NickelMenu: An integrated launcher for Kobo eReaders

[Falafelteller]

I have tried Nickelmenu on my Kobo Libre Colour, I enabled telnet but I can not log in.
I tried with username root and empty password but it won't log me in. Any advice? whats the password?

Hi all, I have adapted the battery script to Libra Colour :
- found correct path
- commented out empty lines (they generate error messages on Libra Colour, weird ?)

The result is attached.

Here is the script :

# Battery Statistics Calculator 1.1 (2024-05-25) by Aleron Ives
#
# This script calculates battery statistics for the Kobo Libra 2.
# (adapted for Libra Colour : see v_pct")
# (adapted for Libra Colour : "bd71827_bat" instead of "battery" in path)
# Check the contents of /sys/class/power_supply/ if you use a different
# model to ensure that the statistics you want to track are available.
#
# You can use NickelMenu to invoke this script like so:
# menu_item :main :Battery :cmd_output :500 :/mnt/onboard/.adds/battcalc.sh
#
# Gather the necessary statistics
#
meter=$(cat /sys/class/power_supply/bd71827_bat/capacity)
v_now=$(cat /sys/class/power_supply/bd71827_bat/voltage_now)
v_min=$(cat /sys/class/power_supply/bd71827_bat/voltage_min)
v_max=$(cat /sys/class/power_supply/bd71827_bat/voltage_max)
c_now=$(cat /sys/class/power_supply/bd71827_bat/charge_now)
c_full=$(cat /sys/class/power_supply/bd71827_bat/charge_full)
c_dfull=$(cat /sys/class/power_supply/bd71827_bat/charge_full_design)
#
# Format the statistics
#
#let v_pct=$v_max-$v_now; let v_pct/=7000 # Calculate charge percentage from V - Libra 2
let v_pct=$v_max-$v_now; let v_pct/=9000 # Calculate charge percentage from V - Libra Colour
let v_pct=100-$v_pct # "
let v_now/=1000; let v_min/=10000; let v_max/=10000 # Convert to V
let c_now/=1000; let c_full/=1000; let c_dfull/=1000 # Convert to mAh
let v_nowr=$v_now%1000; let v_now/=1000 # Simulate floating-point arithmetic
let v_minr=$v_min%100; let v_min/=100 # "
let v_maxr=$v_max%100; let v_max/=100 # "
let charge=$c_now*100/$c_full # Calculate charge percentage from mAh
let c_health=$c_full*100/$c_dfull # Calculate health percentage from mAh
#
# Display the results
#
echo Capacity: $c_now mAh / $charge% / $meter%
echo Voltage: $v_min.$v_minr V / $v_now.$v_nowr V / $v_max.$v_maxr V / $v_pct%
echo Health: $c_full mAh / $c_dfull mAh / $c_health%

Thanks, that worked.

Has anyone already tried NickelMenu on the tolino shine 5? Since the firmware v5 no longer recognizes KoboRoot.tgz, is renaming enough? Or should one keep one's hands off it at the moment?

It needs a different build for qt6... it won't even load if you try it.

Right, QT6... I was (also) afraid of that. Thanks for clarifying this.

I know I'm late to the party, but i found a solution to solve this issue: I've added a chain_always command after the dark mode toggle that runs a shell script:

menu_item : reader : Toggle Dark Mode : nickel_setting : toggle : dark_mode
chain_always : cmd_spawn : quiet : exec /mnt/onboard/.adds/misc/DarkModeHelper.sh

And here's the script:

#!/bin/sh

KOBO_CONF="/mnt/onboard/.kobo/Kobo/Kobo eReader.conf"

if grep '^DarkMode=true' "$KOBO_CONF"; then
ioctl /dev/ntx_io 241 -v 1
sed 's/^FrontLightLevel=.*/FrontLightLevel=1/g' <"$KOBO_CONF" >"$KOBO_CONF".tmp && mv "$KOBO_CONF".tmp "$KOBO_CONF"

elif grep '^DarkMode=false' "$KOBO_CONF"; then
ioctl /dev/ntx_io 241 -v 5
sed 's/^FrontLightLevel=.*/FrontLightLevel=5/g' <"$KOBO_CONF" >"$KOBO_CONF".tmp && mv "$KOBO_CONF".tmp "$KOBO_CONF"

fi

This way, every time you toggle Dark Mode, there is a check to determine whether dark mode has been turned on or off ; it then changes the level accordingly in ioctl AND in "Kobo eReader.conf", so that the level changes persist across reboots.
