I've been trying to figure out how I can make my touchpad work after waking up from suspend.

Until recently I could at least reactivate it by typing:

ls /lib/modules/`uname -r`/kernel/drivers/input/mouse
sudo modprobe -v synaptics_i2c

(btw how can I actually determine which driver is handling my touchpad? lspci -k isn't helping me and I'm fairly new to linux?)

A recent kernel update caused this method to not work anymore. I've found this solution, but it doesn't work

sudo touch /etc/pm/sleep.d/0000trackpad
sudo gedit /etc/pm/sleep.d/0000trackpad

and paste in the following:

case "$1" in
         modprobe -r psmouse ;;
        modprobe psmouse ;;

Finally, making it executable:

sudo chmod +x /etc/pm/sleep.d/0000trackpad

How can I get my touchpad to work after waking from suspend?

  • Hi and welcome to unix.SE. A better way to format your question as code is to indent code blocks by four spaces. See the edits I've made to your question. – drs May 21 '14 at 23:07
  • Your question about determining which driver is handling your touchpad should be asked as a separate question. That way it's more which answers are for which questions (and people have an easier time finding that answer when searching in the future). – drs May 21 '14 at 23:10
  • Are you sure the first line in your old method is correct? ls /lib/modules/`uname -r`/kernel/drivers/input/mouse will only print out that file path (expanding uname -r). It doesn't change anything in the system... – drs May 21 '14 at 23:12

I would simply try disabling/enabling it via xinput instead. You can do this by acquiring the devices id=# from the xinput command.

$ xinput --list | grep TouchPad
⎜   ↳ SynPS/2 Synaptics TouchPad                id=12   [slave  pointer  (2)]

You can parse the id= using this command:

$ TID=$(xinput list | grep -iPo 'touchpad.*id=\K\d+')

And then disable/enable it:

$ xinput disable "$TID"
$ xinput enable "$TID"
  • I have this problem and my touchpad is not listed when I type $ xinput. There is only the XTEST virtual pointer and my ELAN touchscreen. – Robbie Wxyz Oct 31 '14 at 19:42
  • Ask a new Q on the site. Reference this Q&A saying that it doesn't work for your particular situation, see if someone can help. – slm Oct 31 '14 at 19:51
