Interesting - I think this must not be a kernel problem. While trying to do the bisection testing, I accidentally removed some needed drivers, so I just reinstalled 13.10.
When I originally installed 13.10 (from the same USB drive), the trackpad was definitely working, but now it is not. I think there must be some firmware/BIOS/something setting that somehow gets reset when the battery dies? I don't have Win 8 anymore on this computer, so I can't test Todd's fix, but I would be very, very interested if anyone has any ideas about how to get Ubuntu to recognize my trackpad again! -- 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/1244716 Title: Trackpad not detected; Asus K55N (AMD) Status in “linux” package in Ubuntu: Incomplete Bug description: Following upgrade to 13.10 my trackpad was working fine, but I had been having suspend issues. Apparently, last time I closed the lid on the laptop, it didn't suspend, as when I retrieved it today, it was dead. After starting the computer, the trackpad was no longer working. I do not think that this was following a kernel upgrade, but the page at https://wiki.ubuntu.com/DebuggingTouchpadDetection suggested that non-detection is a kernel issue. I don't really know much about kernel bug reporting, so forgive me if I'm doing anything wrong. :) ProblemType: Bug DistroRelease: Ubuntu 13.10 Package: linux-image-3.11.0-12-generic 3.11.0-12.19 [modified: boot/vmlinuz-3.11.0-12-generic] ProcVersionSignature: Ubuntu 3.11.0-12.19-generic 3.11.3 Uname: Linux 3.11.0-12-generic x86_64 NonfreeKernelModules: fglrx ApportVersion: 2.12.5-0ubuntu2.1 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC1: jeremy 1933 F.... pulseaudio /dev/snd/controlC0: jeremy 1933 F.... pulseaudio Date: Fri Oct 25 09:10:26 2013 HibernationDevice: RESUME=UUID=5249f486-fcac-4cc6-9289-34125a4b4f1f InstallationDate: Installed on 2013-10-21 (4 days ago) InstallationMedia: Ubuntu 13.10 "Saucy Salamander" - Release amd64 (20131016.1) MachineType: ASUSTeK COMPUTER INC.
