How to fix mouse problems in KDE for newbies

Not long ago I have returned to Kubuntu, an official Ubuntu flavor that stands out for its beauty but also for its great differences from Unity or Gnome. For me these differences in many cases make me quit Kubuntu and opt for Xubuntu or Ubuntu with Unity.

One of the things that bothers me the most and that novice users will find even annoying is the fact that an application is executed with a mouse click or order while on other sites, you have to double click with the mouse. This is annoying if we really come from another operating system in which the double click works.

If you are new to Plasma or KDE you will face this problem and surely you want to change it or simply abandon the desktop or the official flavor. But don't worry then it's easy to change and also go back to single click if you want to adapt to the new format.

You have to configure the mouse so that the double click appears in Kubuntu

However, the place where it is done is not as intuitive as many of us may think. To make the change, first we have to go to the KDE Menu and go to Preferences -> System Preferences. A window like the following appears:

In this window we go to Input devices, where really is the mouse settings and in the mouse section we look at the icons section. There we have to mark the option «a double click opens file ...» Then we click Apply and close the rest of the windows.

Now every time open an application or a file we will need to double click with the mouse to open it as in the rest of the operating systems. Also, this tutorial is valid for the latest versions of KDE and Plasma, so it doesn't matter if you have the latest version of Kubuntu or Linux Mint KDE, the result will be the same.
