This bug is marked incomplete. Does that mean that I didn't provide enough information?

I have been tinkering with the drivers for this hardware and I believe this bug should be moved to kernel, as per https://wiki.ubuntu.com/DebuggingTouchpadDetection.

The Samsung QX410 uses an Elantech trackpad. The psmouse driver includes support for some Elantech pads, but this particular one isn't recognized because it returns a different result when queried via the "magic knock" (function elantech_detect in elantech.c). This happens before the force_elantech module parameter comes into effect (which forces use of elantech when the firmware version is not recognized, but AFTER the magic knock has returned the expected result).

I forced the elantech driver to continue initializing the pad despite the unexpected reply to magic knock, and this is what I got (dmesg output):

[ 9721.216300] elantech: unexpected magic knock result 0x3c, 0x03, 0x00.
[ 9721.250065] elantech: Elantech version query result 0x85, 0x1b, 0x00.
[ 9721.284321] elantech: assuming hardware version 2, firmware version 133.27.0
[ 9721.318037] elantech: Synaptics capabilities query result 0x19, 0x14, 0x0c.
[ 9721.578902] elantech: retrying ps2 command 0xe6 (2).
[ 9722.094936] elantech: retrying ps2 command 0xf8 (2).
[ 9722.797061] elantech: retrying ps2 command 0xf8 (1).

If the system is rebooted with the modified psmouse driver, the device gets properly reported as a touchpad and all the relevant controls appear in the mouse control panel. However since data received from the pad is apparently not decoded properly by the psmouse driver (different encoding schema maybe), nothing really works: there's no pointer movement and the only thing that generates events (as read by evtest) are the left and right buttons (and then, not consistently).

I'm attaching output from evtest (keep in mind I was sliding my finger across the pad and clicking buttons, all that registers are the button clicks) and from dmesg, showing loss of sync and subsequent reconnection from the driver.

I hope this helps with this bug, I guess a lot of newer computers will start using these newer Elantech pads and it'd be great to have support out of the box.

The modified psmouse driver gives the following output in /proc/bus/input/devices (only the section relevant to the touchpad):

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/input23
U: Uniq=
H: Handlers=mouse0 event8
B: EV=b
B: KEY=6420 30000 0 0 0 0
B: ABS=f0003

Do keep in mind that, though with this little hack I managed to get the touchpad recognized, it's not functioning at all (no pointer functionality).

I believe this bug also affects the new Samsung NF210. Should I dump the apport-collect output here, or open a new bug?

I don't think you need to do the whole apport-collect. Just attach a file with dmesg output.

/var/log/dmesg from Samsung NF210

Please update the summary to include the Samsung RF710 as well. (17inch model)

Since this is a hardware detection issue, shouldn't it be reassigned to kernel so that the right people see it? Who can do that? It doesn't seem to me that this has anything to do with xorg-video-intel.

For my NF210, I also tested against Fedora kernel to determine if this was an Ubuntu thing or a more general kernel problem. Same issue. So I reported to bugzilla.kernel.org. Feel free to add comments to that bug if you have the same problem.

https://bugzilla.kernel.org/show_bug.cgi?id=27442

I too have a samsung nf-210 and am also affected by this bug. This is indeed a kernel bug and not related to xserver-xorg-video-intel :)
Most likely the new protocol has to be reversed so a new patch for the psmouse driver can be written. Is there actually anyone working on this bug atm?

I have a rf710, too, and recently filed a bug because of the touchpad not working...

https://bugs.launchpad.net/ubuntu/+source/linux/+bug/683092

the same stuff happens in a rf410 14 inch model

The same problem here at my samsung NF210 HZ1 :-(

I got the same with samsung rf510

This is now assigned to kernel, so I suspect it will get more attention if
the comments also go into the linked kernel bug. Nobody seems to be
looking here any more.

#113 just worked for me on a Samsung NF210 =) thank you very much, this wasn't for me, it was for my younger sister. She will be happy. =)

I have the issue on the Acer 7560, will try comment 64 patch and report back.

Tried patch 64 on my 2.6.38-10-generic, worked beautiful. Shame that there aren't any 3-button, rotation, pinch gestures as of yet.

