Hi Cara, and Davide, I was talking to another member of the kernel team, and he mentioned he was working on an issue that seemed very similar to the issue you both have hit. After looking into it more deeply, we are sure that they are the same issue. He has made more progress on the issue, and has reproduced it. I will be marking this ticket as a duplicate of https://bugs.launchpad.net/bugs/2080355 and @vpeixoto will continue the investigation. ** This bug has been marked a duplicate of bug 2080355 Kernel trouble, with some trace, 6.8.0-44-generic -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/2076986 Title: Lenovo Touchpad not working or detected in 'Lenovo Legion 9 16IRX9' following Ubuntu 22.04 installation. Status in linux package in Ubuntu: Confirmed Bug description: The Lenovo Legion 9 touchpad on my laptop is unresponsive after installing Ubuntu 22.04. How might I get it working again? A lot of solutions suggested to downgrade the kernel but the posts I found were from 2+ years ago. Below is the output from 'cat /proc/bus/input/devices'. Note that the Logitech mouse is a (functional) wired mouse I was using at the time.
