Ubuntu

Touchpad stops working after some time, works again if restarted using Fn Key and F7

Asked by Fahad

Hey Everyone!

I've been running Ubuntu on my laptop for a while now. It's been working alright, but today, when I rebooted it and logged in, the touchpad stopped working after some time. I disabled the touchpad and re-enabled it using the button on my keyboard, and it started again. Problem is, the touchpad keeps shutting off automatically after some time.

I'm using Ubuntu 14.04, and the kernel version is 3.13.0-43-generic.

I'm not sure what information will be helpful, so ask for anything you need!

I'd be very glad if you could help me fix this.

Thanks in advance!

When the touchpad stops working, press CTRL + ALT + T and run:

dmesg | tail; lsb_release -a

What is the output please?

Run the below command and reboot to test:

echo "options psmouse proto=imps" | sudo tee /etc/modprobe.d/psmousefix.conf > /dev/null

Ok, you can run:

sudo rm /etc/modprobe.d/psmousefix.conf

To remove the file and reboot. I suggest you report a bug
