I just installed a new kbd/mouse combo with only one common dongle.
Exploring the row of extra keys above the Fkeys, I found the audio mute/volup/voldown worked but the one with a power off/on symbol crashed kded, and now that whole row of buttons is dead. And can't be restarted. But I was able to kill it with a root session of htop, and then I was able to restart it, and I think everthing is back to normal. Running as me, not root.
But I've no idea if its running as designed. Can this be looked at?
