Title:
FocalTech touchpad stops working after suspend
Status in linux package in Ubuntu:
Incomplete
Bug description:
I have an Asus V502LX the persian version of the Asus K501LX.
I have Ubuntu 14.04 installed and the kernel 4.1.6 installed. I had to
install the kernel 4.1.6 to have the touchpad recognised. Under kernel
3.19.30, as I am running now to file in this bug, the touchpad is
recognised as a simple mouse (no two fingers scrolling...) and the
problem I am describing below is also present...
I noticed one problem. The Focaltech touchpad is not working after
suspending the computer.
Here is what I could find about the touchpad in
/proc/bus/input/devices
I: Bus=0011 Vendor=0002 Product=0012 Version=0000
N: Name="FocalTechPS/2 FocalTech FocalTech Touchpad"
P: Phys=isa0060/serio1/input0
S: Sysfs=/devices/platform/i8042/serio1/input/input5
U: Uniq=
H: Handlers=mouse0 event4
B: PROP=5
B: EV=b
B: KEY=e520 10000 0 0 0 0
B: ABS=260800000000003
Before suspending the computer, I can deactivate and activate again
the touchpad with the hotkey of my keyboard without problem. However,
once the computer suspended, nothing work to re-activate the touchpad.
I tried a solution given on internet but it doesn't work properly.
I created a file here /etc/pm/sleep.d/0000trackpad
sudo gedit /etc/pm/sleep.d/0000trackpad
and add the following
#!/bin/sh
case "$1" in
suspend|hibernate)
modprobe -r psmouse;
resume|thaw)
modprobe psmouse;
esac
With this file, the computer refuse to suspend. The touchpad keep
working so it does something but I can't make my computer sleeping...
