I've just installed Xfce on my Ubuntu system. I used Gnome + Beryl before, but it monopolized the OpenGL interface (the Beryl effects ran really smooth, but when I launched another OpenGL app like Armagetron, I got like 2 fps).
I wanted to get more eye candy (a compositing windows manager, actually) while running a system that does not monopolize the OpenGL interface. Also, the Beryl manager caused some funny bugs on some soft (Eagle CAD, notably): the text became transparent (difficult to use).
So I've installed Xfce, and uninstalled Beryl.
Now Eagle works, all OpenGL apps run perfectly, but I don't get any eye candy on Xfce - windows are solid, no shadows. Also, I can only select A resolution of 1280x1024, 1024x768 or "Default" (which amounts to 1600x1200x32, I configured it on Gnome).
How do I configure it/activate the transparency?
Thanks a lot!
