Today we're introducing you to a newly released GTK+ theme that features transparent and flat elements and is compatible with multiple desktop environments and Linux distributions. The theme is called Arc.
Before going into detail, we suggest that you take a quick look at the gallery attached below, so you have a basic idea of what the theme looks like. Also, you should be aware that it currently works with GTK+ 2.x, GTK+ 3.x, GNOME-Shell, Budgie, Unity, and Pantheon user interfaces, all of them using the GNOME Stack.
Also, the developer of the Arc theme informs us that it has been successfully tested on the Ubuntu 15.04 (Vivid Vervet), Arch Linux, elementary OS 0.3 Freya, Fedora 21, Fedora 22, Debian GNU/Linux 8.0 (Jessie), Debian Testing, Debian Unstable, OpenSuSE 13.2, openSUSE Tumbleweed, and Gentoo Linux operating systems.
Requirements and installation instructions
To build the Arc theme, you will need to first install some packages, such as autoconf, automake, pkg-config (pkgconfig for Fedora), libgtk-3-dev for Debian/Ubuntu-based distros or gtk3-devel for RPM-based ones, git, gtk2-engines-pixbuf, and gtk-engine-murrine (gtk-murrine-engine for Fedora).
The Arc theme does not yet have binary packages, so you will need to grab the latest source code from the project's Git repository and compile it. Therefore, open a Terminal app and run the following commands, one by one, hitting the Enter key after each one and waiting for the previous command to finish before adding the next.
git fetch --tags
git checkout $(git describe --tags `git rev-list --tags --max-count=1`)
./autogen.sh --prefix=/usr
sudo make install
Update: We've updated the article on June 8, 2015 to inform our users that binary packages for the Debian, Fedora, openSUSE, and Ubuntu Linux distributions are now available at http://software.opensuse.org/download.html?project=home%3AHorst3180&package=arc-theme with detailed installation instructions.
