After upgrading from Ubuntu 14.04 to 14.10, I am no longer able to use my keyboard and mouse to do anything. I can't even get to a tty terminal. All I can do is stare at the login screen, or do a hard reset.

I suspect the Linux kernel 3.16 because my keyboard and mouse work again after booting into an older kernel version from Grub's 'Advanced Ubuntu Options' page.

My computer is a custom built PC with an AMD chip-set and USB 2.0 and 3.0. (Built around the first of October 2014)

Edit: My keyboard is a USB HP keyboard from another computer, my mouse is a USB wireless Logitech mouse with unifying receiver.

Edit2: Clarified information about not being able to use keyboard or mouse to do anything.

  • What type of keyboard and mouse do you use? Wireless? USB? PS/2? I don't imagine you use a serial mouse or DIN keyboard... – Jan Oct 28 '14 at 22:11
  • I've updated my post to answer your question. – RJ-Adam Oct 30 '14 at 14:39
  • Do I get you right: You press ctrl-alt-f1 you don't get a tty and that only happens with 3.16 and not with earlier kernels? You also mention the mouse, so my bet is that it's a USB issue... – Jan Oct 30 '14 at 14:43
  • Correct. I also get this problem with the Grub 'recovery mode' for kernel 3.16. I have keyboard control in Grub, but not in the recovery environment. – RJ-Adam Oct 30 '14 at 14:50
  • Do keyboard and mouse work in GNOME? Can you please boot normally, log in and then open a terminal window and paste the output of sudo dmesg |grep input and sudo lsmod|grep usb? – Jan Oct 30 '14 at 15:01
  • Is there some way to setup a script that runs on startup and displays error or boot information from a log file? – RJ-Adam Oct 30 '14 at 15:13
  • No, I am unable to login because the keyboard doesn't work. I'll clarify that in my post. – RJ-Adam Oct 30 '14 at 15:16
  • Does it work if you pull out the keyboard and plug it in again when seeing the login screen? – Jan Oct 30 '14 at 15:22
  • Nope. Initially, there is the num-lock light on my keyboard. When I unplug and plug it back in, the num-lock light doesn't turn on. – RJ-Adam Oct 30 '14 at 15:24

I had the same issue - for some reason, during the upgrade, my kernel was skipped so I manually upgraded/installed linux-image-3.16.0-24-generic. It turns out most of the drivers you need live in linux-image-extra-3.16.0-24-generic and you'll need the headers too. I'm guessing you're missing them as I was.

So, from your working kernel:

sudo apt-get install linux-image-extra-3.16.0-24-generic linux-headers-3.16.0-24-generic

Afterwards you should be able to boot into 3.16 and your peripherals will work as expected.

  • Thanks, this helped a lot! For me though, it was the linux-image-extra package which installed the usbhid driver. As I understand, the headers package should only be needed for compiling modules (and possibly other software that relies on kernel ABIs). – Alex Forbes Dec 18 '14 at 19:16
  • Same fix worked for my Ubuntu 12.04.2 upgrade to 14.04.3 except I had to change the kernel version to 3.19.0-30. – Lucas Oct 10 '15 at 03:58

I kind of had the same issue after upgrading. But I could get to tty and by accident found out that GNOME Do was the application to blame for that the keyboard (and mouse) stopped working.
