Unsupported Apps and Desktops

  Because they are based on their own stylesheet that conflicts with GTK standards.

Installation

Distro Packages

NOTE: Distro packages could be outdated and incompatible with your desktop environment. You can check the latest version here.

Flatpak

flatpak remote-add --if-not-exists flathub https://dl.flathub.org/repo/flathub.flatpakrepo
flatpak install flathub org.gtk.Gtk3theme.Materia{,-dark,-light}{,-compact}

Manual Installation

See `INSTALL.md` for details.

Recommendations

Font

• Use a font family including Medium weight (e.g. Roboto or M+) to properly display the theme.
• Set the font size to 9.75 (= 13px at 96dpi) or 10.5 (= 14px at 96dpi).

Chrome Extensions

To improve the appearance of Chrome, you can install our Chrome extensions as follows:

1. Open the /usr/share/themes/Materia<-variant>/chrome folder in your file manager.
2. Drag and drop the .crx files into the Chrome's Extensions page (chrome://extensions).

GDM Theme

You can change the GDM (lock/login screen) theme by replacing the default GNOME Shell theme.
See `INSTALL_GDM_THEME.md` for details.

Customization

Materia can be customized with GUI application, **oomox theme designer**.

Materia also allows you to change the color scheme relatively easily in other ways. See `HACKING.md` for details.
