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.

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:
(keyboard-layout
(keyboard-layout
"us" "dvp" ;=20
kaufmann.no/roland/dvorak
#:model "thinkpad" ; pc104, pc105, thinkpad,=20
=E2=80=A6
#:options ; list of XKB Option=20
strings
(list "" ; unset all inherited=20
options
"caps:shiftlock" ; Shift Lock affects all=20
keys
"shift:breaks_caps" ; Shift cancels Caps Lock
"compose:102" ; next to left Shift on=20
pc105
"lv3:ralt_switch" ; key to choose 3rd level
"nbsp:level3n" ; nbsp @lv3, thin nbsp=20
@lv4
"numpad:shift3" ; Num Lock: Shift chooses=20
lv3
"kpdl:semi" ; key pad semicolon @lv3
"misc:typo" ; add extra typographic=20
chars
"ctrl:swapcaps" ; onwards for great Emacs
"terminate:ctrl_alt_bksp"))) ; zap X just to watch it=20
die
Here's what works just fine:
(service slim-service-type
(slim-configuration
(xorg-configuration
(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
(bootloader-configuration
(bootloader grub-efi-bootloader)
;; XXX Strange bug: GRUB can read the LUKS passphrase, but=20
afterwards (at
;; the menu screen) no longer responds to key presses. Even=20
stranger: it
;; makes my X230T's backspace key send =E2=80=98XF86ScreenSaver=E2=80=99=
s even=20
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
actual work-workstation (which is also my funstation) while=20
entering my passphrase 5 times, every time, makes that an=20
unpleasant and tedious affair.
Kind regards,
T G-R
