I realized that this option is honored by kmod=E2=80=99s =E2=80=98modprobe= =E2=80=99 command, which we use, but not by our initrd code, and (gnu system linux-initrd) has =E2=80=9Cusbkbd=E2=80=9D among the modules that it always loads. Commit 7ba903b changes our code to honor =E2=80=98modprobe.blacklist=E2=80= =99 as well. Jessica: To test what Ricardo suggests, you would have to somehow login to your laptop (over SSH or using a different keyboard) and do: sudo guix pull ;; Edit configuration.scm to add =E2=80=98kernel-arguments=E2=80=99 to th= e config: ;; (operating-system ;; =E2=80=A6 ;; (kernel-arguments '("modprobe.blacklist=3Dusbkbd"))) sudo guix system reconfigure /path/to/configuration.scm HTH!
