by typingsu -c 'yum install gconf-editor'
- Next, run the command
gconf-editor
- In the navigation toolbar on the left, follow apps→metacity→general, and enable the compositing_manager checkbox.
Expected Results

- With metacity's compositing enabled, window shadows and ALT-TAB with window screenshots should be displayed correctly.
