Re: [Acer Travelmate B115-M] Synaptic touchpad

[Josep Pujadas-Jubany <jpujades@gmail.com>]

Benjamin,

I'm sorry. I just wanted to summarize the problem I reported at
bugs.launchpad.net

I followed the instructions that Ubuntu Team said to me,
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1493814/comments/33

The rest is only my ignorance about Linux Kernel. I'm sorry twice!

I will try to explain a new time the problem. I have no idea if it's
caused by the input module or not. Perhaps it is a problem of the i2c
module.

The Synaptic Touchpad is detected as SYN1B7D:01 06CB:2991 UNKNOWN with
default BIOS settings (i2c mode activated).

I tried this with the last version of the BIOS and latest kernel 64
bit available.

When this occurs the Touchpad works just like a simple mouse.

Thanks!

Josep
