Guix,
Some (=none) of you might remember my X keyboard woes on #guix,
where I was stuck without a backspace key or the key below it (\,
|) on my ThinkPad X230T's US keyboard. Both sent out
‘XF86ScreenSaver’ codes instead.
I tried dozens of things, both in my system configuration and by
running random stateful xkb commands (naughty), and managed to
‘fix’ the bug without ever finding the cause (very naughty).
I think I was looking for it in all the wrong places. Something
goes wrong before the kernel even boots. Here's my
keyboard-layout:
(keyboard-layout
(keyboard-layout
"us" "dvp" ;
kaufmann.no/roland/dvorak
#:model "thinkpad" ; pc104, pc105, thinkpad,
…
#:options ; list of XKB Option
strings
(list "" ; unset all inherited
options
"caps:shiftlock" ; Shift Lock affects all
keys
"shift:breaks_caps" ; Shift cancels Caps Lock
"compose:102" ; next to left Shift on
pc105
"lv3:ralt_switch" ; key to choose 3rd level
"nbsp:level3n" ; nbsp @lv3, thin nbsp
@lv4
"numpad:shift3" ; Num Lock: Shift chooses
lv3
"kpdl:semi" ; key pad semicolon @lv3
"misc:typo" ; add extra typographic
chars
"ctrl:swapcaps" ; onwards for great Emacs
"terminate:ctrl_alt_bksp"))) ; zap X just to watch it
die
Here's what works just fine:
(service slim-service-type
(slim-configuration
(xorg-configuration
(xorg-configuration
(keyboard-layout keyboard-layout)
…
However, today I tried to (re-)add it to GRUB, too, and ended up
writing the following comment:
(bootloader
(bootloader-configuration
(bootloader grub-efi-bootloader)
;; XXX Strange bug: GRUB can read the LUKS passphrase, but
afterwards (at
;; the menu screen) no longer responds to key presses. Even
stranger: it
;; makes my X230T's backspace key send ‘XF86ScreenSaver’s even
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
actual work-workstation (which is also my funstation) while
entering my passphrase 5 times, every time, makes that an
unpleasant and tedious affair.
Kind regards,
T G-R
