A window opened with a filled in crash report. The process was plasma-desktop and the failure was number 11.
The Black screen appeared. All that was working at first sight was the mouse.
By pressing ALT+F2 I got the run program prompt at the very top of the screen, I typed "konsole" to open one, and then typed plasma-desktop.
After a second or two, everything came back to normality, for at least 1 more second, then it crashed again.
This was the output of "plasma-desktop" when run from the 'konsole'.

Well, I figured out that it had to be something related to sockets as the 4 last lines say so.
By moving all the files from ~/.kde/socket-MYHOST/ to whatever folder I created just to rollback changes if nothing happened and running back plasma-desktop all came back to normality.
Well, that's all. I don't know if this solution will last long, Ill keep you inform
:)
GOOD BYE !
