Fixing dell inspiron unresponsive touchpad

I face a problem in laptop touchpad not responding while upgrading ubuntu 14.04 to 14.10 or newer versions. Touchpad was working fine in ubuntu 14.04 but when I upgrade ubuntu to 14.10 and 15.10 the touchpad seems to be unresponsive.It works perfectly on Windows and when I use a wireless mouse it works as well.

Solution 1

To solve this problem you will need to blacklist i2c-hid. To do this follow these steps:

• Open /etc/modprobe.d/blacklist.conf as super user.
• Add blacklist i2c-hid towards the end of the file.
• Save and Reboot

After reboot you can see your touchpad is working fine. If not so then try the alternate solution that is:

Alternate Solution

• Run sudo -H gedit /etc/default/grub
• In the open window edit line GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" it should look this way GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i8042.nopnp"
• Save the file and run sudo update-grub
• Run these:
• echo "blacklist i2c_hid" | sudo tee /etc/modprobe.d/i2c-hid.conf
• sudo depmod -a
• sudo update-initramfs -u
• echo "synaptics_i2c" | sudo tee -a /etc/modules
• Save and reboot.
