Well, I'm glad nothing was broken, stolen or spirited away to regions 
unknown.

Rule of thumb regarding the various distros of Linux.  Never assume 
that they are set the same or use the exact same anything.  Go through 
a thorough review of every default setting when you first login to 
whatever desktop available after the installation has been completed.  
This should be done by the System Admin just as a double check insuring 
everything for the user is locked and preset according to whatever the 
policy is at the site.  The Sys. Admin should also recall that control 
apps in KDE are different in appearance, and sometimes in function in 
other desktop environments and sometimes accessed and invoked 
completely differently as well.

It is almost always a losing battle to discuss anything technical short 
of discrete mathematics in common English or any other human language.  
Face to face communication is difficult sometimes, describing technical 
events or items can be extremely trying.  From your more detailed 
description this time around it appears that your system didn't 
shutdown; it was merely asleep.  Completely different scenario than 
what was described.  Easier to resolve; still not a good thing in a 
24/7 always up data center environment, but reasonably acceptable in a 
college work lab or college library area.

As usual what is useful or not, critical or not, is completely relative 
to what your computer center is doing.  Supporting the company or city 
payroll center is completely different than a computer network 
functioning within a student lab facility.

Sometimes we are all a bit befuddled and bewildered stumbling about and 
by some circumstance manage to find a wall or chair to support 
ourselves just before we fall.  We shouldn't be surprised that 
sometimes working through Linux can be a little bit like our other 
experiences and we wonder haven't I gone through this before?  
Sometimes a bit of Linux is very similar to (sometimes) seeing Sarte's 
No Way Out or reading Nietzche's All Too Human.  In the meantime, a bit 
of wine, smooths anxiety a long way.

Glad you solved the puzzle and resolved it for yourself.  Bacchus is a 
wonderful god of inspiration, no?
