I have gone through the process mentioned in a 2017 post : Updated from 16.04 to 16.10; the keyboard and mouse no longer works after getting to the lock screen

I can get the mouse working, and then turn on the on-screen keyboard. But when I restart/turn off/ log out, I lose the mouse control and have to go through all the steps again.

Keyboard works in startup, and able to access CL in recovery mode. Read some errors while in recovery mode CL, so when I had logged into the system (and using the on-screen keyboard) I input the commands mentioned in previous posts.

Commands previously attempted:

"sudo apt install xserver-xorg-input-all" did not work

"apt full-upgrade -y apt install -y ubuntu-desktop apt install xserver-xorg-input-all" did not work

"sudo apt-get install --reinstall xserver-xorg-input-all" did not work

"sudo apt-get update && sudo apt-get upgrade" did not work

"apt-get update apt-get dist-upgrade update-usbids" did not work

I only have one kernel option under recovery mode.

Any assistance would be appreciated. At this point, I am tempted to just reload my Ubuntu image and not select to update to the latest version. The original image allowed my keyboard and mouse to work.

  • What is your kernel version now? Use uname -r to reveal. – WinEunuuchs2Unix Jul 24 at 15:37

The same problem was reported yesterday:

At the same time a related kernel problem was reported:

Hopefully this will be fixed in the next Ubuntu kernel update 5.0.0-21 but in the meantime use kernel 5.0.0-20. If you want to avoid reinstalling Ubuntu you can manually install the previous Linux Mainline/Stable kernel with these instructions:

The kernel before 5.0.0-21 in Ubuntu Speak is 5.1.16 or 4.19.59 in Linux Speak. When looking at the mainline kernels the important thing to remember is the dates. Anything dated July 21-23 is new one with bugs, anything around July 14 is the previous version:

  • Viola!! I downloaded version from 6.30.19, installed and it works now! Thank you very much, WinEunuuchs2Unix. – Richard Diring Jul 25 at 17:24
