Linux losing cool

A recurring "feature" of Linux is the unpredictability associated with it. Every reboot presents a new, usually unwelcome, challenge. Presently I am unable to launch any KDE application because I get an error that the DCOP could not be contacted. This system worked fine till yesterday, today DCOP is AWOL. Without DCOP I cannot launch any KDE window - no menus, no file manager. The solution is a reboot. But, I am not sure doing so will not bring up another problem.

While many lacunae in every distro can be attributed to the improper selection of preinstalled packages, the kind of problems like DCOP is more intrinsic. Expecting a user to spend a large part of the working hours trying to get the system workable is wishful thinking.
