My TouchPad is not responding on an Acer Aspire E1-471-6650

I recently bought an Acer Aspire E1-471-6650 and I already have problems. First, when I tried to use the touchpad on a LiveCD, it wasn't responding. When I installed it in my notebook, it wasn't responding either. I was browsing for solutions and I couldn't find a solution for it. When I write xinput command:

⎡ Virtual core pointer                     id=2     [master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer           id=4     [slave  pointer  (2)]

I tested these solutions:

I was able to enable/disable this with Fn+F7.

I wrote in final of paragraph of sudo nano /usr/share/X11/xorg.conf.d/50-synaptics.conf:

Section "InputClass"
   Identifier "touchpad catchall"
   Driver "synaptics"
   MatchIsTouchpad "on"
   Option "TapButton1" "1"
   Option "VertEdgeScroll" "1"
EndSection

Can somebody help me? .. thanks!

Solution 1:

You might try enabling the touchpad with Ctrl+Fn+F7 instead of just Fn+F7. I had to do this with my Acer Aspire E431.
