I'm wrong.
3.19.0-51 is the last version I found where the touchpad works.
All higher versions (including 3.19.0-56) are not ok

Touchpad is SYN1B7D:01 06CB:2991 and SYN1B7D:01 06CB:74D9
I don't know where the second type number comes from. The devices are Acer B115. Acer has upgraded the firmware of the touchpads due to erratic cursor behaviour. Next time I looked, the 2991 seemed to have changed to 74D9.

I have exactly the same problem, using Acer ES1-411-C5D2 running Ubuntu 14.04: kernel 3.19.0-51, the touchpad works ; kernel 3.19.0-56, the touchpad does not work

Same here with an Acer ES1-131. The touchpad works fine with 3.19.0-51 (14.04 LTS), stopped working after the update to Kernel 3.19.0-56.

I am affected by the same problem. My laptop is an acer e3-112-c43a.

Today tried live boot of 16.04 on my Asus X205TA and the touchpad works. The kernel is 4.4.0-15.

I am on 4.4.0-15.31 and my device is a Asus UX32VD laptop. My touchpad also stopped working. I'm running Ubuntu 14.04 and installed the 4.4 kernel through the linux-image-generic-lts-xenial package, and it's been working without problems up until yesterday.

I was able to regain some functionality using this solution: http://askubuntu.com/questions/262287/synaptic-touchpad-on-laptop-not-working

But the touchpad remains sluggish and scrolling does not work.

If you guys are affected, please make sure you have checked the questions "Does this bug affect you?" above. Then this bug will collect points and be fixed earlier.

I have the same problem with a not functioning touchpad on Acer Aspire V11 Touch, running 14.04 LTS after updating to 3.19.0-56. 3.19.0-51 is the last update that works. The touch-screen works fine hough...

I can confirm Zanna's solution for the Acer B115
apt-get install linux-image-generic-lts-xenial linux-headers-generic-lts-xenial, resulting in kernel 4.4.0-15-generic solved the problem.
So the 4.4.0.-13.7 and 3.19.0-56 are not ok, the 4.4.0-15-generic #31~14.04.1 is ok

Hi there,
I would like to add further details on this issue I'm experiencing on an Acer Aspire ES1-711-P0HA. It has been worked fine up to kernel 3.19.0-51, then no working touchpad from 3.19.0-56 onwards.

Following two excerpts of "dmesg" and "syslog" for each kernel 3.19.0-51 and 3.19.0-58. As you can see the ELAN0501:00 04F3:300B touchpad device is recognized from the -51 kernel, whereas the -58 kernel times out the 80860F41:00 controller and isn't be able to initialize the device driver.
For sake of completness I have to report just one unrepeated event where the touchpad has worked with kernel -56.
A last detail, that I found at least unusual, is that the kernel 3.19.0-51 has been compiled with gcc version 4.8.4, whereas the last kernel version 3.19.0-58 has been compiled with the previous gcc version 4.8.2.

In relation to my previous post: the latest kernel 3.19.0-59 solved my issue. The touchpad is now working back on Aspire ES1-711-P0HA.
