I am totally new to Linux and just bought a new computer with windows 8.1 preinstalled. I wanted to install Linux Mint 17 Cinnamon 64 bit as a dual boot system alongside windows since I didn't like windows 8.1 and want to try Linux. I have now successfully installed Linux Mint Cinnamon and it is working fine except that the touchpad on my laptop is not working. I am using an USB mouse to write this and that works fine. The strange thing is, if I boot into windows 8.1 the touchpad works fine.

I tried running the update manager, downloading all the package files and restarting the system but the touchpad still isn't working.
I have tried the Fn+F7 function on the keyboard that is supposed to switch the touchpad on and off, that didn't change a thing.
I have opened the "Mouse and Touchpad" settings and the touchpad is set to be enabled.
I have tried downloading and removing one by one several of the touchpad packages listed in the Synaptic Package Manager under "Not Installed" and none of that helped.

Despite what changes I have done this is what always comes up when I run the xinput list command:

mint@mint ~ $ xinput list
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ id=11 [slave pointer (2)]
⎜ ↳ Logitech USB Gaming Mouse id=12 [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=10 [slave keyboard (3)]
↳ AT Translated Set 2 keyboard id=13 [slave keyboard (3)]
↳ Acer WMI hotkeys id=14 [slave keyboard (3)]
mint@mint ~ $

As you can see the mouse is detected but nothing on this list indicates to me that the touchpad is detected.


I have searched the Linux Mint forums and the Unbutu forums for solutions for this problem but have not found any. I have spent days trying to solve this and am about to give up because I suspect my computer is just not compatible with Linux. It's a brand new one. The information is below.

The computer I am using is an Acer Aspire E 17. It has this number on the sticker: E5-721-2474 Here is more info:

I'm not knowledgeable in this, but you may want to try searching for threads or web threads about adding a touchpad to the xorg configuration files. I don't if it will want a driver specification there - if it does I don't know what it may be.

EDIT: Just did some searching on the net and really didn't find anything for the current version of Ubuntu, and since you are using Mint it should be the same. I went to Acer and to your model (E5-721) but the only OS they show is Windows 8.1. There isn't a driver listed there for the touchpad. There are some hits on the net that show replies for older versions of Ubuntu, but I wouldn't have a clue as to whether those apply to the latest version.
