Have you just install Ubuntu on your Chromebook and your track-pad is aka broken or did not work. Now you have to suck it up and use a mouse or went back to ChromeOs because of this reason. I'm here to save your day. Listed below is step-by-step to fix your track-pad problem.



Track-pad Fix:


1. Open Terminal and gain access to root:

Sudo -s

2. Once you have login as a root user:

nano -w /etc/modules
or
sudo gedit /etc/modules

3. Add the following lines in this order:

loop
lp
rtc
i2c-i801
i2c-dev
chromeos-laptop
cyapa


4. Save (Ctrl-O)

5. Reboot

*Note if you are run Ubuntu 14.04 the track-pad should work once your system boots back up. If so skip to 10.

6. Log back in to the terminal as a root user:

Sudo -s

7. Download 64 bit kernel 3.11:

*Note if you need the 32 bit kernel I will have it listed below.

wget -c kernel.ubuntu.com/~kernel-ppa/mainline/v3.11-saucy/linux-headers-3.11.0-031100_3.11.0-031100.201309021735_all.deb

wget -c kernel.ubuntu.com/~kernel-ppa/mainline/v3.11-saucy/linux-headers-3.11.0-031100-generic_3.11.0-031100.201309021735_amd64.deb

wget -c kernel.ubuntu.com/~kernel-ppa/mainline/v3.11-saucy/linux-image-3.11.0-031100-generic_3.11.0-031100.201309021735_amd64.deb


8. Now it’s time to install the kernel:

sudo dpkg -i linux-headers* linux-image*

9. Reboot

Ok track-pad should be working like a champ. If you have any problem on the steps above you can pm me.


10. Now it’s time to adjust Some Synaptics Options Edit /usr/share/X11/xorg.conf.d/50-synaptics.conf by running:

sudo gedit /usr/share/X11/xorg.conf.d/50-synaptics.conf

Find the line

MatchDevicePath "/dev/input/event*"

and add these after

Option "FingerHigh" "10"
Option "FingerLow" "5"
Option "HorizHysteresis" "12"
Option "VertHysteresis" "12"



11. Save (Ctrl-O)

12. Reboot

Chromebook Hacked: Trackpad / Touchpad
Acer c7 Ubuntu 14.04 Chromebook Touchpad Fix

Thank You SO MUCH !!
Excellent fix and much appreciated after having to rely solely on an external touchpad for almost a year now.
Wish I'd come across your post even sooner.
Well done and now I'm a even a new member of this site so the mods should be thanking you as well.
Cheers !

Hey man, I'm really just a newbie but I have an idea.
At the beginning of the main post ...


************************************************** **********************
Track-pad Fix:


1. Open Terminal and gain access to root:

Sudo -s

2. Once you have login as a root user:

nano -w /etc/modules
or
sudo gedit /etc/modules
...
************************************************** ***********************

Start by entering THIS COMMAND directly into the TERMINAL.

sudo gedit /etc/modules

You'll be prompted to enter your password, THEN ...

When you enter it into the terminal make sure a TEXT EDIT FILE appears in a separate window, not just the modules list showing in the terminal.
You should then be entering the next commands specified by the post - INTO THE TEXT FILE.

3. Add the following lines in this order:

loop
lp
rtc
i2c-i801
i2c-dev
chromeos-laptop
cyapa

4. Save (Ctrl-O)

Make sure you enter them INTO THE TEXT FILE, NOT the terminal directly, then save your commands in the TEXT FILE by hitting the SAVE BUTTON.
This is what was not quite clear to me the first time I tried it.
Again, I'm NO EXPERT but try this and see if it works.
Good luck.
