Guix,

Some (=3Dnone) of you might remember my X keyboard woes on #guix,=20
where I was stuck without a backspace key or the key below it (\,=20
|) on my ThinkPad X230T's US keyboard.  Both sent out=20
=E2=80=98XF86ScreenSaver=E2=80=99 codes instead.

I tried dozens of things, both in my system configuration and by=20
running random stateful xkb commands (naughty), and managed to=20
=E2=80=98fix=E2=80=99 the bug without ever finding the cause (very naughty).

I think I was looking for it in all the wrong places.  Something=20
goes wrong before the kernel even boots.  Here's my=20
keyboard-layout:

Here's what works just fine:

              (xorg-configuration
               (keyboard-layout keyboard-layout)
               =E2=80=A6

However, today I tried to (re-)add it to GRUB, too, and ended up=20
writing the following comment:

 (bootloader

   on Linux.
   ;; (keyboard-layout keyboard-layout)
   (target "/boot/efi")
   (timeout 1))))

This is 100% reproducible.

I'll try to narrow it down a bit, but the combination of losing my=20

unpleasant and tedious affair.

Kind regards,

Even in =E2=80=98guix system vm --full-boot=E2=80=99, right?

It could be that the XKB =E2=86=92 GRUB conversion fails.  You can see
conversion process in (gnu bootloader grub).  In that case, that would
be a =E2=80=98grub-mklayout=E2=80=99 or a =E2=80=98ckbcomp=E2=80=99 bug.

I=E2=80=99ve only tested this stuff with standard keyboard layouts with one=
 or
two options at most, so it may be that you=E2=80=99re pushing it to its lim=
its.

I=E2=80=99m surprised what GRUB does has an impact on what Linux does
afterwards, though.

Thanks,
Ludo=E2=80=99.
