Hello forum,

I have an openSUSE 12.3 KDE 64bit installed on my laptop, which doesn't have indicator of caps lock key state.

I'm trying config desktop->Application and System Notification->Application tab->Event source: Accessibility-> A lock key has been activated->play a sound.

But this notification system doesn't capture the event of pressing any lock key/modifier key when I press them. "play sound", "pop up a notification" neither works. The event is just not detected. While these keys themselves all work well.

Where should I look at please?

Can you check to see if "kaccess" is running on your computer? It is a background process, and as such will only be visible in System Activity or KSysguard.

Maybe this helps:
