touchpad doesn't work after resume from suspend to ram

**pier_andreit** · 12-Aug-2015, 01:39

on my sony vaio VPCEH2N1E, RAM=4Gb, GPU=intel, CPU=intel i5 @2.4GHz, OS=opensuse 13.2, KDE=4.14.9
after boot the touchpad works well, but, after resume from suspend to ram it stops to works and I have to use an USB mouse to work.
any suggestion to have my touchpad working also after resume??
manythanks, ciao :-) pier

Hi Pier

More information about your touchpad would be useful here as it is hardware-specific.

Anyway, have a read of this thread (post #7 onwards)

https://forums.opensuse.org/showthre...-after-suspend

Let us know how you get on.

ok, many thanks deano, :-)
I read the thread https://forums.opensuse.org/showthre...-after-suspend
I rebooted only with touchpad, no other mices connected, touchpad works

hwinfo gives this as superuser:

so I supposed it was this:

Code:

 Model: "AlpsPS/2 ALPS DualPoint TouchPad"

where this:

Code:

/dev/input/by-path/platform-i8042-serio-1-mouse

was very similar to what you suggest in the thread
so I suspended to RAM and resumed (with not working touchpad) and did this as root and as user:

Code:

echo -n rescan > /sys/devices/platform/i8042/serio1/drvct

but nothing works and result was this

Code:

linux-eros1:/home/eros # echo -n rescan > /sys/devices/platform/i8042/serio1/drvct
bash: /sys/devices/platform/i8042/serio1/drvct: Permesso negato
(permesso negato means access denied)

continuing to read the thread I supposed it was the module i2c_hic
then I tried this as root before to suspend to ram

Code:

/sbin/modprobe -r i2c_hid

and then this after resumed

Code:

/sbin/modprobe i2c_hid

but nothing works.
...manythanks again, :-) other suggestion??

**deano_ferrari** · 12-Aug-2015, 15:13

Based on advice in this fedoraforum thread you could try invoking the following manually (following a resume)

Code:

device=`xinput list | sed -n '/TouchPad/s/^.*id=\([0-9]\+\).*$/\1/p'`; xinput disable $device; xinput enable $device

which just disables and re-enables the touchpad device.

If that works, it could be automated via a custom systemd resume service

https://wiki.archlinux.org/index.php...nt#Sleep_hooks

**pier_andreit** · 13-Aug-2015, 05:18

ok, with working touchpad the command as user:

Code:

device=`xinput list | sed -n '/TouchPad/s/^.*id=\([0-9]\+\).*$/\1/p'`; xinput disable $device; xinput enable $device

works, with no errors.
after resume, with non working touchpad,

Code:

procuste@linux-eros1:~> device=`xinput list | sed -n '/TouchPad/s/^.*id=\([0-9]\+\).*$/\1/p'`; xinput disable $device; xinput enable $device
Errore di segmentazione
Errore di segmentazione
procuste@linux-eros1:~> 
(Errore di segmentazione means segmentation error)

it gives this error as user and as superuser

if it can help I noted that after resume the hwinfo --mouse change in this way:
and the touchpad disappear

The device is not reinitialised, and this is probably due to the i8042 controller. You may need to examine kernel messages related to the i8042 controller to find out more about the (mis)behaviour. If you have a systemd journal, you can examine this via the 'journalctl' command, or if rsyslogd is still in use then examine /var/log/messages.

This may provide some useful output

Code:

dmesg|grep i8042

For reference, I get

Code:

# dmesg|grep i8042

Some general advice here that may be worth trying
https://wiki.archlinux.org/index.php...nate.2Fsuspend

It may be that a bug report is required to help resolve this.

if it can help,:
if I login with a new user (two users active) I have working touchpad only in the new user, and if logout with the non working touchpad user then login again I have a working touchpad.
