In Windows, we have the Windows task manager which can be used when the system becomes stuck or any programs become stuck (ie, ctrl+shift+esc). We can close the hung programs using this. I'm not too familiar with Ubuntu, are there any alternatives in Ubuntu for this purpose?

xkill ... you can always open a terminal Ctrl+Alt+t and run xkill, then click on the window of the program that does not respond.

xkill must be installed beforehand, but is available in the official Ubuntu repositories.

Alternatively you can open the terminal, run top to determine the pid of the programm you want to close. Hit q to exit top, then run kill [pid]
