Microsoft Windows and Apple Mac are two of the most widely used worldwide, but if you’re looking for a free and open source operating system that you can tinker around with it on your raspberry Pi for example then look no further than Linux. Linux Mint is the most popular Linux distro according to distrowatch.com (http://distrowatch.com/table.php?distribution=mint).
If you’re new to Linux and wondering about what is a Linux distro; think of a distro as a distinct flavor of Linux that has its own advantages and in some cases its uses. For example Android is a Linux distro that is optimized for touchable devices (Phones, tablets, TVs, Cars and now watches).
This post will present a step by step guide on how to terminate unresponsive programs in Linux Mint; it’s worth noting that Xkill (a tool used to terminating unresponsive programs ) is part of the utilities pre-installed in Linux Mint, and all what we’re going to do is to add a shortcut for it on the desktop.
Step One: First, go to Menu >> Applications >> Preferences >> Keyboard.
Step Two: A new window will pop-up, select the Keyboard shortcut tab from the top menu.
Step Three: In the new tab, click the “Add Custom Shortcut” tab to create a custom shortcut.
Step Four: A new window will pop-up; enter xkill in both the Name and Command fields then click on the Add button.
Step Five: Click on Unassigned at the xkill row in the Keyboard Shortcuts window.
Step Six: Press a new key combination, e.g. Ctrl+shift+F.
Now you’re ready to roll and Xkill is locked and loaded. Press the key combination you’ve selected in step six to turn the cursor to an X-sign, move the X-sign and drop it into a program interface to terminate the unresponsive program, or cancel the X-sign with a right-click.
