How to enable night mode for Calibre in Manjaro Linux

Manjaro Linux i3 ships with a dark theme setting by default.

Something I really appreciate.

When you install Calibre and execute it, you’ll find thatit doesn’t use the system’s theme.

However, telling it to do so is really easy.

You just need to set the CALIBRE_USE_SYSTEM_THEME env var, like this:

echo -e '\nexport CALIBRE_USE_SYSTEM_THEME=1' >> .profile

To try it out immediately, export the CALIBRE_USE_SYSTEM_THEME var and launch Calibre with:

export CALIBRE_USE_SYSTEM_THEME=1
calibre&

If you want it to work through d-menu (SUPER + D) logout and login backinto session.

That’s it!
