Keyboard doesn't work at login

bimbambo · 2023-01-01 17:00:28

Hello,

My arch install on thinkpad x220 doesn't let me type when I arrive at login in tty since a week or so.
Caps lock led does respond. USB keyboard also doesn't work and I can't switch tty.
The keyboard still works at GRUB menu. I have booted into live USB and used command "sleep 5; journalctl -b | curl -F 'file=@-' 0x0.st" to get log as described in https://bbs.archlinux.org/viewtopic.php?id=278864. Output is at 0x0.st/oRX-.txt. Please tell me if more information is needed.

There's no obvious problem in that journal.
1. does the lts kernel still work?
2. try adding "i8042.dumbkbd=1" to the kernel commandline (though I don't see how this would help if an external keyboard fails as well. That's not in the journal, though?)
3. NM drags in wpa_supplicant but you also have iwd enabled, disable the latter or use https://wiki.archlinux.org/title/Networ … Fi_backend (it's a stretch, but hey…)

Thanks for the quick response

1. I installed the lts kernel and chose it in advances options in grub but it still doesn't work.
2. That doesn't work. I tried typing with USB keyboard earlier, but I can plug it in and upload the log if needed.
3. Disabling iwd also doesn't work.

So an older kernel doesn't work and an external keyboard doesn't work either.

My arch install on thinkpad x220 doesn't let me type when I arrive at login in tty since a week or so.

What happened a week ago (or so)?
Did you possibly update the BIOS?
Was systemd updated around that time (check your pacman log)?

13 december after 2 months of no upgrading I did a full system upgrade and systemd was updated from 251.6-2 to 252.3-1 and kernel from 6.0.2. to 6.0.12.
I also kept getting the error message: WARNING: Possibly missing firmware for module: xhci_pci.
I did not update BIOS.

251.6 will get you into trouble b/c of the openssl bump, but you should™ be able to downgrade to 251.7-4

Edit: make sure you've some bootable live system at hand (install iso, grml, …)

I downgraded systemd. Do I have to downgrade the systemdlib package seperately?

The systemd package doesn't version that dependency, but downgrading systemd-libs in sync would seem wise.

bimbambo · 2023-01-03 10:44:18

I have downgraded systemd-libs as well, but this didn't fix the problem.

* Neither the kernel nor systemd are relevant.
* Internal and USB keyboard are affected (not? the BUS)
* Keyboard works in GRUB (not the HW)

1. Try some live distro (grml) for an entirely differen SW stack.
2. Script the session to auto-run "libinput debug-events" and see whether that produces any output (w/ and w/o your interaction)

bimbambo · 2023-01-03 17:09:09

1. I don't understand why I need to use a live distro and what I would have to do after that?
2. It first showed some lines with -event2 DEVICE_ADDED Poser Button seat0 default group1 cap:k.
For Power Button, same for USB Keyboard, AT Translated Set 2 keyboard and more.
When I started typing it said: event3 KEYBOARD_KEY ... pressed
for the USB keyboard and event 5 in the case of thinkpad keyboard.

seth · 2023-01-03 17:31:09

To try some entirely different software and rule out some weird HW issue, however libinput correctly reports input.
Maybe this is just a visual thing?
If you from the autologin (blindly) enter "systemctl reboot", does the system reboot?
Does the "keyboard" work if you boot the multi-user.target along the "nomodeset" kernel parameter?
(2nd link below)

Edit: though you're apparently getting something of an output…

systemctl reboot doesn't work neither does using nomodeset and systemd.unit=multi-user.target as kernel parameters.

What does your vconsole.conf look like?
What if you autorun "loadkeys us" ?

bimbambo · 2023-01-03 18:47:58

That solved it. I had a personal map in vconsole.conf because I wanted to use CapsLK as Esc key in tty. I changed it to us qwerty and now I can type again.
Thank you very much!

seth · 2023-01-03 20:54:44

Did the map previously work and/or does it work if you load it at runtime?
This might be because of the recent mkinicpio hook changes, specifically the keymap addition.

Please always remember to mark resolved threads by editing your initial posts subject - so others will know that there's no task left, but maybe a solution to find.
Thanks.