Patch 59 seems working perfect on my Asus K43SV Natty 2.6.38-10-generic :)
Thx

Tried patch from #113 on 2.6.38.11-generic on my Samsung RC512 and it gives me two-finger scrolling (finally!), a two-finger tap anywhere on touchpad will bring up the right-click menu, and double-tap-and-drag. As noted above, there is a bit of wobble. If there is middle-click emulation in this patch, I'm not able to do it.

I've posted an update to the driver, this time just as a dkms package. It's avaiable at

http://people.canonical.com/~sforshee/lp681904/psmouse-elantech-dkms/v0.1/psmouse-elantech-dkms_0.1_all.deb

Please test and let me know how it works. Thanks!

Hi Seth,

Thanks so much for the deb for the dkms driver. Super-easy to install:

wget -c http://people.canonical.com/~sforshee/lp681904/psmouse-elantech-dkms/v0.1/psmouse-elantech-dkms_0.1_all.deb

sudo dpkg --install psmouse-elantech-dkms_0.1_all.deb

I simply rmmoded the old psmouse driver, then modprobed the old one on the fly and things started working. . Mouse pointer functionality, two finger scroll and double-tap-for-right-click are what I tested, all seem to work just as with the previous patch (I was using the dkms version of the elantech-v6 patch).

This is on Natty with a just-installed 2.6.38-11 kernel, running on a Samsung QX410.

My dmesg reads:

[ 148.846439] elantech: assuming hardware version 3, firmware version 133.27.0
[ 148.880705] elantech: Synaptics capabilities query result 0x19, 0x14, 0x0c.

[ 148.972206] input: ETPS/2 Elantech Touchpad as /devices/platform/i8042/serio1/input/input13

Let me know if you need more information.

Thanks again!

Just installed it. It is working nicely. Any wobbling is indeed entirely
gone now.

The update works great on my Samsung RC512 running Linux 2.6.38.11-generic.
Wobble is essentially gone.
Here is some of the output of dmesg:

I just installed http://people.canonical.com/~sforshee/lp681904/psmouse-elantech-dkms/v0.1/psmouse-elantech-dkms_0.1_all.deb (#123)
On my Samsung netbook NF210.

It didn't work for me and now trackpad is not responding. I am new to Linux may it be some missing settings?
I just used Package installer on it and then restarted.

Thanks.

After install the .deb package from Seth,

sudo rmmod psmouse
sudo modprobe -a psmouse

you should get the following in dmesg

dmesg | grep elantech

Thanks Zaki.
However after
sudo rmmod psmouse

It gave me an error. Module psmouse does not exist in /proc/modules

I understand this isn't a board for me to raise more questions but I could really use some help on this, since my pad isn't working now.
Thanks a lot.

I just tried the DKMS in post 123 on an nf210

uname -a yields...

Linux elara 2.6.38-10-generic #46-Ubuntu SMP Tue Jun 28 15:05:41 UTC 2011 i686 i686 i386 GNU/Linux

The module won't load. modprobe gives...

FATAL: Error inserting psmouse (/lib/modules/2.6.38-10-generic/updates/dkms/psmouse.ko): Unknown symbol in module, or unknown parameter (see dmesg)

bottom lines of dmesg are...

[92650.108872] psmouse: Unknown symbol hgpk_module_init (err 0)
[92650.111041] psmouse: Unknown symbol hgpk_init (err 0)
[92650.115138] psmouse: Unknown symbol hgpk_detect (err 0)

Thanks Eric.

Could you please post how to revert back so I could use the trackpad again haha

I just saw there's a release that works with nf210 hopefully in post #113 but couldn't get it started either. Looks like I need to fix the trackpad first.

Thanks in advance.

himegoto: First, please run 'sudo modprobe psmouse' (which I'm expecting will fail), then 'dmesg > dmesg-psmouse-elantech-dkms.txt'. Please provide the output from modprobe and the dmesg-psmouse-elantech-dkms.txt file here. After that you can remove the package by running 'sudo dpkg -r psmouse-elantech-dkms'. Then running 'sudo modprobe psmouse' should get your touchpad working again.

