How can I map Win + L to lock screen in KDE4?

Question

How can I map the keyboard shortcut to locking a session in KDE 4?

Answer 1

Here's what you could do to remap session locking from default Ctrl+Alt+L (tested with KDE4.3) :

1. Go to "System Settings" (KDE menu).
2. Choose "Keyboard & mouse" (on "General" tab).
3. Choose "Global Keyboard Shortcuts" on the left.
4. Choose "Run Command Interface" from "KDE component" dropdown list.
5. Choose "Lock session".
6. Select "Custom".
7. Click on "None" (button changes to "Input...").
8. Compose your desired sequence by pressing appropriate buttons on your keyboard.
9. Click "Apply".

• KDE Component: The KDE Session Manager (at the bottom of the list, scroll down)
• Lock Session

Answer 6

default Ctrl+Alt+l did not work for me, maybe overshadowed by some other app - I had to explicitly set the shortcut as mentioned in the selected answer.

Also beware not to select "kscreenlocker", but the KDE session manager. Win/Meta+L worked fine here.

Answer 7

I imagine that man xmodmap will help with the keybinding part of it.

I don't know enough of KDE to help with what keysequence already locks the screen.

Answer 8

In Debian 10 KDE Plasma it's:

• System Settings (from menu)
