I've been having a rough day, working on this, and coming up short. It's taken a lot of reboots, which wear me down in particular.

Here is the xinput with the wireless usb device plugged in.

⎡ Virtual core pointer                              id=2    [master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer                    id=4    [slave  pointer  (2)]
⎜   ↳ Microsoft Microsoft® Nano Transceiver v2.0    id=10   [slave  pointer  (2)]
⎜   ↳ Microsoft Microsoft® Nano Transceiver v2.0    id=11   [slave  pointer  (2)]
⎜   ↳ PixArt USB Optical Mouse                      id=12   [slave  pointer  (2)]
⎣ Virtual core keyboard                             id=3    [master keyboard (2)]
    ↳ Virtual core XTEST keyboard                   id=5    [slave  keyboard (3)]
    ↳ Power Button                                  id=6    [slave  keyboard (3)]
    ↳ Power Button                                  id=7    [slave  keyboard (3)]
    ↳ Sleep Button                                  id=8    [slave  keyboard (3)]
    ↳ Microsoft Microsoft® Nano Transceiver v2.0    id=9    [slave  keyboard (3)]
    ↳ CHICONY USB Keyboard                          id=13   [slave  keyboard (3)]
    ↳ CHICONY USB Keyboard                          id=14   [slave  keyboard (3)]
    ↳ Microsoft Microsoft® Nano Transceiver v2.0    id=15   [slave  keyboard (3)]

I then enter the following commands, and see the resulting xinput, and I see the other pointer on the screen, either as a cursor or standard pointer, and it is blinking, and it jitters as i type on the first, wired usb keyboard, but the neither the touchpad or the keyboard of the wireless device are working as might be expected. It's a Microsoft All-in-one Media Keyboard. I'm using Ubuntu 18.04.1 (and I feel I should note I chose the "minimal install" from the start.) It may also be of note that I'm using two monitors from 1 16-lane GPU. Thank you for any help you can give.

Then I found the power button, and all is well.

  • The power on the keyboard was turned off for all the configuration tinkering. After turning the power on the keyboard, it worked right away, even without configuring, just plugging the USB receiver into the mainboard. – tidelake Oct 15 '18 at 8:10
