From today morning, The TouchPad in my IBM T410 laptop was not working.
It was very tough to work on laptop without the touchpad.
Searched in net and found a solution to make it work.
We have to unload and reload the kernel module for the touchpad.
Here are the commands to execute.
sudo rmmod psmouse
sudo modprobe psmouse
If there is no terminal window open, you can use one of the following:
In Gnome or KDE, press Alt + F2, type gnome-terminal and press Enter
Press Control + Alt + F1, login with your username and password, type the commands, then press Control + Alt + F7 to get back to X
After running the second command 4-5 times, the touchpad started to work.🙂
