[Bug 1393079] Re: Touchpad not working after suspend/resume

 

Bernhard, sorry, my bad. I left out one important step. Before compiling you should also edit the file linux-3.16.0/debian.master/changelog and change the version number in the first line to, e.g., 3.16.0-30.40+hidfix
Without this, the updater tries to update the newly compiled kernel, even though it has the same version number. Also, there was a kernel update from 3.16.0-29 to 3.16.0-30 sometime within the last 24 hours which still does not include the patch.
If you still want to do build the new kernel, delete the old source, update the system and redo all the steps to compile the kernel including the above addition. And remember that you will have to do this every time there is a kernel update.

Title:
  Touchpad not working after suspend/resume

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  Ubuntu 14.10 on an Acer Laptop, model: Aspire E5-571G-941Y
  $ uname -a
  Linux Acer-Aspire-E5-571G 3.16.0-24-generic #32-Ubuntu SMP Tue Oct 28 13:07:32 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux

  Every time I suspend, the trackpad no longer works when resuming.

  I see several other people have the same issue with the same laptop here:
  http://ubuntuforums.org/showthread.php?t=2250002
  (some people say it's a 14.10 specific problem)

  I realize this report is very poor but please don't hesitate to request data / clarifications from me, I'll be happy to help.
