Manual Installation

  1. Download and extract the stable archive.

    cd /tmp
    curl -sL https://github.com/nana-4/Flat-Plat/archive/v20161227.tar.gz | tar xz
  2. In terminal, move to the extracted directory and run ./install.sh as root.

    cd Flat-Plat-20161227 && sudo ./install.sh
  3. Select the theme via gnome-tweak-tool or other suitable tools.

  4. Optionally, configure the following settings:

    • Set the system font size to 9.75 (= 13px at 96dpi) or 10.5 (= 14px at 96dpi).
    • Open the chrome folder on /usr/share/themes/Flat-Plat*/ and drag and drop the .crx files onto the Chrome/Chromium extensions page (chrome://extensions).

Note: Series 3.14 and 3.16 are no longer supported. If you want to get the final version, you can download from the link below.

Manual Uninstallation

  • Delete the installed directories.

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

GDM (Lock/Login Screen)

You can change the GDM theme by replacing the default GNOME Shell theme.
But please be careful because if it fails, the desktop environment may not operate correctly.

⚠️ Cautions:

  • When applying this, other third-party GNOME Shell themes would look broken.
  • If GNOME Shell has been updated, you will need to install this again.


  1. Back up and replace the existing .gresource file after selecting the GTK+ theme.

    GTK_THEME=$(gsettings get org.gnome.desktop.interface gtk-theme | sed "s/'//g")
    sudo cp -iv --backup /usr/share{/themes/$GTK_THEME,}/gnome-shell/gnome-shell-theme.gresource

    Developer note:
    If you don't want to overwrite the backup on the second and subsequent runs, delete the --backup option.

  2. Restart GNOME Shell (press Alt + F2, then type r).


  1. Restore to original theme from the backup.

    sudo mv -iv /usr/share/gnome-shell/gnome-shell-theme.gresource{~,}
  2. Restart GNOME Shell (press Alt + F2, then type r).
