After Installing Zorin OS 16 in my Lenovo Ideapad laptop my Keyboard & Touchpad are not working.
My System Details:
Laptop: Lenovo G500 (Ideapad)
BIOS Version: 78CN25WW(V2. 03)
EC Version: 78EC19WW(V1. 07)
CPU: Intel(R) Core i5-3230M 2.60GHz
RAM: 12 GB
HDD: 500 GB
See if this askubuntu thread helps:
Check your bios settings and reset them to their default. Also, in the terminal check the list of hardware via xinput command and enable and disable hardware.
If the suggestions above, including the boot parameters
atkbd.reset=1 i8042.nomux=1 i8042.reset=1 i8042.nopnp=1 i8042.dumbkbd=1 do not help, you also can try:
sudo apt remove xserver-xorg-input-all
sudo apt install xserver-xorg-input-all
