Touchpad not working after suspend

Fuxino · 2015-11-12 13:27:25

I have tried the suggestions in the wiki but they didn't work. The only thing I can do is reboot.

Running synclient gives this:

$ synclient TouchpadOff=0
Unable to find a synaptics device.

Any ideas? Tell me if you need more informations

I'm not sure if this is useful, but I've discovered this. The output of "cat /proc/bus/input/devices" returns:

$ cat /proc/bus/input/devices
...
I: Bus=0011 Vendor=0002 Product=000e Version=0000
N: Name="ETPS/2 Elantech Touchpad"
P: Phys=isa0060/serio1/input0
S: Sysfs=/devices/platform/i8042/serio1/input/input11
U: Uniq=

B: PROP=5
B: EV=b
B: KEY=e420 10000 0 0 0 0
B: ABS=661800011000003
...

but when I suspend and then resume, that part isn't there.

could it be something in your bios? And, how are you suspending? Are you using systemctl?

I'm not sure about the bios/firmware, but I don't recall any relevant option in there.

And, how are you suspending? Are you using systemctl?

systemctl suspend or simply closing the laptop lid, it makes no difference.

Also, I'm using linux-grsec kernel, but I've tried both the standard linux and linux-lts and it's the same.

Does it work again, if you rmmod and modprobe the touchpad driver? If so, you could use a script as a workaround, that does this on wakeup.

No, I already tried that as suggested in the wiki, but it doesn't work.

This is still not solved

I've found that when I resume I get this error in Xorg log:

(EE) ETPS/2 Elantech Touchpad: Read error 19
