Solution
Please Install the Updated Packages.
Insight
The x11 server would crash when setting a pixmap for the root window and later trying to restore the defaults. This update has been patched to correct the problem.
Update:
An error in packaging caused an incorrect conflict with the updated x11-server packages and the compiz package. New packages are available that resolve this conflict, and we apologize for any inconvenience this may have caused.
