[Bug 1386802] Re: Synaptics touchpad is not detected on Ubuntu 14.04.1 LTS (64bit)


I've the same laptop and I make it work by using the following flag in /etc/default/grub

This post gave me the solution: 

After that you have to recreate the boot grub entry (I'm on ArchLinux: grub-mkconfig -o /boot/grub/grub.cfg. I think that in Ubuntu the command is "update-grub").
Then reboot and you will have a fully functional trackpad (mine it is detected by xorg as "SynPS/2 Synaptics TouchPad").
