Thanks to Jarod Wilson, Beryl project can now be installed very easily on a Fedora Core 6 machine, via Fedora Extras repository. So, now that NVidia video driver supported by Beryl is no longer in BETA state, we also find Beryl for Fedora Core as being only one command away. You can install it with yum or pirut. The easiest way is to install a meta- package which will install all other needed files through dependencies.

WARNING: Some of you that had Beryl installed from third party repositories or packages need to delete the hidden folders and configuration files that Beryl created in your home directory (~/.beryl and ~/.emerald folders, and the ~/.beryl-managerrc file) and uninstall Beryl from your system before you install it from Fedora Extras.

So, if you run KDE as your default desktop environment, run the following command:

yum install beryl-kde

Or, if you have GNOME as your default window manager, please run the following command:

yum install beryl-gnome

After the installation process, you can start Beryl with the beryl-manager command. KDE users can add beryl-manager command to autorun, so it can start every time you log-in, with the following command:

ln -s /usr/bin/beryl-manager /root/.kde/Autostart/

The latest version of Beryl brings new things on the table, like Aquamarine for KDE users (an alternative Window Decorator that will use the regular window themes from the KDE control center) and Heliodor, same as Aquamarine, only that it's for GNOME users. It also brings new effects like Beam and Burn.

About Beryl:

Beryl is a fork of Compiz, which provides an open source desktop experience to the community that reflects the wishes of the users. Beryl is a combined window manager and composite manager written in C using OpenGL to provide acceleration. It is designed to be highly flexible, extensible, and portable.

Beryl is not dependent on any single xserver architecture, running on top of Xgl, AIGLX, and the nvidia binary drivers.

You can also download the Beryl source files now from Softpedia.
