I am using Zim desktop wiki for note taking on Ubuntu. I was trying to set up a dark theme for Zim. I couldn't get any information on it on the internet.

There is a Windows-specific page available on the internet which talks about setting up a dark theme, but there's no solution for Linux systems.

Is it possible to get a similar dark theme set up on Zim wiki on Ubuntu 18.04.1?


I use Zim quite a bit, but there are a few other apps that caused me to change all my GTK apps to a dark theme, using the Gnome Tweaks application.

To try this method, first install the Gnome Tweaks tool:

sudo apt install gnome-tweak-tool

Then, hit the Super key or click the "Show Applications" button on the bottom left of the desktop, and type "tweaks".

After tweaks comes up, select the "Appearance" tab. You'll notice that the first section is "themes". For Zim, the "Applications" setting is the one controlling the theme.

On 18.10, I was able to select Adwaita-dark, and Zim picked up the settings immediately.

There's a relevant makeuseof.com article with a lot more information on how to change the gtk theme, if you need it.

This is a quick and easy change, so you can change back if the aesthetic doesn't please you.

  • Perfect. That's exactly what I was looking for. Thanks a lot @belacqua. – Shihab Khan Dec 9 '18 at 6:38

    @ShihabKhan That's great. As I'm OK with a universal dark theme, I haven't tried application-specific methods, like those mentioned here (which are more fiddly but still workable): unix.stackexchange.com/questions/14129/… – belacqua Dec 12 '18 at 0:00
