Ok. I see from the earliest posts in this thread the size is quite a bit larger than what I was using.

Also, any way to get rid of the "sleeping" and "powered off" words that appear on screen so only the images appear?

if your image is large enough and not transparent in that area, the image will replace it

Thank you!

Best image size as you specified way back on page 1 of this thread is:

1080 x 1440

And here's one of the screensaver images on my Kobo

Just wanted to report another successful install of KoboRoot-ScreenSaver-20181216.zip on a Kobo Forma with firmware 4.12.12111 (and some patches)


Some things that may help other people in getting it to work:
- it took me a great number of sleep and power-off cycles (I'm guessing 8-10) before both modes were successfully scanned, i.e. don't give up/uninstall, just use your reader and it may start to work after a while
- especially the power-off scanline took a long time to register after the actual power-off event (I probably was too impatient on the initial cycles)
- sleep and power-off via the timed events (in settings) seemed to work better than via power button presses, I used sleep after 5 mins, power-off after 10.
- for the Forma, full screen images should be 1440x1920

My scanlines, for possible reuse (I checked and these are the same as the ones posted by @MGlitch for his Forma, so reusability seems likely, esp on the same firmware):
Spoiler:
Code:
standby=1649:ffffff000000ffffff000000fffffff5f5f5000000636363ffffffd5d5d57878781b1b1b0000002a2a2a7e7e7edadadaffffffd5d5d57878781b1b1b0000002a2a2a7e7e7edadadaffffffecececcbcbcbaaaaaa898989686868474747262626050505000000777777fffffff5f5f58585851515150000002a2a2a989898ffffffe2e2e2c2c2c2a2a2a2838383636363434343232323030303000000686868fffffff5f5f5d3d3d3b1b1b18f8f8f6e6e6e4c4c4c2a2a2a080808000000636363fffffff2f2f2767676222222000000030303656565e5e5e5ffffffb8b8b8505050050505000000020202535353a4a4a4f6f6f6f9f9f9ffffff

Finally, @frostschutz: when the scanline for sleep/standby was already registered in screensaver.cfg but the one for power-off wasn't detected yet, I still got scanlines when the device went into sleep mode (before going into power-off). This is not a big problem but it was unexpected, so I thought it might point at something special in the Forma context? Although I saw the scanline on the screen, the actual code for standby in screensaver.cfg was not changed/added (at least the time-stamp in the corresponding comment wasn't).

The thing is, I simply don't have a reliable method to detect standby/poweroff anymore. Not without going deeper into the rabbit hole, anyway, i.e. without LD_PRELOAD or outright patching of things. Which I want to avoid, since it would make the mod very firmware dependent (patches have to be re-done all the time).

So, screensaver addon doesn't KNOW AT ALL you're going into standby, or poweroff, or what. That's why the roundabout method of using a scanline in the first place. I have to look at the screen contents in order to be able to tell what is happening.

What I do know is when the reader was rebooted (due to service restart, time discrepancy, etc.). So what the addon does for the poweroff scanline is... keep detecting scanlines. And after reboot, simply use the last scanline that was done and assume it happened just before poweroff. So that's the poweroff scanline for you, and that's why it keeps on doing the scanline thing, it's just waiting for that poweroff to actually happen at some point.

It's a hack, a very roundabout method to do things, but - once the correct values are found - it works. Yay

Thanks for your feedback

Same firmware (sometimes across firmwares if they didn't change the sleep screen any), same language, and if there are any patches regarding borders, system font (sizes), etc. If it changes a single pixel in the scanline row, you need new values unfortunately...

For thoose who like the same kind of images than me, here are some links.
49 pictures. The poweroff version is the same than standby version but textured.
The links will be destroyed after one month without any download.

Hi frostschutz, I use the screensaver with a great pleasure.

May I suggest an evolution ?
I use a pin code to activate my Kobo.
When I turn it on or awake it, I have to type my code. If I decide to go back to sleep before I type all the code, the screen turn to blank but not to an image.

Do you think you can adapt your script ?
Hope I'm clear ...

I've never used the pin code before... unfortunately, at first glance there does not seem to be an easy fix for this.

Thanks for your quick answer.
If you can do something one day, it will be good, but don't worry about it.
