Sadly, I have to correct myself - I thought I had replicated the issue, but it turns out my particular laptop doesn't use USB to attach the mousepad. I tried plugging a USB mouse into my system while running a "bad" kernel, and it was able to wake from suspend when I moved the mouse. Also, it appears my system is using s2idle. So sadly, I cannot reproduce the bug on my hardware after all.
What I can do is leave a hint for the next person who goes to bisect the kernel. Due to a change in initrd compression, if you try to install a kernel that's too old onto Ubuntu Jammy or Kinetic, it won't be able to boot since it won't be able to mount the initrd image. To fix this, do "sudo nano /etc/initramfs-tools/initramfs.conf", and change the "COMPRESS" option to "gzip" (it will probably be set to "zstd" by default). That should get your older kernels booting, so you can actually have a fighting chance at bisecting the kernel. Sorry I couldn't do it myself on my hardware. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1971933 Title: [Regression] Unable to wake laptop using trackpad input To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1971933/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
