In your environment, you need to type :
/opt/shashlik/bin/shashlik-run com.tdo.showbox showbox.

You should also install libgl.so. It depends what distro you're running: on Debian do this by sudo apt install libgl1-mesa-dev. The exact package and install command will vary depending on your distribution.

try
sudo apt-get install kde-baseapps-bin
if you still have black screen switch to Intel Graphics or simply logout and re log in

@panospetridisoglou Thanks for your ideas.
In fact I have install the newest version of kde-baseapps-bin already.
I tried to restart and relogin system as well, but just still got a black screen.
However, I havn't another Graphics Card that is not Intel, so I cannot test this point this moment.
