[img_assist|nid=161|title=|desc=|link=url,http://|align=left|width=100|height=100]Beryl is now in Gentoo's official ebuild repository, portage. There are instructions on installing it for Gentoo as well as how to set up your nvidia graphics card if you have one. The beautiful thing about having a nVidia graphics card is that with the latest nVidia drivers (build 9625) you no longer need to install XGL. You just add the
AddARGBGLXVisuals to your xorg.conf file and install the Beryl window manager and you get snazzy effects right out of the box. The other great thing is that you don't need to edit any other files on your computer. Just launch KDE for example, as usual, then run "beryl-manager" from a konsole window. You can change your window manager to beryl from the taskbar icon that shows up, restart beryl if it crashes, or switch back to kwin. You can also use emerald (the window-decorator) and change your emerald theme from the taskbar icon.
What is Beryl for? Well a lot of it is just eye-candy, like the spinning cube desktop for example. But some of it is really useful. In my opinion the most useful feature is the thing that imitates the Mac OS X Expose feature, that shows every window on your desktop and allows you to switch to the one you click on. You can invoke it with the F9 or F8 keys. The reveal desktop feature is pretty nice as well (activated with the F6 key).
