Manual Installation

To build the theme the following packages are required

  • autoconf
  • automake
  • sassc for GTK 3, Cinnamon, or GNOME Shell
  • pkg-config or pkgconfig for Fedora
  • git to clone the source directory
  • optipng for GTK 2, GTK 3, or XFWM

The following packages are optionally required

  • gnome-shellfor auto-detecting the GNOME Shell version
  • libgtk-3-dev for Debian based distros or gtk3-devel for RPM based distros, for auto-detecting the GTK3 version

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 3.18 - 3.32, GTK 3.18 - 3.24
  • The gnome-themes-extra 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)

Arc icon theme

The Arc icon theme is available at


A port of Arc for the Plasma 5 desktop with a few additions and extras. Available here.

Plank theme

As of version 20180201 the plank theme will be installed along with the normal Arc-Flatabulous gtk theme. You can disable the install by passing disable-plank to the autogen command. Now open the Plank preferences window by executing plank --preferences from a terminal and select Gtk+ 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


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