@kendatsuba or anyone here who seemed to have a good understanding of these elantech issues, could you take a look at https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1166442 and maybe make some suggestions to fix it for Gigabyte users... :(

Just wanted to report that the fix from post #137 works for my Lenovo Yoga 2 11.
dmesg reported before:
[ 16.922014] input: PS/2 Elantech Touchpad as /devices/platform/i8042/serio1/input/input7
and after
[ 3990.888082] input: ETPS/2 Elantech Touchpad as /devices/platform/i8042/serio1/input/input112

thanks a bunch!
Should this somehow be reported to be included in the Ubuntu 14.04 kernel?
I updated today and have:

Also affects me on Samsung 900X3G with 14.04!
#137 did not work for me!
3+ finger gestures do not work.
I want my multitouch gestures back!

Verified that with fix in post #137, I can now use multi-touch on my Lenovo Y50 touch.

Yes, I can confirm that fix in post #137 helped me too for Lenovo Y50-70 in order to enable multi-touch. Befor that pach the touchpad was nod detected (two finger scroll not working).

Post #137 broke the right click for my Lenovo Z50. But the solution in http://superuser.com/questions/619582/right-elantech-touchpad-button-not-working-in-linux fixed it. But that solution broke the middle button emulation.
Ubuntu 14.04.1
http://superuser.com/questions/619582/right-elantech-touchpad-button-not-working-in-linux

The fix in comment #137 also fixed my touchpad being detected on my Lenovo U530, and now two-finger scrolling works!

Only problem is that now there seems to be a slight (but noticeable) input lag. Does anybody else have this issue?

I posted a question on superuser about my problem here: http://superuser.com/questions/802797/elantech-touchpad-driver-issues-and-input-lag-in-linux

I'm still having to rmmod psmouse and modprobe psmouse after every boot. Upon boot, dmesg shows this:

[ 4.929432] psmouse serio1: elantech: unknown hardware version, aborting...

But after I rmmod and modprobe dmesg reports this:

[ 1750.169375] psmouse serio1: elantech: assuming hardware version 4 (with firmware version 0x495f01)
[ 1750.179735] psmouse serio1: elantech: Synaptics capabilities query result 0x70, 0x15, 0x0e.

There is only one psmouse.ko in /lib/modules:

$ find /lib/modules -name psmouse.ko
/lib/modules/3.13.0-24-generic/updates/psmouse.ko

Sure, "locate psmouse.ko" finds the old module that dkms backed up in /var/lib/dkms/psmouse/original_module/3.13.0-24-generic/x86_64/psmouse.ko, but surely this isn't the one that's loading on boot, right? It seems something else is going on. I just wish I knew what. Thoughts?

Its not working after updating to new kernel version 3.13.0-35-generic ,new patches are available ?

Answering my own question: Turns out the old psmouse was in the initramfs so running update-initramfs -u -k all and rebooting fixed it.

Also attempting to answer lohith's question: You have re-install the driver for every new kernel until support is added upstream. Just repeat the dkms commands, and run the update-initramfs command above, and you should be good.

Regarding comment #137 and its effect, I feel it is worthwhile mentioning that the ldtarball does not work for the ElanTech touchpad within the Fujitsu Celsius H730.

There, the touchpad does not _work at all_, unlike here where multitouch features are a miss. There's bug #1300427 for that issue though, but these two seem somewhat related.

If there is any data that would be relevant to this bug, then I'd be glad to provide it.

I'm using an ASUS TP500L laptop running 14.04 with an Elantech touchpad. Xinput lists it as an "ETPS/2 Elantech Touchpad" initially and Unity settings shows me the Touchpad area. However, it is entirely unresponsive to any form of input. I have tried the fix in #137 and it changes nothing. I have tried a couple of other dkms based fixes which have the same effect as reloading the psmouse with a bare protocol, giving me a generic PS/2 mouse and no multitouch or scrolling features. Should I post any logs?

Look at the last post ... in

http://askubuntu.com/questions/529974/elantech-touchpad-not-working-at-all/541966#541966

#137 and #167 helped me on Lenovo G5070 to have multitouch working (edge scrolling, two-finger scrolling, two-finger right-click, right and middle clicks on corners). However it broke the physical right click.

I just want to report that Elantech touch-pad still not working in a new asus tp500la with bios verison 203, under ubuntu 14.04, 64bit, kernel version 3.13.0-40-generic. The touch-pad is recognized as PS/ Elanctech BUT is not working at all (no response at all) After
sudo modprobe -r psmouse
sudo modprobe psmouse proto=imps
the touch pad is recognized as PS mouse. BUT there is no touch-pad functionality, which means no scrolling, no two finger click, and most important, no deactivation during typing.

Same issue for me. Latest attempt was loading Kernel 3.18 but still inop as full feature touchpad. Can only load and use as a ps2/mouse.

