Koreader running on Kobos (all of them, hopefully!) - Page 224

Coqisimo · 10-01-2021, 08:07 PM

Hi guys,

i am new to ereaders and to koreader, i got myself a Kobo Libra h20 a few days ago.
I was trying to learn all the options in my koreader until i reach to the "developer options" and i believe that i may have change some of them by mistake, i have tried to find something in the documentation but it seems that is non existant, i am trying to find the original/stock configuration for that developer options or an explanation on what each of them does.

so i have this ones active at the moment:
-Disable SW dithering.
-Bypass the WAIT_FOR ioctls
-Enable CRE call cache (With stats).

thank you in advance for any help

If they had one they wouldn't be developer options but just options!

I think CRE call cache is the only one that's enabled by default, but not with statistics (that's a long-press toggle, kind of unique and unexpected in the UI).

I just discovered a great use for the Autoturn feature! No need to mask up and go outside for my exercise now, woohoo

Frenzie · 10-09-2021, 04:36 PM

Seems a bit stressful.

I work nights seated answering phones, sleep most of the day, I gotta grab some sort of movement somehow, Autoturn a real boon for this

Frenzie · 10-10-2021, 05:52 AM

I'd just put on a podcast (or an audiobook) or something.

Whereas I would rather perform DIY dentistry with a rusty spoon than listen to any podcast or an audiobook (immersive non-L1 reading excepted)

Got my Sage today, looks like 2021.10.1 doesn't work with it (just crashes and goes back to the Kobo home screen on launch).

1. Is it expected to not work right now, or should it work and I'm doing something wrong?

2. Is there any useful information I could provide that would help out anyone who's working on making it work?

Yes, please paste the crash.log.

Frenzie · 10-22-2021, 12:09 PM

In a bit more detail, we don't currently have any kind of generic device or autodetection because they're just too different.

https://github.com/koreader/koreader...e.lua#L98-L110
https://github.com/koreader/koreader....lua#L237-L267
https://github.com/koreader/koreader...lua#L972-L1010

If you're lucky, it's just a matter of cobbling together something from what already exists, at least for basic (possibly suboptimal) functionality.

Frenzie · 10-22-2021, 01:53 PM

If you're willing to play around a bit, find the .adds/koreader/frontend/device/kobo/device.lua file, and replace these lines:

https://github.com/koreader/koreader...ua#L1006-L1007

with:

Code:

elseif codename == "cadmus" then
    return KoboEuropa

It probably won't work, but who knows, it just might.

You could try the same thing for several of the older models (going up from the bottom), but presumably the Elipsa is the best bet.

frailtyy · 10-22-2021, 03:33 PM

I have a Kobo Libra H2O that I've been running KOReader on after liking it on an older Kindle Paperwhite but I seem to have some trouble waking it occasionally, requiring a long hold on the power button to shut it off. Has anyone bumped into this and found a potential fix? If not, I'll probably just head over to the GitHub and post a formal issue but I don't get a crash, just an unresponsive sleep.

NiLuJe · 10-22-2021, 04:23 PM

@frailtyy: The Clara/Forma/Libra lineup is subject to potentially weird and random (-ish) kernel crashes (that the Libra 2 may inherit: surprise!

).

It's the first time I've heard of it happening during sleep, though. A verbose debug log might help (but it probably won't). I've been unable to pull out anything usefull (or, well, at all) out of my Forma when it crashes (I fear it'd require live serial access at the time).

NiLuJe · 10-22-2021, 04:25 PM

@all: I'll look into the Sage sometime next week (fnac failed to deliver mine on release day

).

Much like what happened with the Libra 2 over in the Kobo forum, I expect things to mostly work, we just have to figure out the native rotation.
(Unfortunately, the tools I recommended to do that on the Libra 2 don't really do anything useful on sunxi SoCs, so, better just wait. Unless someone wants to get me a strace of nickel

).

Oh, I also fully expect Wi-Fi to require extra weird shenanigans in at least one of those.
