Update: I'm still having trouble with this. To reiterate my keyboard and trackpad once worked both in the live OS from the USB and after the installation. Something changed after a few nixos-rebuild switch
calls, and I haven't been able to revert the changes.
If anyone has any pointers for troubleshooting, I'm eager to hear them.
I'm observing a very similar issue on my Thinkpad s230u. The keyboard, touchpad and trackpoint cease to work after using either the touchpad or the trackpoint. Those devices disappear from the list returned by xinput
.
The symptoms only appear roughly 80% of the time. Using an external USB keyboard and mouse works fine.
The same thing happens with a fresh Debian live with kernel 4.20 and NixOS with kernel 4.19. This problem appeared somewhat recently, one or three months ago on NixOS.

Your comment can be as simple as "still important to me". This lets people see that at least one person still cares about this.

I'm still observing this issue on NixOS 20.03 with kernel 5.4.43. Disconnecting the touchpad and trackpoint on my Thinkpad seems to allow the keyboard to work.

I have a very similar issue on nixpkgs-unstable, it's been a month that all my nixos-rebuild switch
gives me a generation on which my laptop keyboard and touchpad are not working, however the touchscreen and any external devices (mouse, keyboard) are working.
I can still boot on the older generations to have a working keyboard though.

I'm experiencing the same issue on iLo4 on a HP Proliant Microserver Gen8. By setting intremap=nosid
and intel_iommu=off
I was able to use the keyboard again as outlined here: https://serverfault.com/questions/1077297/ilo4-and-almalinux-centos8-do-not-work-properly
Describe the bug My keyboard recently stopped working. I tried rolling back to previous versions when my keyboard did work, but it appears the issue persists.
My keyboard fully works in BIOS but nowhere else.
I've tried asking for troubleshooting advice elsewhere, but I'm starting to think that this may be an issue with the Linux kernel. If anyone's interested, here's the thread.
To Reproduce Steps to reproduce the behavior:
Expected behavior I expect to be able to use my laptop keyboard. I believe this is a drivers issues. Unfortunately, I'm unsure how to troubleshoot Linux keyboard drivers in general and on NixOS specifically; otherwise, I'd begin that process. Any pointers much appreciated.
Additional context Tools I've used to attempt to debug:
xev
- nothing happenssudo evtest <event>
- Tried this for all 21/dev/input/event*
options. Nothing observable except that theBrightnessUp
andBrightnessDown
key events are recognized. I ran this in X and outside of X to eliminate a variable.sudo hexdump <event>
- Tried this too for all 21/dev/input/event*
. Nothing of note. This was maybe an unnecessary test.xinput list
- Just to get a human readable list of inputs. In case anyone's interested, here's that output:Metadata

Linux 4.19.60, NixOS, 19.03.173182.96151a48dd6 (Koi)

I'm using an Acer Aspire a315 in case that makes a difference. I've also read non-Linux-related forums about this issue and some Windows10 users recommend upgrading the keyboard drivers. Does anyone know how to do this in NixOS? This is a foreign concept to me.
Again: any pointers are graciously welcome!
