How to force close a app in Ubuntu?

I am using Ubuntu, and one of the apps has stopped responding (it hanged). I tried closing it, but nothing was happening. I can press Ctrl + Alt + Del in Windows and use Task Manager to close an app. Is there something similar in Ubuntu? How can I force close or kill the process of the app that is not responding?

It’s not exactly like Ctrl + Alt + Del in Windows, but you can use xkill to force close an app quickly. Here’s how:

  • Press Alt + F2 to open the “Run” dialog.
  • Type xkill and press Enter.
  • Your mouse pointer will turn into an “x”.
  • Now, click on the app that is not responding, and it will be closed instantly.

This method is faster than opening the System Monitor. If you change your mind and don’t want to close anything, you can right-click to cancel xkill.
