My HP laptop keyboard randomly gets stuck repeating a key when I type too fast. I then plug in and use a USB keyboard (which stops the key repeating), but the laptop's keyboard stays dead. Everything else works as usual, even the softkeys. Is there a kernel, X, or KDE way to restart the keyboard without rebooting?
The machine is in such a situation now. Here some output that may help:

That's weird. I'd say it's a hardware issue, but I can't explain how plugging new keyboard stops repetition.
Does anything appear in dmesg when this happens?
Anyway, try
rmmod atkbd ; modprobe atkbd reset=1Offline
Thank you, mich41! That worked and I am thrilled! Rebooting was a major productivity killer.

It is weird indeed. And very random. I can go weeks without an issue and then have several in one day.
I suppose when a key is pressed after the USB keyboard is plugged in causes the other to stop. Both keyboards can be active at the same time normally.
Nothing appears in dmesg.
Thanks again.