Fix #137 worked for me:

Linux patterntop 3.13.0-43-generic #72-Ubuntu SMP Mon Dec 8 19:35:06 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux

Lenovo Z50-70
aka Lenovo Z50 70

Fix #137 worked for me when combined with the modification/bugfix in #161:

Linux patterntop 3.13.0-43-generic #72-Ubuntu SMP Mon Dec 8 19:35:06 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux

Lenovo Z50-70
aka Lenovo Z50 70

HOWEVER - this broke my right click exactly as described in #161. I opted to keep the broken right touch pad because the double tap seems to bring up the right click menu.

After thinking about it, I implemented the fix in the #161 link to the tar.gz file provided in #137.

This is verified working! Thanks everyone and #161 I hope you either figured this out or see this.

@Trent Robbins
Can you post the joined (#161 & #137) fix?

@ Daniel Ceregatti
had the same problem that I had to reenter rmmod/modprobe after every boot, but update-initramfs -u -k all solved it for me as well - thanks!

@Trent Robbins
Can you post the joined fix (#161 & #137) ? i'm having the same problem.

Hi there. I combined #161 with #137. Rightclick and multitouch now working on my Lenovo g50-70. Like @Trent Robbins verified, this should also fix the rightclick issue on the z50-70. You can use the dkms package from the attachment using:

sudo dkms ldtarball psmouse-elantech-x551c-G50-70.tar.gz
sudo dkms install -m psmouse -v elantech-x551c-G50-70

sudo rmmod psmouse
sudo modprobe psmouse

@dormux Are you occasionally getting an error where your mouse doesn't work and you have to rmmod psmouse / modprobe psmouse to reset the driver?

Hi. No never experienced such behaviour. I'm using the modified driver since i wrote these lines above and never had any issues.

This affects my laptop (Lenovo Yoga 3 11.6" 2-in-1):

ubuntu@ubuntu:~$ lsusb

Presumably the touchpad is the following line then:

Excerpt of /proc/bus/input/devices:

The touchscreen works fine, as well as both left and right clicks. Just the multitouch doesn't work at all.

mika, I also have the asus TP500LN and this seems to be a different problem to this bug.

Description of bug is mouse does not work at all. Dmesg gives "lost sync at byte 6" messages. Mouse does work with proto=imps parameter but no two-finger functionality. If this is the same with you, after sudo su try
echo 1 > /sys/devices/platform/i8042/serio4/reg_07
(or serioX?)
and see if it fixes the issue.

For at least asus TP500LN a kernel patch is under consideration

Many thanks to Ulrik de Bie!

Perhaps you can post on bugzilla that it affects TP500LA too.

Forgot @mika: Elantech device ETD0108

The package in comment #137 fixed the bug on a Packard Bell (Acer) EasyNote ENTG71BM.

@gmoutso, I have TP500L here, your fix returns,

"bash: /sys/devices/platform/i8042/serio4/reg_07: No such file or directory"

In fact, it seems any bash command in /sys returns the same error, No such file or directory. Any ideas?

Never mind, I had modprobed psmouse proto=imps, and fixed the issue by running the command:

sudo rmmod psmouse && sudo modprobe psmouse

My touchpad is now working with full functionality. I also found the following instructions to automate this command on boot and create scripts to run it on resume from suspend/hibernate:

To enable the Touchpad you'll need to do the following from terminal:

1. sudo nano /etc/rc.local
2. Add the following line before the exit command. (sudo bash -c 'echo 1 > /sys/devices/platform/i8042/serio4/reg_07')
3. press CTRL+O then press Enter.

this will enable the touch-pad on start-up but it might stop working when suspended and/or hibernated. a workaround for this is:

1. sudo nano /etc/pm/sleep.d/sr-enable

and copy the following to the file

#!/bin/bash

case "$1" in
    suspend)
        ;;
    resume)
       sudo bash -c 'echo 1 > /sys/devices/platform/i8042/serio4/reg_07'
        ;;
    *)
        ;;
esac

3. press CTRL+O then press Enter.

4. sudo nano /etc/pm/sleep.d/ht-enable

5. again copy this

#!/bin/bash

case "$1" in
    hibernate)
        # executed on suspend
        ;;
    thaw)
        sudo bash -c 'echo 1 > /sys/devices/platform/i8042/serio4/reg_07' # executed on resume
        ;;
    *)
        ;;
esac

6. press CTRL+O then press Enter.

7. then (sudo chmod +x /etc/pm/sleep.d/ht-enable && sudo chmod +x /etc/pm/sleep.d/sr-enable)

8. then issue the following command ( sudo update-initramfs -u -k all )

I have the same problem as arushi, my touchpad lacks multitouch. No dkms driver or kernel solved it. I also have a similar laptop regarding hardware (hp pavilion ab series) with an elantech touchpad, device is listed as ps/2 Elantech Touchpad and I have the same exact output for

dmesg | grep psmouse:
psmouse serio1: elantech: unknown hardware version, aborting...

I am on kernel 3.19 but I also tried other distros with the latest lts kernel (4.4) even in rolling releases, still no full support.

The same situation here as Arushi , I have an HP pavilion 14-ab042TX laptop.The touchpad supports basic functionalities like single click but no multitouch and two finger scroll.
I am using ubuntu 16.04 and kernel is 4.4.0-36-generic. The output of xinput is :
