SUMMARY

Everything is going nice, your desktop and applications keep running smoothly while you're editing a "LibreOffice Draw" document when you suddenly realize that you no longer have panels and your desktop background is now a black hole, not letting any information out! However "kwin" and the usual keyboard shortcuts are still there! 

So I call "yakuake". Here is what I get as output of command `ps axu | grep plasma`:

   `6535 ? S 0:00 file.so [kdeinit5] file local:/run/user/1000/klauncherTJ1322.1.slave-socket local:/run/user/1000/plasmashellHf6516.2.slave-socket` 

Next I `kill -9 6535` to pass the whole process and restart "plasma" using `plasmashell -n` with poor results. Happiness lasts a second...

Now the "Crashing Reporting Assitant" comming out into our aid and the rest of history is already known... Their «hair and signals» are bellow

greetings!
