Hello,
I have a problem with my Acer Aspire Timeline 4810T, there is a small button to lock the touchpad and if I use it it will lock the touchpad but then I can't unlock it, I have to run the following line in a terminal to make it work again.
Code:
sudo modprobe -r psmouse && sudo modprobe psmouse
I'm not an expert but I think it unmounts (is it the correct term ?) the touchpad module.
I tried to find a solution and managed to add a new key shortcut that runs this script:
Code:
#!/bin/bash
  str=$(synclient -l | grep TouchpadOff | awk '{ print $3 }')
      if [ "$str" = '0' ]; then
          synclient TouchpadOff=1 &&exec 3> >(zenity --notification --listen --window-icon="/usr/share/pixmaps/touchpad.png") && echo "message:Touchpad Off" >&3
      elif [ "$str" = '2' ]; then
          synclient TouchpadOff=0 &&exec 3> >(zenity --notification --listen --window-icon="/usr/share/pixmaps/touchpad.png") && echo "message:Touchpad On" >&3
      elif [ "$str" = '1' ]; then
          synclient TouchpadOff=0 &&exec 3> >(zenity --notification --listen --window-icon="/usr/share/pixmaps/touchpad.png") && echo "message:Touchpad On" >&3
      else
          zenity --info --title="Toggle TouchPad" --text="Couldn't get touchpad status from synclient\nLaunch \"synclient -l\" in terminal to check the error" && exit 1
  fi
  exit 0
It seems to work with the touchpad lock key as the notification displays correctly but I still cannot unlock the touchpad after... I think that the button still unmount the touchpad module (as I have to mount it again with modprobe) and at the same time execute the script...

So does somebody know how to change the settings of specific key ?

Thanks
Hope you'll understand me, english is not my first language
