[Bug 1327153] Re: Touchpad stopped working in 3.13.0-29


Would it be helpful if I bisect the kernels in your link below to see which version it starts working again?

I am not sure how to determine the kernel version number from the names though. For example
v3.13.11.2-trusty is the last 3.13 version there. Is there a file inside the tells the ubuntu-version numbering?
