Comment 81 for bug 1791427

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
