Can you please install "evtest", run "sudo evtest" in a terminal, choose the right device ("Dell extra keys", or just the standard keyboard), press these two keys, and copy&paste the output? Use Control-C to stop. Please also run "udevadm info --export-db > /tmp/udev.txt" and attach /tmp/udev.txt here. Thanks!
