Installation

Manual installation

You can install the icon theme by copying the arcticons-light and/or arcticons-dark folder into ~/.local/share/icons for a user-wide installation or into /usr/share/icons for a system-wide installation.

Applying the icon theme

In GNOME Shell, you can either use the Terminal and type the command gsettings set org.gnome.desktop.interface icon-theme <arcticons-light/arcticons-dark> or use the GNOME Tweaks GUI to change the icon theme to Arcticons Light or Dark. (To change the icons for Qt/KDE applications in GNOME as well, you need to open qt5ct and/or qt6ct and select the icon theme there)

In KDE, you can select the icon theme in the System Settings > Icons.
