I was EXTREMELY disappoint to find that when I installed Parallels Tools 4.0.3540 that it removes all /etc/X11/xorg.conf.* files and does NOT back them up anywhere. I had several configs that I switched between for native boot, and parallels setups from the same physical drive. It took several hours to configure them all correctly to have them wiped w/o comment was beyond annoying. -- Shawn
