Microsoft Natural Ergonomic Keyboard 4000 not working in Ubuntu 22.04 LTS

la flag

I updated from Ubuntu 20.04 LTS to Ubuntu 22.04 LTS and the keyboard did not work anymore. I had to use the onscreen keyboard to log in. I had a spare keyboard which works, but the Microsoft keyboard is stuck. None of the keys are working.

I have searched the Internet and found no similar problem.

I have tried the following:

  • find a driver
  • settings -> add keyboard layouts
  • install keytouch - does not exist
  • install xserver-xorg-input-all - already installed
  • different USB port

The keyboard work in boot, but after that it's not working.

Funny thing: I run Virtualbox 6.1.42 and inside a running machine, the keyboard is working fine. I actually run Ubuntu 22.04 LTS inside Ubuntu 22.04 LTS. The keyboard is working inside the guest, but not in the host OS.

Virtualbox USB device Doesn't look like the keyboard is locked to Virtualbox.

I solved it by I mistake. Because my sound device was not found by aplay, but the system and ALSA found the sound cards. After reading different post this code fixed the sound problem:

sudo apt install linux-modules-extra-`uname -r`

And that code also fixed the missing keyboard. My Ubuntu was missing extra kernel modules.

Check setting of VMs. Maybe the USB device is in the list dedicated to the guest.

Ubuntu is missing extra kernel modules. To install the missing kernel modules open the terminal and type:

sudo apt update  
sudo apt install linux-modules-extra-`uname -r`

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
