I am running Ubuntu 13.10 64bit on my Lenovo G500 laptop. I was facing a strange problem. Whenever my laptop went to the suspended state and I resumed it afterwards, its touchpad was not working. A little bit of Googling returned a simple solution that worked like a charm. I am summarizing that solution here in this post for future reference of me and anyone else facing a similar problem.
Open up the terminal and type following command:
|
1 |
sudo -i gedit /etc/pm/sleep.d/0000trackpad |
It will create a new file named “0000trackpad” in the /etc/pm/sleep.d/ directory and subsequently open it for editing in gedit. Paste following code snippet in this window, save the file and close it.
|
1 2 3 4 5 6 7 |
#!/bin/sh case "$1" in suspend|hibernate) modprobe -r psmouse ;; resume|thaw) modprobe psmouse ;; esac |
Back to the terminal, type following command to make the newly created file executable:
|
1 |
sudo chmod +x /etc/pm/sleep.d/0000trackpad |
And … that’s it. Above steps solved the problem for me and hopefully will do the same for you too. Suspend/Resume your laptop a few times to make sure that your touchpad no longer gets disabled automatically.
