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.
