(To control your Debian KDE system)

Continuing the third part, this article discusses about further managing and controlling your Debian system through the KDE System Settings. In brief, you will see how to manage users, panel, kill process, change language, switch keyboard layout (with Korean Hangul as example), and create custom shortcut keys (Ctrl+Super+F to open Firefox browser as example). Happy learning!

1. Manage Users

You can create and delete new user account easily. You can change your password and avatar here.

The result can be seen on your start menu and on the session screen.

2. Manage Panel and User Interface

On Debian KDE, you may have more than one panel in any position, and you can add widgets on the desktop area.

 (Four acts: in clockwise order: (1) new panel on top (2) settings of bottom panel (3) widgets in form of clock, CPU monitor, calendar, and photo slideshow (4) widget selection panel)

3. Manage Running Processes

Use KSysGuard to see system load and running processes behind the scene. You find it on the start menu Applications > System > System Monitor.

On the first run, KSysGuard looks like below. It shows processes being run on your Debian KDE system. Most of these processes are invisible as they run in background. You can sort them out by Name, CPU%, and Memory Load.

(KSysGuard; left: process list, right: load graph)

You can "kill" a running process (get rid of it from your memory space) by clicking on it > End Process > the process "killed". 

(End process)

You can see the parent of the process by selecting 'All Processes, Tree' from the selection on top-right. For example, you can see below that 'firefox-esr' process is the parent of 'Web' process.

4. Switch User Interface Language

Debian GNU/Linux by default included more than 50 languages. If you don't speak English, you can switch the user interface to use your mother language instead. For example, you can switch to Indonesian, or Japanese, or, German, or Arabic, or anything else. 

To switch language, 
  • go to start menu > System Settings > Regional Settings > Language
  • you see the Preferred Languages box is empty, it's normal
  • choose your language from the Available Language (left) and click the '>' button to put it in the Preferred Languages (right)
  • OK and logout and login again
  • do it for any other language.

To switch the language back to English, simply remove your language from the Preferred Languages box and relogin.

(Language choices)

Here is a depiction of a Debian KDE system with 4 different languages namely Korean, Japanese, German, and Arabic. If you want to switch between the four of them, you simply logout and login after putting the language name into 'Preferred Languages' box. Easy.

 (Four different languages: clockwise order: Korean, Japanese, German, Arabic)
[Arabic script is right-to-left so the desktop arrangement above follows the script]

5. Switch Keyboard Layout

Following the user interface language, you may want to change the keyboard language. I will give you one example: Korean (Hangul), so you can type in Hangul script. How to enable Korean (Hangul) script keyboard?
  • go to start menu > Applications > Settings > IBus Preferences
  • go to Input Method tab > click Add > language selector dialog appears > search for Korean > select Korean > select Hangul > OK
  • you see Korean - Hangul option under English - US keyboard layout selection

(In clockwise order: (1) IBus Preferences, the foreign keyboard manager (2) List of enabled keyboard layouts including Korean (Hangul) (3) enabling Hangul mode from system tray (4) adding Korean (Hangul) into IBus)

6. Customize Shortcut Keys

Debian KDE can give you shortcut keys for (1) normal interaction (2) running program (3) executing command (4) desktop interaction. 

(The four different options: Custom, Global, Standard, and Web shortcuts)

How to make a custom shortcut? I show you an example to call Mozilla Firefox by pressing Ctrl+Super+S. Every time you press it, Firefox browser runs. To make it:
  • go to start menu > System Settings > Shortcuts > Custom shortcuts
  • click Edit > New > Global > Command
  • name it Firefox > go to Trigger Tab and set Ctrl+Super+F > go to Action tab and set firefox > Apply
  • test it.
