[SOLVED] keyboard inoperable after kernel update broke custom keymap
A few weeks ago I upgraded my Thinkpad x230 laptop with `pacman -Syu` and now the console login screen does not recognize keypresses. I'm prevented from using the device.
Here's my uname for reference
$uname -a
Linux arch 6.1.3-arch1-1 #1 SMP PREEMPT_DYNAMIC Wed, 04 Jan 2023 16:28:15 +0000 x86_64 GNU/LinuxFirst I tried plugging in an external USB keyboard but that didn't work either.
Next I booted into the live arch environment, mounted my root partition, chrooted into that, and enabled sshd as suggested by other posts. The keyboard works fine in the live environment, so I thought it it could be something with the kernel modules.
Here is the output of `lsmod` in the live environment:

serio 28672 7 serio_raw,atkbd,psmouse,i8042I've tried working through the diff using the `modinfo` command but that's been slow going. Most of the kernel modules names are cryptic and some don't have descriptions of what they do.
At this stage I tried to get an overview of how the keyboard and mouse work on linux and learned about the `evtest` utility. Interestingly pressing keys shows up there!

Re: [SOLVED] keyboard inoperable after kernel update broke custom keymap
This could be a kernel regression. Does downgrading the kernel fix the problem?

Re: [SOLVED] keyboard inoperable after kernel update broke custom keymap
I tried downgrading the linux package to a previous 6.0.X version and something in the 5.19.X range and neither made a difference.
There is also this output. Googling around made it seem like warnings of this sort were typically false alarms, but I seem to have several of them. I don't see an issue with the [keyboard] hook, but admittedly I'm out of my depth here

Are you using encryption ?
please post your etc/mkinitcpio.conf .
Disliking systemd intensely, but not satisfied with alternatives so focusing on taming systemd.
clean chroot building not flexible enough ?
Try clean chroot manager by graysky

Re: [SOLVED] keyboard inoperable after kernel update broke custom keymap
No encryption AFAIK. Here is my etc/mkinitcpio.conf
$ cat /etc/mkinitcpio.conf
# vim:set ft=sh
# MODULES
# The following modules are loaded before any boot hooks are
# run. Advanced users may wish to specify all system modules
# in this array. For instance:
# MODULES=(usbhid xhci_hcd)
MODULES=()
# BINARIES
# This setting includes any additional binaries a given user may
# wish into the CPIO image. This is run last, so it may be used to
# override the actual binaries included by a given hook
# BINARIES are dependency parsed, so you may safely ignore libraries
BINARIES=()
# FILES
# This setting is similar to BINARIES above, however, files are added
# as-is and are not parsed in any way. This is useful for config files.
FILES=()
# HOOKS
# This is the most important setting in this file. The HOOKS control the
# modules and scripts added to the image, and what happens at boot time.
# Order is important, and it is recommended that you do not change the
# order in which HOOKS are added. Run 'mkinitcpio -H <hook name>' for
# help on a given hook.
# 'base' is _required_ unless you know precisely what you are doing.
# 'udev' is _required_ in order to automatically load modules
# 'filesystems' is _required_ unless you specify your fs modules in MODULES
# Examples:
## This setup specifies all modules in the MODULES setting above.
## No RAID, lvm2, or encrypted root is needed.
# HOOKS=(base)
#
## This setup will autodetect all modules for your system and should
## work as a sane default
# HOOKS=(base udev autodetect modconf block filesystems fsck)
#
## This setup will generate a 'full' image which supports most systems.
## No autodetection is done.
# HOOKS=(base udev modconf block filesystems fsck)
#
## This setup assembles a mdadm array with an encrypted root file system.
## Note: See 'mkinitcpio -H mdadm_udev' for more information on RAID devices.
# HOOKS=(base udev modconf keyboard keymap consolefont block mdadm_udev encrypt filesystems fsck)
#
## This setup loads an lvm2 volume group.
# HOOKS=(base udev modconf block lvm2 filesystems fsck)
#
## NOTE: If you have /usr on a separate partition, you MUST include the
# usr and fsck hooks.
HOOKS=(base udev autodetect modconf kms keyboard keymap consolefont block filesystems fsck)
# COMPRESSION
# Use this to compress the initramfs image. By default, zstd compression
# is used. Use 'cat' to create an uncompressed image.
#COMPRESSION="zstd"
#COMPRESSION="gzip"
#COMPRESSION="bzip2"
#COMPRESSION="lzma"
#COMPRESSION="xz"
#COMPRESSION="lzop"
#COMPRESSION="lz4"
# COMPRESSION_OPTIONS
# Additional options for the compressor
#COMPRESSION_OPTIONS=()
# MODULES_DECOMPRESS
# Decompress kernel modules during initramfs creation.
# Enable to speedup boot process, disable to save RAM
# during early userspace. Switch (yes/no).
#MODULES_DECOMPRESS="yes"Following along from one of the links seth sent, which is a great match for my situation:
$cat /etc/vconsole.conf
KEYMAP=Caps2Escape.map$ls /usr/share/kbd/keymaps
amiga atari Caps2Escape.map i386 include mac pine ppc sun$ loadkeys us
Couldn't get a file descriptor referring to the console.I was running the above code via ssh, which I guess can cause issues?
That reminds me that I've also been getting this message at the ssh login:
Last login: Sat Jan 7 15:54:35 2023 from 192.168.1.135
Couldn't get a file descriptor referring to the console.
Couldn't get a file descriptor referring to the console.I did find that the following does solve the issue, but I'm not connecting all the dots to understand why this has broken and what will fix it.
$ sudo loadkeys -C /dev/console usHere's the contents of my custom mapping which worked fine previously.
$ cat /usr/share/kbd/keymaps/Caps2Escape.map
keymaps 0-2,4-5,8,12
keycode 58 = EscapeAs a side note, is there a way to read the man pages linearly or get an index of them?
I would never figure out that `man 5 keymaps` was an option on my own

