You can force kill or quit an application by pressing alt+F2. press alt and hold it while pressing F2, now enter in dialog "xkill". this will run the program xkill. you mouse cursor will change into a death's head. now go to the window of the application which is not responding to kill it.

You should try Force Quit applet, you can also try this If you want to force a restart of your GUI, you can press CTRL+ALT+BACKSPACE - it then forces the X to restart, and not a total restart. To add Force Quit applet, just right click on your panel and click on add to panel , look under desktop and windows and there should be a force quit applet.

Try this terminal Code:

ps aux | grep <program-name>

This will give you pid # for the program.
after this type this code in terminal:

Code:

kill -9 <pid # to kill>
