Comment 27 for bug 2060868

The problem is that on upgrade to Noble the package linux-image-laptop is removed which contains config settings for the machine. I'm in the process of creating a new package (ubuntu-x13s-settings) for Noble that provide these settings. Can you try to install ubuntu-x13s-settings from PPA:ubuntu-concept/x13s (https://launchpad.net/~ubuntu-concept/+archive/ubuntu/x13s) and report back?

One of the issues is that ARM pointer authentication is not working (broken Lenovo firmware) and needs to be disabled for the 6.8 kernel (arm64.nopauth kernel commandline option). The above package should set that (amongst other things).
