Touchpad doesn't work after suspend and hibernate

I have an Acer Aspire V3 laptop with a touchpad. I avoid suspending and hibernating on this laptop, because when it wakes up from either of them, the touchpad does not work. The strange thing is that the touchpad can wake up the machine, but it won't work afterwards.

What I have tried:

sudo pm-suspend
# *wake up*
sudo modprobe -r psmouse
sudo modprobe psmouse
# Reloading this module doesn't work, neither does reloading any other mouse input module.

# Perhaps disabling the touchpad before sleep works
xinput disable 12
sudo pm-suspend
# *wake up*
xinput enable 12
# Nope, still doesn't work

sudo pm-suspend
# *wake up*
synclient TouchpadOff=$(synclient -l | grep -c 'TouchpadOff.*=.*0') # toggle
synclient TouchpadOff=$(synclient -l | grep -c 'TouchpadOff.*=.*0') # toggle again

Extra information:

• Linux 3.16.1

• Synaptics (xf86-input-synaptics) 1.8.0

• Xfce 4.10

• xinput list:

  Virtual core pointer                    	id=2	[master pointer  (3)]
  ↳ Virtual core XTEST pointer              	id=4	[slave  pointer  (2)]
  ↳ SYN1B7E:01 06CB:2970 UNKNOWN            	id=12	[slave  pointer  (2)]

Does anyone know how to solve this?

Re: Touchpad doesn't work after suspend and hibernate

No, I haven't. Today I tried a full-system upgrade, (including upgrading the kernel to 3.17.2), and everything seems to be working fine now. The touchpad works after suspend and hibernate. So, thanks.
