Also, it seems that several of them are images I've SEEN it display, so I know it's able to, even if it doesn't like to. It also seems strange that it would do it EVERY time I let it sleep by itself, since if it's only certain images that are breaking it, it ought to land on an acceptable image at least SOME of the time...

@TheMongoose: The sneaky thing is that as soon as it hits something it doesn't like, everything is broken until a reboot, so it's not always fun to diagnose :/

I'm usually using The GIMP when I need an UI, or ImageMagick when I don't .

For simple command-line usage, I mostly use ImageMagick, more specifically, its identify command:
Code:
ixtab@mbp:/tmp/cm$ identify a_none.png 
a_none.png PNG 758x1024 758x1024+0+0 8-bit PseudoClass 256c 31.6KB 0.000u 0:00.000
Other than that: gimp (but that's probably overkill).

Well, it would seem that it was indeed some image(s) or other which were causing the problem. I removed all but one known to work and it seems to work fine, even when allowed to set its own bedtime. Unfortunately, I can't make heads or tails of ImageMagick, so it would seem I'm stuck adding back a few at a time and testing the hard way, then discarding those that don't work .

@TheMongoose: If you can, run all your images through identify, the expected output should be something like what ixtab posted (the key parts being the resolution: 758x1024, and the format: PNG 8-bit 256c).

A simple batch job will probably be the quickest way to do that.

Hopefully, @srm's issue will also be fixed in the next release, which should make the cover mode much more lenient with old/broken mobi files, and try harder at using *someting* as the cover. For those files, in might not always be the actual proper cover, but in most cases, it will be .

Err, I'm afraid you're going to have to simplify it further still, as I'm barely a neophyte when it comes to that kind of stuff. I've made a batch file once before to get around an obnoxious startup issue for a game, but I had step by step instructions :S. By the way, thank you both for your help, it is greatly appreciated, if poorly understood.

@TheMongoose:

Running a simple batch script from a terminal in the screensavers directory should do the job.

So, paste this into an id.bat file in the screensavers directory, and double click it.

Code:
@echo off
for /r %%i in (*) do identify %%i
PAUSE
Then pore over the output until you spot a file that looks wrong .

Just a quick note, my kindle ran an auto update that stopped my custom screensavers. At version 5.3.6 now I was afraid that the jailbreak was messed up too but after rerunning the screensaver hack the custom screensavers were back. No need to downgrade versions or rejailbreak. It was very easy and I think shows how strong the jailbreak methods you guys have created really are.

Parts of the jailbreak should be re-installed after a firmware update.
Directions: https://www.mobileread.com/forums/sho...d.php?t=198446

We also support various methods to control and/or prevent the forced OTA updates.
You might want to install one or more of them.

Err, *whistles*...

ScreenSavers 0.14.N?

Fix a tiny bit of what should have been fixed in 0.13.N regarding the cover detection, and a preview KUAL button for the cover mode.

I'm back :S. Things seemed to be working well for a while again, but now my kindle seems to have just kicked out the screensaver hack entirely and gone back to the default screensavers. I haven't connected to wifi or anything lately, and haven't done anything differently, it just decided to start using them again. What do?

@TheMongoose: Check your FW version, that sounds like an update...

The only other way you'd get the default screensavers is if you emptied your linkss/screensavers folder.
