Now you need to configure your kernel. You can start with the configuration of the kernel you're running:
$ cd ubuntu-precise/
$ cp /boot/config-$(uname -r) .config
$ make oldconfig
NOW you can build your kernel using that configuration (note the -j8 compiles with 8 threads. It'll max your cores):
$ make -j8
(this took me about 45 minutes; grab some lunch).

TEST NEW DRIVER
--------------------------
The touchpad driver is compiled as a kernel module, which makes it super easy to test. First, get to where the module was compiled:
$ cd ubuntu-precise/drivers/input/mouse/
Stop using the installed module for your touchpad (note that your touchpad will stop working):
$ sudo rmmod psmouse
Give your newly compiled module a test run:
$ sudo insmod psmouse.ko
First of all, your mouse should be working again. Second, while you should be able to tap-to-click everywhere on the touchpad if tap-to-click is enabled, if tap-to-click is DISabled you shouldn't be able to tap-to-click anywhere, including the mouse button zones (although do take note of comments 2-3).
To stop testing the newly compiled module, unload it and load up the system version instead:
$ sudo rmmode psmouse
$ sudo modprobe psmouse
Note: If you reboot, the system version of the module will be loaded on boot.
To apply the patch:
------- ------- ------- ------- ------- ------- ------- ------- -------
APPLY SOURCE CHANGES
-------
Clone Kamal's kernel (this is the one used by the Sputnik Ubuntu release):
$ git clone git://kernel. ubuntu. com/kamal/ ubuntu- precise. git
(That may take some time).
Download and save the patch from comment #1.
Patch the kernel git repo you just checked out:
$ cd ubuntu-precise/
$ git am <path-to-patch>
Check to make sure it succeeded:
$ git status
Make sure that mentions that you're ahead of the master by 1 commit.
