How to Enable Dark Theme on ElementaryOS

Instructions for enabling dark theme (almost) everywhere on ElementaryOS

Pantheon Apps

1. Replace the contents of /usr/share/dbus-1/interfaces/io.elementary.pantheon.AccountsService.xml with this file.
2. Replace the line <annotation name="org.freedesktop.Accounts.DefaultValue" value="0"/> with <annotation name="org.freedesktop.Accounts.DefaultValue" value="1"/> under PreferColorScheme section.

Qt Apps

1. Install Kvantum

   Kvantum can be used to style Qt apps. Papirus Team maintains a PPA containing recent versions of qt5-style-kvantum and qt5-style-kvantum-themes packages:

   add-apt-repository ppa:papirus/papirus
   apt install qt5-style-kvantum qt5-style-kvantum-themes
   

2. Set QT_STYLE_OVERRIDE variable to kvantum:

   echo "export QT_STYLE_OVERRIDE=kvantum" > /etc/profile.d/qt-style-override.sh
   

3. Restart your session, run Kvantum and choose a dark theme that matches the current ElementaryOS dark theme

   I personally like KvGnomeDark theme but for some reason, it doesn't have dark title bars! That can be fixed by creating a modified version of the theme using Kvantum Manager app:

   1. From Change/Delete theme section, select KvGnomeDark and click on Use this theme button
   2. In Configure Active Theme section, click the Save button. Doing so will create a config file in $HOME/.config/Kvantum/KvGnomeDark#/KvGnomeDark#.kvconfig
   3. Edit the abovementioned file and add the line dark_titlebar=true anywhere under the [%General] section
