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.
