Beryl project is still on its heavy development phase and the application is not quite stable.

After the installation, I found that Shift+Backspace just restart the X server. It’s quite often that I press the Shift key when typing uppercase letters but still holding it when I want to delete something. So my works not saved all were gone

Another issue is that the nvidia driver can’t enable direct rendering when running XGL. The glxgears can’t run smoothly.

On another machine, when click on the System -> Quit menu item, the X server hangs and the computer must be restarted.

So now I have it disabled and may enable it when it is suitable for incorporation in a X.Org distribution. Eye candy things may be not mouth candy.
