Abstract

A GUI is a complex piece of software; combined with the event driven capabilities, you may run into the situation where your GUI locks up on you. Unlike Windows, the Linux GUI isn't tightly bound into the underlying OS; instead, it's a set of separate programs running on top of the OS. As a result, however, you're not forced to restart your machine due to problems with the GUI itself. This whitepaper discusses the options you've got available to you to recover a failed X Windows session.
