Comment 61 for bug 1058346

penalvch, I have created a new bug here as you had mentioned earlier.

https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1170883

I have attached all the details there. I am repeating all the details here again for your reference.

The touchpad is not even detected when I do

$ xinput list

The trackpad is not even listed. I get the following output:-
===============================================================================

⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ Microsoft Microsoft Basic Optical Mouse v2.0 id=10 [slave pointer (2)]
⎣ Virtual core keyboard id=3 [master keyboard (2)]
    ↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)]
    ↳ Power Button id=6 [slave keyboard (3)]
    ↳ Video Bus id=7 [slave keyboard (3)]
    ↳ Power Button id=8 [slave keyboard (3)]
    ↳ Sleep Button id=9 [slave keyboard (3)]
    ↳ HD WebCam id=11 [slave keyboard (3)]
    ↳ AT Translated Set 2 keyboard id=12 [slave keyboard (3)]
    ↳ Acer WMI hotkeys id=14 [slave keyboard (3)]

===============================================================

The Microsoft Basic Optical mouse is an external USB mouse that I am using. It has nothing to do with the trackpad.

BIOS version 1.05 found out using the following command:-

$ sudo dmidecode -s bios-version

$ lsb_release -rd
