Bit of Drama. Said Yes to 'nac' utility.
I Reset my Desktop as it was, too easy.
Then decided I'd "Hide the Cashew" (togglecashew)which is a rectangular ITEM, called, 'GO' now
as seen in PIC.
"togglecashew" blanked the screen - Ctrl+Alt+Backspace - Logged me out.Logging in the 'Splash Screen' froze.
Ctrl+Alt+Backspace, got me to Login GUI from where I Re-Booted.
Was able to Login, seems stable.
Not a lotta fun, but the excess "New Activity" Globes are gone, ... well actually a right click on the Destop > Activities; shows me the two 'Globes' I renamed are present.
I must remember the second Activity doesn't have a Desktop,
which is all a bit Halloweeny, (black) however once the bugs have been swept this seems a workable method: "togglecashew", and 'clean_nac' .
Too tired to Grok the depths of reading which created the scripts, which I advise myself should be undertaken so I know what is going on, but that I'll do on the morrow.
Hope you enjoyed the Pic's
