Installed Xorg 7.2 using the instructions in this post: http://ubuntuforums.org/showthread.php?s=56e65f7d6efd667a8143b4348f0265ed&t=373087
Xorg 7.1.1 normally uses no more than 100 MB on my system (2 GB RAM). Memory usage for Xorg 7.2 jumped up to 500 MB within one day. Downgraded to Xorg 7.1.1 and memory usage has returned to less than 100 MB even after several days of usage.
