&gt; And just yesterday my Linux did what I&#x27;ve never seen an OS do before - it losts it UI clock display. The solution was simple and typical for Linux - it involved killing a random process.<p>What desktop environment was that?  There are many different ones available for Linux systems, and they don&#x27;t all behave that way.  e.g. I&#x27;ve never had that kind of problem with KDE3&#x2F;TDE or KDE4.
