rated 0 times [ 8] [ 0] / answers: 1 / hits: 17184 / 1 Year ago, sun, march 12, 2023, 6:05:28

I am currently on ubuntu 22.04 LTS release which comes with kernel version 5.15.0-27-generic. I want to downgrade to kernel version 5.13 because of touchpad problem in my lenovo thinkbook.

Is it possible to downgrade the baked in kernel in 22.04 LTS release? If yes, how do I achieve it?
