Manual Installation

To build the theme the follwing packages are required

  • autoconf
  • automake
  • pkg-config or pkgconfig for Fedora
  • libgtk-3-dev for Debian based distros or gtk3-devel for RPM based distros
  • git to clone the source directory

Note: For distributions which don't ship separate development packages, just the GTK 3 package is needed instead of the -dev packages.

For the theme to function properly, install the following

  • GNOME Shell 3.14 - 3.24, GTK 3.14 - 3.22
  • The gnome-themes-standard package
  • The murrine engine. This has different names depending on the distro.
    • gtk-engine-murrine (Arch Linux)
    • gtk2-engines-murrine (Debian, Ubuntu, elementary OS)
    • gtk-murrine-engine (Fedora)
    • gtk2-engine-murrine (openSUSE)
    • gtk-engines-murrine (Gentoo)

Install the theme with the following commands

1. Get the source

Clone the git repository with

git clone --depth 1 && cd arc-theme

2. Build and install the theme

./ --prefix=/usr
sudo make install

Other options to pass to are

--disable-transparency     disable transparency in the GTK3 theme
--disable-light            disable Arc Light support
--disable-darker           disable Arc Darker support
--disable-dark             disable Arc Dark support
--disable-cinnamon         disable Cinnamon support
--disable-gnome-shell      disable GNOME Shell support
--disable-gtk2             disable GTK2 support
--disable-gtk3             disable GTK3 support
--disable-metacity         disable Metacity support
--disable-unity            disable Unity support
--disable-xfwm             disable XFWM support

--with-gnome=<version>     build the theme for a specific GNOME version (3.14, 3.16, 3.18, 3.20, 3.22)
                           Note 1: Normally the correct version is detected automatically and this
                           option should not be needed.
                           Note 2: For GNOME 3.24, use --with-gnome-version=3.22
                           (this works for now, the build system will be improved in the future)

After the installation is complete the theme can be activated with gnome-tweak-tool or a similar program by selecting Arc, Arc-Darker or Arc-Dark as Window/GTK+ theme and Arc or Arc-Dark as GNOME Shell/Cinnamon theme.

If the --disable-transparency option was used, the theme will be installed as Arc-solid, Arc-Darker-solid and Arc-Dark-solid.



sudo make uninstall

from the cloned git repository, or

sudo rm -rf /usr/share/themes/{Arc,Arc-Darker,Arc-Dark}

Chrome/Chromium theme

To install the Chrome/Chromium theme go to the extra/Chrome folder and drag and drop the arc-theme.crx or arc-dark-theme.crx file into the Chrome/Chromium window. The source of the Chrome themes is located in the source Chrome/arc-theme folder.

Plank theme

To install the Plank theme, copy the extra/Arc-Plank folder to ~/.local/share/plank/themes or to /usr/share/plank/themes for system-wide use. Now open the Plank preferences window by executing plank --preferences from a terminal and select Arc-Plank as the theme.

Arc-Dark for Ubuntu Software Center

The Arc Dark theme for the Ubuntu Software Center by mervick can be installed from here. It solves readability issues with Arc Dark and the Ubuntu Software Center.


If you use Ubuntu with a newer GTK/GNOME version than the one included by default (i.e Ubuntu 14.04 with GTK 3.14 or Ubuntu 15.04 with GTK 3.16, etc.) the prebuilt packages won't work properly and the theme has to be installed manually as described above. This is also true for other distros with a different GTK/GNOME version than the one included by default


If you get artifacts like black or invisible backgrounds under Unity, disable overlay scrollbars with

gsettings set com.canonical.desktop.interface scrollbar-mode normal


If you find a bug, please report it at


Arc is available under the terms of the GPL-3.0. See COPYING for details.
