On FC6, KDE, with the Radeon driver for my 256MB X1400 video card. When clicking on the Beryl icon, one is presented with the choice of window managers: Beryl, Metacity, or Kwin. I cannot select Beryl. When I do, the screen flickers as if it's starting, but then I get either Metacity or Kwin, whichever is set as the default. I do not know where to begin troubleshooting, and googling the problem has not found any other similar incidents. Where should I begin? Thanks.
