Thanks! I got time to read through the link you shared. That's even better. Just what I was looking for! Need to work on my searching skills I guess. :-) So I'll play around with eips and see how that works out. I may try to use the eventHandler hack also to just run the script to periodically run eips. At least that's my hope right now.

Note to self. Don't forget to actually follow the instructions and remove transparency from the gray scale images. Its great when the screen hack does this for you until you want to try eips yourself. LOL!
