I am using Dell Inspiron 3521 model.
Ever since I installed ubuntu, my touchpad (Synaptic) is not working.
However an external mouse is working fine.
On running command "cat /proc/bus/input/devices" , touchpad is not being shown up!
I have tried installing all the drivers, updating the kernel and creating psmouse.conf file too (I got these solutions from internet).
Still the problem persists.
Please help me out!

good luck!
