Description

This test case tests whether compositing_manger setting of metacity works successfully with the Radeon video driver, with kernel mode setting enabled. You must be using a card supported by the Radeon video driver.


How to test

  1. Ensure the 'nomodeset' kernel parameter is not enabled in your bootloader configuration (unless you need it for basic X operation to succeed)
  2. Ensure the file /etc/X11/xorg.conf does not exist, or is a known-good configuration file that uses the 'radeon' driver
  3. Shut your system down entirely, then start it up again
  4. Run gconf-editor
  5. Follow apps->metacity->general from navigation toolbar left, check 'compositing_manager' checkbox. See whether everything works fine.
Editing GConf key
Alternately, you can use the following command: 
gconftool-2 --set --type=bool /apps/metacity/general/compositing_manager true

Expected Results

  1. The graphical desktop should be displayed correctly when 'compositing_manager' is checked
  2. With metacity's compositing enabled, window shadows and ALT-TAB with window screenshots should be displayed correctly.
