USB keyboard not recognised at login after fresh 14.2 install


Hi,

I've done a fresh install of 14.2 a few times now and everything seems to go fine until I reboot to my new system and my USB keyboard isn't recognised.

Keyboard works fine in bios and all the way through installation.

I'm doing a full install from a USB stick; keeping the same partitions that worked just fine in 14.1; choosing automatic lilo install to the MBR (same as I had in 14.1). I do have a UEFI motherboard but I haven't changed anything in the bios since 14.1, either. I've tried choosing not to start gpm at boot. I've tried selecting the standard text console, in case that was the issue. I've tried passing acpi=off, nolapic, noapic and intel_iommu=on to lilo during setup, after googling similar issues. I'm out of ideas.

I don't have a spare ps/2 keyboard to test out and either there's also a problem with my networking setup or this issue is happening before that's initiated, so I can't even ssh into my machine to get any more information.

It seems like a trivial issue and I'm sure I'm just missing something obvious, but it's really frustrating!

Any help would be greatly appreciated.

Hello,

I do have some questions:

1. Is anything coming up in the system logs?
2. Do you get any error message?
3. Does the keyboard work in one of the TTY?

You could try one of the following during boot:

This should be a first attempt:
Code:
acpi=off
If that doesn't do it, try
Code:
nolapic
And finally, if the above worked, you can use
Code:
noapic pci=assign-busses apicmaintimer idle=poll reboot=cold,hard
this should result in all your CPUs being recognized.

Hi there,

Thanks very much for responding.

1. Sorry if it's a silly question but what logs do you suggest I look at? I can't review dmesg or any logs that are overwritten each boot, because I can't even log in to my new install without the keyboard. I CAN boot from the installation USB stick and mount my 14.2 hard drive and check out any logs that persisted from the last boot though, if you see what I mean.

2. I'm in a similar situation with error messages without being able to log in and type dmesg.

3. Can't switch to another tty without the keyboard!

I've actually tried acpi=off and nolapic already but I'll give it another go, and the longer string you suggested.

Cheers

Hey no problem...

I think it is systemd you should take a look it. You could possibly try to boot, until the keyboard fails, then you can boot from USB and check the logs.. It is strange that the keyboard works from the USB but not on the machine installation.

Some days ago, I did read something like what you mentioned on the Arch forums. There however mouse and keyboard were affected (USB and PS/2). It took some time, but they fixed it that way.However, I did overlook that you tried that already.. :P

Even though you made no changes to BIOS after the upgrade, have you checked it? Have you played around with the Hardware Settings? Though that does not necessarily explain why it works fine from USB but fails from the Hard Disk. Just another dumb question, have you disconnected your keyboard after boot and plugged it in again? Just to see if maybe a missing driver will kick in after it is connected again and rescanned?

I think we must have read the same thread on the Arch forum because that's where my previous attempts at turning off acpi came from!

And yeah, tried unplugging and replacing, and using different USB ports, still no luck. I'm pretty sure it's a more general USB problem than just my keyboard, but of course that's the one device I can't move on without.

I don't think Slackware has systemd (yet!) so it can't be that.

I tried all the boot options you gave me and still no change. I'll try digging into whatever logs I can access tommorrow, but might just end up borrowing a friend's ps/2 keyboard so I can at least troubleshoot this more easily from within the new installation.

Thanks again for your help so far.

Well sorry it did not work. I am not using Slackware myself.

Once you got the logs and find out something interesting, let me know. I will have a friend of mine, who also works with Linux Support, to have look at this.

Just a quick addition: did you try to unplug everything else connected to USB? Like webcam, controllers, even the mouse? Maybe something is conflicting with the driver of the keyboard?
