KDE configuration (old, migrateafter)

  • K Menu -> Computer -> System Settings -> Common Appearance and Behavior -> Shortcuts and Gestures -> Global Keyboard Shortcuts -> KDE component = kwin -> Search = quick

    Here choose
    • Win+Left for "Quick Tile Window to the Left" Action.
    • Win+Right for "Quick Tile Window to the Right" Action.

Digital Clock

Display the date in YYYY-MM-DD format in the panel's clock application

Panel -> Right click on the digital clock -> Digital Clock Settings -> Appearance -> Information -> Date Format -> Choose "Short date" from the drop down -> click the settings icon next to it -> Date & Time -> Short date format -> YYYY-MM-DD -> Apply -> ok -> ok


The idea here is to make iceweasel (a GTK+ application) have the same look and feel of other KDE applications.

sudo apt-get install kde-config-gtk-style qtcurve lxappearance
K Menu -> System Settings -> Application Appearance -> GTK -> Select a GTK2 Theme: -> QtCurve -> Apply

default browser

The default browser in KDE is Konqueror. Change it to iceweasel as follows.

K Menu -> System Settings -> File Associations -> Search for html in the Configure file associations panel -> text -> html -> Application Preference Order -> Move Iceweasel all the way to the top -> Apply


K Menu -> Search for "Virtual Desktops" -> Desktops ->

Numer of desktops = 4
Numer of rows = 2

Give names for each desktop as you see fit.

K Menu -> Search for "Virtual Desktops" -> Switching ->
Animation = "Desktop Cube Animation"

Get rid of debug output

konsole -> kdebugdialog -> Click the "Deselect All" button
                        -> Select Disable all debug output -> click OK

Add frequently used apps to panel

  • K menu -> search for konsole -> right click on the konsole icon -> add to panel

repeat the same excercise for iceweasel.

Startup scripts

All the scripts in ~/.kde/Autostart will be executed whenever a user logs into a new KDE session.
Here is a sample script:

    % cat reading.zsh 
    #! /usr/bin/env zsh
    acroread /a page=40 "/home/rajulocal/books/currently_reading/file1.pdf" &
    sleep 2
    acroread /a page=1  "/home/rajulocal/books/currently_reading/file2.pdf" &
    iceweasel &

Make it executable

    % chmod +x reading.sh
