ADDITIONAL INFORMATION

The only work around I have found is to unplug the keyboard and then type on the laptop keyboard itself. I seem to recall typing on the laptop keyboard didn't work (nothing showing up) while the USB keyboard was plugged in.

Did you reverse the observed and expected sections?

Comment 3 Nate Graham 2024-03-01 22:19:25 UTC

And do the keyboards differ in their physical layouts?

Actually I am not sure how to fix. The Bugzilla UI doesn't make it obvious.

I believe so, yes. One is a Das Keyboard and the other is a Logi.

What a funny thing to do. :) Still, it seems like we can handle this by re-evaluating the keyboard layout on wake-up.
