Thank you for taking the time to report this bug and helping to make Ubuntu better. Unfortunately, we cannot work on this bug because your description didn't include enough information. You may find it helpful to read "How to report bugs effectively" http://www.chiark.greenend.org.uk/~sgtatham/bugs.html. We'd be grateful if you would then provide a more complete description of the problem.

We have instructions on debugging some types of problems at http://wiki.ubuntu.com/DebuggingProcedures.

At a minimum, we need:

1. The specific steps or actions you took that caused you to encounter the problem.
2. The behavior you expected.
3. The behavior you actually encountered (in as much detail as possible).

Thank you!

Launch Pad is not detected by Linux Kernel

1. After a fresh installation of Ubuntu 22,04 LTS, replacing a previous windows 10, I found that the touchpad was not working. on further analysis i foubnd out that the hardware was not listed in the kernel. Please see attached screenshot.

Expected behavior: Linux distro recognizes mouse touchpad,

Actual Result: Touchpad is not recognized and is not working.
