my touch pad doesn't wok at all.

[Ajmain Fayek]

i'm new at linux. firstly i have installed ubuntu as dual boot besides windows 11 pro. that time the touchpad worked as expected. but when i gain confident enough that i can use linux, i installed ubuntu as primary setup, after that the touch pad is not working.
it detects the touch pad as follows

cat /proc/bus/input/devices
