I recently installed Mint 17 on my recently bought laptop, messing with the menus I noticed no options under the Touchpad tab on Mouse and Touchpad work, so I can't disable the touchpad while typing or mess with any touchpad related configuration. That led me to conclude Mint thinks my touchpad is a generic mouse. Is there any way I can force Mint to properly recognize the touchpad? I even tried sudo modprobe -r psmouse, as suggested on another question, no success though.

Running xinput returns this:

telmo@Telmo-LT ~ $ xinput

I was able to fix the issue by updating my kernel to 3.17.1-031701. Before doing it, though, you might want to check your own kernel version by using uname -a.

For 32-bit systems:

$ wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.17.1-utopic/linux-headers-3.17.1-031701_3.17.1-031701.201410150735_all.deb

$ wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.17.1-utopic/linux-headers-3.17.1-031701-generic_3.17.1-031701.201410150735_i386.deb

$ wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.17.1-utopic/linux-image-3.17.1-031701-generic_3.17.1-031701.201410150735_i386.deb

$ sudo dpkg -i linux-headers-3.17.1*.deb linux-image-3.17.1*.deb

sudo reboot

For 64-bit systems:

$ wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.17.1-utopic/linux-headers-3.17.1-031701_3.17.1-031701.201410150735_all.deb

$ wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.17.1-utopic/linux-headers-3.17.1-031701-generic_3.17.1-031701.201410150735_amd64.deb

$ wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.17.1-utopic/linux-image-3.17.1-031701-generic_3.17.1-031701.201410150735_amd64.deb

$ sudo dpkg -i linux-headers-3.17.1*.deb linux-image-3.17.1*.deb

sudo reboot
