This test case tests whether accelerated OpenGL applications under compositing managers work with the Radeon video driver, with kernel mode setting enabled. You must be using a card supported by the Radeon video driver.


  1. Ensure the 'nomodeset' kernel parameter is not enabled in your bootloader configuration (unless you need it for basic X operation to suceed)
  2. Ensure the file /etc/X11/xorg.conf does not exist, or is a known-good configuration file that uses the 'radeon' driver
  3. Ensure that Package-x-generic-16.pngcompiz and related packages are installed by running the command: su -c "yum install compiz compiz-gnome desktop-effects"
  4. Ensure the Package-x-generic-16.pngglx-utils package is installed by running the command: su -c "yum install glx-utils"
  5. Shut your system down entirely, then start it up again

How to test

  1. Enable Compiz by selecting SystemPreferencesDesktop Effects. Then check Enable Desktop Effects, and check the Workspaces on a Cube and Windows Wobble when Moved boxes
  2. Run the command glxgears (or, optionally, any other OpenGL app you can think of)
  3. Try covering the glxgears window with other windows
  4. Move the glxgears window around
  5. Rotate the desktop cube (ctrl+alt+drag the mouse)

Expected Results

  1. OpenGL apps should run properly and with full acceleration and behave as any other window. Covering them should work properly, they should move smoothly and wobble (when this effect is enabled), and should render properly when the desktop cube is being rotated
