Ubuntu Linux 6.06 LTS—the free operating system that eWEEK Labs recently named the current Linux desktop champ—recently hit a sizable pothole on the road to enterprise-class stability.
In a bug-fix update to the distribution's xserver-xorg-core component—the system application responsible for serving Ubuntu's graphical environment—the Ubuntu project team disabled the GUIs of many users upon their next reboot.
The Ubuntu project handled itself fairly well in the wake of this mishap: It promptly replaced the offending package in Ubuntu's network software repositories, posted notices about the bug and the fix prominently on its Web site and forums, and promised its community a full explanation pending further investigation.
