Installed a bunch of updates to my Ubuntu 17.10 desktop tonight, and rebooted. Now the media keys at the top of my DELL USB keyboard no longer work.
When I run sudo showkey
it looks like the volume knob, play, stop, calculator, etc..., are still sending key down and key up events. But those don't seem to do anything anymore, as if Ubuntu is ignoring all the extra keys. Anyone have ideas?
