After systemwide upgrade, laptop keyboard doesn't work

The title is pretty much my entire set of symptoms. This happened about an hour ago. I don't have a bootable image handy, so I can't even see a log yet (I'll make one when I get home). But CTRL-ALT-f(n) are all ignored.

Slim's "Login:" splash screen is displaying at a much lower resolution than usual, and the cursor is not blinking in the Username: field. I am, temporarily at least, completely locked out.

FWIW, system is a Thinkpad X220. And I have a feeling this has nothing to do with slim... power save/screen saver has kicked in and won't leave, it's like all forms of input are ignored. Like X is not fully working.

More to come once I figure out a way in.

[EDIT: title updated to reflect more information]

You can temporarily add the kernel command line option 'systemd.unit=multi-user.target' from your boot loader to get a login prompt to a console.

Thanks - that advanced me a step... but I can't log in to the console either; the keyboard is not working once it's booted (though it was during systemd's prompt, obviously).

The plot definitely thickens.

[EDIT: I can now get to a systemd rescue shell, with working keyboard. Where is a good place to start poking?]

[EDIT 2: can now boot into multi-user.target and log in OK, the keyboard started working on subsequent boots. But no input in X when I start it by hand.]

OK, I suspect this is the wrong forum. There is other stuff going wrong as well, it's not just my login manager or something related. Apologies.

Some logs would be helpful. The list of packages you upgraded, Xorg log, etc...

Re: After systemwide upgrade, laptop keyboard doesn't work

I've narrowed it down to linux versions.

linux-3.14.2-1: works fine
linux-3.14.4-1: no network interfaces, no keyboard or mouse in X
linux-3.14.5-1: also no joy

I'll upgrade to 3.14.4 again and see what interesting logs turn up.

Also: Not intentionally crossposting, just realising my original thread (this one) was not about the right thing and thus not in the right place. But this one will do fine.
