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). -- 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/2060868 Title: Lenovo X13s fails to boot on 6.8.0-20-generic and 6.8.0-22-generic Status in linux package in Ubuntu: Confirmed Status in linux source package in Noble: Confirmed Bug description: The last kernel that successfully boots on my Lenovo X13s system is 6.5.0-1004-laptop.
