now i'm using kernel 4.2 for Ubuntu 14.04 with the patch. i changed the DMI_PRODUCT_NAME with K501LX (because that is my laptop model).
I tried directly with kernel 4.2 because before that, kernel 3.19 and so, they need a driver for my touchpad. I followed the instruction here to obtain the source of kernel 4.2 for Ubuntu 14.04, https://wiki.ubuntu.com/Kernel/Dev/KernelGitGuide
git clone git://kernel.ubuntu.com/ubuntu/ubuntu-trusty.git
then from inside the folder you've just downloaded (cd ubuntu-trusty)
git tag -l Ubuntu-*
to know what is available for ubuntu 14.04
and then
git checkout -f -b temp Ubuntu-lts-4.2.0-6.6_14.04.1.1
After, to build the kernel, I followed this explanation, https://wiki.ubuntu.com/Kernel/BuildYourOwnKernel
fakeroot debian/rules clean
fakeroot debian/rules binary-headers binary-generic
then
cd ..
ls *.deb
linux-cloud-tools-4.2.0-6-generic_4.2.0-6.6~14.04.1.1_amd64.deb
linux-headers-4.2.0-6_4.2.0-6.6~14.04.1.1_all.deb

linux-tools-4.2.0-6-generic_4.2.0-6.6~14.04.1.1_amd64.deb
I deleted this two files because I don't need them
linux-cloud-tools-4.2.0-6-generic_4.2.0-6.6~14.04.1.1_amd64.deb
linux-tools-4.2.0-6-generic_4.2.0-6.6~14.04.1.1_amd64.deb
and finally,
sudo dpkg -i linux*4.2.0-6.6~14.04.1.1*.deb
sudo reboot
Now it works nicely. The touchpad works fine, without the need to install any driver and I can suspend the activity of my computer and resume without loosing the touchpad. I hope the patch will be integrated soon and I won't loose my touchpad again with updates in the future.
Thanks to Harris Anggara (harrisanggara) and Daniel Drake (dsdrake) here, https:/ /bugs.launchpad .net/ubuntu/ +source/ linux/+ bug/1490130 , I could solve my problem by adding this patch to the kernel : /marc.info/ ?l=linux- input&m= 144312209020616 &w=2
