Manual Uninstallation

Delete the installed directories:

sudo rm -rf /usr/share/themes/Materia{,-compact,-dark,-dark-compact,-light,-light-compact}



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

Chrome Theme

To use the Chrome theme;

  1. Open the chrome folder on /usr/share/themes/Materia<-variant>.
  2. Drag and drop the .crx files into the Chrome/Chromium Extensions page (chrome://extensions).

GDM Theme

You can change the GDM (lock/login screen) theme by replacing the default GNOME Shell theme.
See the wiki for details: https://github.com/nana-4/materia-theme/wiki/GDM-Theme


Materia allows you to change the color scheme relatively easily. See HACKING.md for details.
