Unfortunately, I removed the former kernel to save space and I don't remember what was its version, I tried previous kernel versions (3.11.0-[12,13,14,15]-generic) and my touchpad doesn't work with any of them.
I also tried the latest v3.13 kernel, which does not solve the problem ** Changed in: linux (Ubuntu) Status: Incomplete => Confirmed ** Tags added: kernel-bug-exists-upstream -- 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/1266186 Title: Touchpad not detected anymore in 'HP ChromeBook 14-q030ef' after the kernel upgrade Status in “linux” package in Ubuntu: Confirmed Bug description: My laptop touchpad stopped working after a kernel upgrade 2 days ago, it worked correctly before that. I didn't find any shortcut to enable/disable it, and since it's a chromebook, it doesn't have a BIOS. Also, the touchpad works when I boot on ChromeOS. My mouse still works.
