Ubuntu – Keyboard not working at login screen Ubuntu 14.04

14.04keyboard

I'm running Ubuntu 14.04 with gnome 3.9.90. After a standard program update two weeks ago my keyboard stopped working only in the login screen. As a workaround I log in using the screen keyboard. When I'm logged in everything works fine.
I've tried to boot in recovery mode and with older kernel, but it's the the same result.

Any suggestions how to fix/debug this?

Maybe try working through these solutions? They are for problems after coming back from suspend, but maybe a start.

Ubuntu – 14.04 keyboard and mouse stopped working at login screen

This post doesn't ask a clear question, but the title is exactly what happened to my machine, albeit running ubuntu 16.

I had upgraded, and while the box booted to the lightdm login screen, keyboard and mouse (laptop internal, also I tried plugging in usb) were non-responsive. After a time the cursor in the password field stopped blinking as well.

It appears some X packages had been incorrectly deleted when i ran an apt autoremove (necessary due to a full /boot drive).

re-installing apt install xserver-xorg-input-all fixed the issue for me.

(to install this, boot into recovery mode, enable networking, and drop into the root shell. When completed, reboot.)

First, check if Slow Keys is turned off in the Accessibility menu on the top right. If it's already turned off, try:

    sudo apt-get install xserver-xorg-input-all

If it's already installed, reinstall it:

    sudo apt-get --purge autoremove xserver-xorg-input-all
    sudo apt-get install xserver-xorg-input-all
