Onyx Boox Kon-Tiki 2 (Nova3 platform) - apps

Re-enabling com.onyx and restarting doesn't help. I should probably let Onyx know

Yes, but you can see from the E in that report that it's a real error.
Onyx knew that they screwed up so they wrapped it in tissue paper (a try-catch) so it only prints a W warning.

Ah, I see. Thank you for clarifying.

Will these extra lines in the log actually make any difference to worry about?
I know the log files are rotated with some size limit, but still these extra write operations.

I just like this solution (long-press to call stock dialog) because it is simple and yet functional. I can adjust each level or locked together, select profiles and toggle lights from this dialog.

Before that I had GentleGlow on long-press, however to turn off the lights I had to go Notifications menu. Also, it is kinda separate from the stock brightness control, so other apps do not sync with it.

Android logs have become a sewer anyway with every single app and service wanting to spew something.

Yes, the system settings screen_cold_brightness, screen_warm_brightness are Onyx specific.
If you don't write to them the lights will not restore to the same level the next time you turn it on.

Me? I just leave the lights on at 30% all the time. If it's bright, I don't notice.
I haven't noticed battery drain. I almost never explicitly charge. It's connected enough for sync/dev.

Is there a safe way to shuffle screensavers (or make the system select them randomly) located in /data/local/assets/images/ ?

Currently the only way I see is to run a shell script that renames those “standby-n.png” randomly after boot completed. Magisk has a directory for such shell scripts. However I am not sure how will it behave.

I only tested it manually: via SSH, renamed the screensaver number that was supposed to be the next one (e.g. number 2 if I only put the device to sleep once after fresh boot). The substitution worked well. If the next file is not strictly named in that format (for example standby-2A.png), it uses some pre-cached stock image of 600x800 px. I replaced those in /system/media/ — but this didn’t change a thing. I don’t know where these pre-cached things come from, maybe from disabled com.onyx.
I should probably also make a check of chmod (777) for those files.

Are you actually modifying /system?
Right now all the updates (~1GB) seem to be full and not incremental, but if they ever switch to incremental it might make life more difficult if you've modified /system.
I saw that I had tried putting links in /system/media (but in Magisk, not /system) but that hadn't worked.
Now I just keep 3 copies of the same graphic in /data/local/assets/images.

I haven't found the place in the code yet where the names of 3 files are hard-coded.

Only those screensavers + swapped lock sounds for (un)lock.
I have the original copies though, so if the update doesn't work, I'll revert them before updating.

[Renate]

Yes, but even deleting A, deleting B, writing B, writing A changes the disk layout.

[mergen3107]

OK
If this will ever be a problem, I'll just edl the backed up untouched system.img

Answering my own question, here is how I managed to shuffle screensavers on each boot.
(As a reminder, since I disabled com.onyx, my screensavers are in /data/local/assets/images/ . This is a barebones screensaver engine, so I couldn't find any controls to it.)

1) Installed ccbins (Cross-Complized Binaries) module in Magisk. It installs busybox with a handful of utilities. My main goal was to get "shuf", to shuffle things in the array.

2) Wrote a script "shuffle_run.sh" and placed it in /data/adb/service.d which refers to another script "shuffle.sh" in /data/local/assets/ (giving chmod 755 to both of them as well). This file takes the names via ls (maybe not the best option, but it works), renames to a temp filenames and then renames again to the same names but taking a shuffled array of temporary names as input.

Files attached, if you wanna try.

Tested, works fine. I am happy

P.S. ccbins has a really good amount of utils. If ran from ssh (just "ccbins"), you can download more things like bash, zsh, tcpdump, htop, nano, and many others.

For those interested, I connected an Xbox Wireless controller to Kon-Tiki 2 and caught keycodes:

Button             | Code     | Action   |
-------------------|----------|----------|
Xbox button        | 0        | (nil)    |

Left stick button  | 106      | (nil)    |
Right stick move   | (ignore) | (nil)    |
Right stick button | 103      | (nil)    |
A                  | 96       | (nil)    |

RT                 | (ignore) | (nil)    |

D-pad and L-stick movements are hard coded as directional movement, so can't be reassigned.

Yes, they can.

That all comes out of /system/usr/keylayout/Generic.kl like everything.
I haven't played with them, but the joysticks are at the end of that file.
Most certainly the D pad can be make anything that you like.
You can even add a 10 key numeric pad and use it for non-numeric.

You want to make your own VID/PID specific keylayout.
You can make different peripherals respond differently as long as they are not the exact same device.

There has been an update to FW 3.1 on Feb 10 2022 at the Onyx website. On this FW, the CCW rotation for screensavers is no longer needed. Only the shutdown image must be rotated.

Hmm, so weird. Looks like Onyx has broken bootloader commands in the recent update. Unless it was me who did something stupid. I cannot do "fastboot flash boot boot.img" anymore. Right after this command, fastboot gets disconnected and I have to restart the device with power button. I still can access edl and replace boot partition there.

I am not sure when did this start, before or after update. I remember doing "fastboot flashing lock" to lock it, but doing unlock works OK as it seems.
