Ubuntu: How to fix touchscreen on my Acer c720p


I have an issue with the touchscreen of my Acer c270p (it's a Chromebook).

The past two weeks, I was using chrome OS AND ubuntu thanks to crouton, but to save place, I decided to entirely remove Chrome OS and to install a fresh ubuntu distribution. I installed Ubuntu 14.04 64 bits with unity. After the install, everything was working fine except two things : the touchpad and the touchscreen.

I followed this tutorial to fix the touchpad and I added this lines to set up the sensibility in the /usr/share/X11/xorg.conf.d/50-cros_touchpad.conf file :

Section "InputClass"       Identifier      "touchpad peppy cyapa"       MatchIsTouchpad "on"       MatchDevicePath "/dev/input/event*"       MatchProduct    "cyapa"       Option          "FingerLow" "10"       Option          "FingerHigh" "10"   EndSection  

And now the touchpad work fine but I don't know how to fix the touchscreen. Does someone have an idea ? Do you think that it will be fix with the kernel of Ubuntu 14.10 ?



This answer is probably a litte late, but (thanks to the author lukabirsa ) there is a great script HERE on how to install Ubuntu 14.04 on the Acer C720 and C720P (with many links to additional fixes for Kernel 3.13).

Have a nice weekend.

P.S. if you run Kernel 3.17 or newer, you don't need to fix the Touchpad and Suspend functionalities. On the opposite, I have no idea how to put the Touchscreen to work, but I'm working on it...
