Installation / Removal

• Download the attached zip file
• Connect your Kobo to your computer
• Extract the file KoboRoot.tgz from the installer / uninstaller folder
• Copy it to the .kobo folder on your device
• Safely remove the USB storage and unplug
• Your device will reboot automatically

Control nightmode
There are two ways to control this mod:

• Long-press the LIGHT/HOME button to toggle on/off
• Use a launcher to start the nightmode.sh script:
  • KoboLauncher: Add:
    Night Mode = /mnt/onboard/.kobo/nightmode.sh
    to .kobo/KoboLauncher/kobo_launcher.ini
  • or KoboTweaks: (not working on 2.6+) Add:
    Night Mode=tweaks.executeSystemCmd(\"/mnt/onboard/.kobo/nightmode.sh\")
    to .kobo/kobotewaks.ini

Configuration
In your .kobo folder, there will be a configuration file called nightmode.ini. You can change whether the state should be retained over a restart of the device, the default state after power up and the duration for a long press. The new setting will take effect after a restart.

FAQ

• I have updated my firmware and it stopped working!
  Simply install the mod again
• Will this drain my battery?
  The effect on battery life should be negligible
• I can see more ghosting when the mod is activated!
  This is normal, as eInk screens are optimized for black-on-white mode. Change the refresh rate if it annoys you.

Is there no "patch" on Kobo?

I'm afraid I don't understand, what do you mean?

[Tiburscyo]

No problems in the transition of pages or reboot

once again, thanks KevinShort

[Lucas Malor]

Well you're right... :-P I mean the unix program

A little while back I release a very hacky white on black display mode for the Glo. Not long after, yoq put together a much nicer version of the hack, which you can download here.


Installation - for firmware version 2.5.1 ONLY!

A word of caution: This hack could potentially cause your Glo to not boot. If that happens, a factory reset (hold the light button while turning on the device) should resolve any issues. Also, this installer is specifically for firmware 2.5.1. It may or may not work on other versions.

You'll need to install the Kobo Tweaks plugin and create a new file named "kobotweaks.ini" in the .kobo folder on your Glo. Put these lines in kobotweaks.ini:

[Global]
compatFirmware=2.5.1

[CustomCommands]
Toggle Night Mode=tweaks.executeSystemCmd(\"/mnt/onboard/.kobo/nightmode.sh\")

Download "gloNightMode.zip", below. Extract it and put the KoboRoot.tgz file in the .kobo folder on your Glo. After your Glo reboots, open the Library to activate the plugin, then go back to the home screen. Under the "Tools" menu you can now select "Toggle Night Mode" to turn the hack on and off.

Kevin, this looks brilliant - and indeed I guess it would be even more useful for non lit devices - is there any chance it could work on the Mini: if there is, I am happy to play guinea pig!

Thank you yoq and KevinShort for your impressive work!

Yoq, may I ask you if you could set the resolution values depending on the respective device (800x600, 1024x758, 1024x768, 1440x1080), if you find the time. For establishing the device one could maybe follow the model used in /bin/kobo_config.sh.

KevinShort, you are my new hero!

It works like a charm!

That should be possible, I just have a Glo here though, so you'll have to be my tester on other models

Thank you for the quick response. I can try on my Touch.

and I will definitely try on my Mini

Ok, it should now read the actual resolution on startup and should work on the Touch and the Mini. Just replace screenInv.so and reboot.
If it doesn't refresh properly, send me the content of /tmp/screenInvertLog this might help me find the bug.

Thank you very much for the great program. Works nicely on the Touch. On a side note, I am still on FW 2.4.0.

As for the log file, it might perhaps be more convenient to have it on the user partition.

sorry, as a non-techie: do I just ignore Kevinshort's file, or do I first have to intall his and then replace his screenInv.so with yours?

[ShellShock]

Anyone tried this on the Aura?