Yes. The other user was operating on https://bbs.archlinux.org/viewtopic.php … 7#p2052387
Can you "loadkeys Caps2Escape.map" later on and does the problem go away if you remove the keymap hook and rebuild the initramfs?
As a side note, is there a way to read the man pages linearly or get an index of them?
You mean list all manpages?

Re: [SOLVED] keyboard inoperable after kernel update broke custom keymap
huh. it was as easy as `man -k .` very helpful
Okay, here is the full solution as I understand it for the benefit of the next person.
I guess I misinterpreted the following quote from the arch keyboard configuration wiki
As a side note, it is worth noting that such a personal keymap is useful also to redefine the behaviour of keys already treated by the default keymap: when loaded with loadkeys, the directives in the default keymap will be replaced when they conflict with the new directives and conserved otherwise. This way, only changes to the keymap must be specified in the personal keymap.
Based on that guidance, my Caps2Escape.map personal keymap only included the override.
$ cat /usr/share/kbd/keymaps/Caps2Escape.map
keymaps 0-2,4-5,8,12
keycode 58 = EscapeThis worked without incident for months, but for whatever reason isn't working now after a recent update.
The fix was to explicitly include the us keymap.
$ cat /usr/share/kbd/keymaps/Caps2Escape.map
include "/usr/share/kbd/keymaps/i386/qwerty/us.map.gz"
keymaps 0-2,4-5,8,12
keycode 58 = EscapeAnd for good measure I added an absolute path to my keymap environment variable based on `man 5 keymaps`
$ cat /etc/vconsole.conf
KEYMAP=/usr/share/kbd/keymaps/Caps2Escape.mapThen I regenerated the initial ramdisk environment
$ sudo mkinitcpio -p linuxAny idea what could cause this issue before I mark as closed? I don't want to be apprehensive about installing updates in the future.

Re: [SOLVED] keyboard inoperable after kernel update broke custom keymap
I'd assume the keymap hook moves the Caps2Escape.map into the initramfs, but not the us map, and so you're loading a very incomplete map.
A comparative lsinitcpio could tell.

Re: [SOLVED] keyboard inoperable after kernel update broke custom keymap
Thanks for the help. This was a frustrating issue but I learned a lot by digging into it.
