or perhaps it was not running, then: kstart5 plasmashell

Hmmm when I tried this restart of the plasmashell I got a lot of warning/error messages! Not knowing how to grok these, should I be worried that something is terribly wrong with this system?

Hi Patrick, thank you for responding, I will intersperse my replies within your responses so as to keep this organized.  Hmmm I am not sure what you are referring to here, but guessing here is the permissions for the sto relevant commands:

Any more ideas, I appreciate the thoughts given , thank you. Marc

first determine that plasmashell is actually running, ps aux |grep plasmashell

if not, you can start it: kstart5 plasmashell

ps: your sig is trash and has worthless, uninforcable legal ramifications. junk!

My sig is mostly meant to be humorous, there is no legal notifications within it. There is some Morse code for fellow amateur (ham) radio operators to have fun decoding, and some explanation of the attached digital signature key. Sorry if you found it confusing and not obvious! Thanks again so much for helping me try to solve these system slowdowns I am experiencing. One more  item of note, trying to use x11vnc service on the machine that is experiencing a slowdown, and then connecting in to it remotely from another machine using vncviewer is next to impossible! Then the response times become excruciatingly slow, up to 5 minutes or more and sometimes it just crashes the remote system..   Marc.... -- *"The Truth is out there" - Spooky* -- *_   _   .   .   .       .   .   .   _ _       .   _   _   _   _   .       .   .   .           _   .   .       .           .   _   _       .   _       _ _   .   .   .       .   _   _   .       _   .   .   _   .   _   _           _   _       .   _       .   _   .     _   .   _   . * Computers: the final frontier.

you can kill is manually by: kill 23370 then start it: kstart5 plasmashell

or if that fails: plasmashell but I do not know the ramifications of starting plasmashell that way.
