Debian – KDE keyboard repeat delay/rate settings don’t work/have no effect

debiankdekeyboardplasma5x11

How can I get the KDE (Plasma 5.8.6 on Debian Stretch) System Settings for keyboard repeat & delay to actually do something?

These settings:

Whenever I change and apply the settings I don't see any effect on the X11 repeat/delay state (as seen via xset q | grep "auto repeat delay").

Best Answer

In the Startup and Shutdown → Background Services configuration applet, make sure the Keyboard Daemon service ("Enables switching keyboard layout through shortcuts or system tray") is checked and in the "Running" state:

If this does not seem to have an effect, log out and back in. The settings should be applied afterwards.

For whatever reason this service is also responsible for propagating rate/delay changes to X11, which you can see live via:

watch -n1 'xset q | grep "auto repeat delay"'
