Updated 24 January 2022 to reflect the new version of Nickel Menu
With firmware 4.28.18220 and above, the old
Invert Screen mode has been replaced with a new
Dark Mode; this works on not just the latest Kobo models (Elipsa, Sage, Libra 2, and Nia) but on older models as well (such as the Aura, Clara HD, and Libra H2O).
The old invert mode worked on all screens, and inverted everything including images and book covers; the new one works only in books and articles from Pocket, but does not invert images or menus.
To enable it and be able to toggle it on and off from your device, you should install Nickel Menu.
If you already are using an older version of Nickel Menu, copy your menu file from KOBOeReader/.adds/nm to a safe place on your computer, then completely delete this folder: KOBOeReader/.adds/nm. It will be automatically recreated when your Kobo reboots after you safely eject it.
Now, get
version 0.5.4 of Nickel Menu from here (or a later version, when one is released);
DO NOT use an older version (that is, do not use any Nickel Menu release with a lower version number than 0.5.4):

Download the KoboRoot.tgz file from the GitHub link and copy that to this folder on your Kobo:
KOBOeReader/.kobo. (You may need to show hidden files to see the folder.)
Now, follow the instructions in the first message here to set up Nickel Menu:
https://www.mobileread.com/forums/sh...d.php?t=329525
Then, add these lines to your Nickel Menu configuration file (I call mine config-nickel-menu):
Code:
menu_item :main :Dark Mode :nickel_setting :toggle :dark_mode
menu_item :reader :Dark Mode :nickel_setting :toggle :dark_mode
After ejecting your device, you'll have a Dark Mode toggle listed on your Nickel Menu men.
