Hi all,
Just wanted to add my experience with this. I also have found that my
Synaptics touchpad becomes unresponsive after waking from a suspend. It
isn't restored by a modprobe -r psmouse / modprobe psmouse. The only
thing that restores it is a shutdown (without -r option) followed by a
fresh boot.
I noticed also that, when it is showing this unresponsive touchpad
symptom,
sudo cat /dev/input/event8 | hexdump
produces nothing at all when i move my finger around on the touchpad
(event8 is the touchpad in my system, as shown by
/proc/bus/input/devices). Yet, doing:
sudo cat /dev/input/event16 | hexdump
(which is my usb wireless mouse) does produce output when I move my
mouse around.
I'm not very familiar with kernel, drivers, firmware, etc. I did think
the bit about /dev/input/event8 was interesting though, but I'm not sure
what to do with that information.
If anyone is interested, please feel free to suggest a set of commands
and their output you might want to see, or procedures to try. I hope
this new data point is useful.
Thanks in advance!
Henry