EricDP: Your problem is due to configuration differences between i386 and amd64 kernels in conjunction with how I created the dkms package. I've uploaded a new package which should fix this. Please give it a try.

http://people.canonical.com/~sforshee/lp681904/psmouse-elantech-dkms/v0.2/psmouse-elantech-dkms_0.2_all.deb

Hi Seth, thanks for your support with this. I have a Samsung SF310 and am running ubuntu natty (whatever the default kernel is). I have installed your patch from post #123. Most things work but I cant click and drag with 2 fingers (i.e. click left mouse button and drag with the other finger). is this a known issue or is it supposed to work? It was working fine with the patch from post #63 but its no longer working correctly. Can you advise on what I need to do?

p.s. I did sudo rmmod psmouse
sudo modprobe -a psmouse

after installing the package if that makes any difference.

Thanks

Seth, many thanks I could use the pad again.
However I couldn't find the txt.
I saved all the commands from "dmesg", will that be useful to you? It's huge lines of commands.

Thanks.

v0.2 seems to be working on my nf210 with the 32-bit fix. I didn't test everything, but being able to disable tap-to-click and have two-finger scroll working is good enough for me. And having a DKMS package so I'm not building from scratch is a definite bonus. Thanks!

Seth,
I tried the 0.2 you gave in #132
The side scrolls now works but 2 finger scroll didn't.

If this'll be useful to you :)
Thanks.

The 0.2 from #132 now allows me to scroll horizontally but I can't disable tap-to-click (Samsung RC512).
Output from dmesg:

I applied the patch at comment 64 to my Samsung NC210 netbook running 64 bit Ubuntu 11.04 (kernel 2.6.38.11) and after a reboot the touchpad is recognised (previously it had been detected as a psmouse. Mouse preferences now has a touchpad tab which allows me to turn off mouse-clicks on the touchpad, and activate two finger scrolling. This is fine for me.

@Seth: Patch from #132 working fine for me.
running Xubuntu 11.04 with 2.6.38-11-generic on a Samsung RC710.

For drag-and-drop, two finger right click, and three finger center click I had to set Synaptics Tap Action to 0, 0, 1, 1, 1, 3, 2.

(If somebody is looking for it:
xinput list
Should show you a device ETPS/2 Elantech Touchpad. Look for its ID. Then set
xinput set-int-prop <ID> 292 8 0 0 1 1 1 3 2

You can take a look at the properties with xinput list-props <ID> if the Property ID changes (in this case the 292). )

After installing Linux Kernel 3.0.4, the wobble has returned and I still can't enable middle click, disable tapping, or disable touchpad while typing.

Patch on post 132 worked perfectly for me. Trackpad, two-finger touch for right click and two-finger scroll function as they should.

It'd be nice to see some support from elantech on this, though, to get the full range of features working properly. It really is a cool trackpad... even though I'd kill for a regular synaptics after this enormous hassle getting it working.

I have just upgraded to oneiric and I am still unable to properly use my trackpad. Here are some details:

Craig: We have some successful testing with the QX410, but it appears
that there may be more than one variant of this model. Please open a new
bug for your issue by running 'ubuntu-bug linux' in a terminal. Thanks!

Thanks Seth. Created related bug #875154 for this issue.

upgraded to oneiric but I still cant click and drag with 2 fingers?? anyone else have this? or is just me? everything else seems to work

Samsung SF310 by the way

I noticed that touchpad features like two finger right click, two finger scrolling work fine on QX510 after fresh install of Oneric.

I've noticed very similar symptoms on a Samsung 700Z laptop with an elantech touchpad. I think it might be a newer model number than is found in this driver? I created a bug #894515 to track this.

Hi all,

I'm on Ubuntu 10.10 with custom compiled kernel (Linux Menetius 3.1.4 #1 SMP PREEMPT Fri Dec 9 18:09:45 CET 2011 x86_64 GNU/Linux)

I'm quite a newbie so plz don't shoot me asking this question: how can I apply this kernel patch?

I mean...I've downloaded kernel 3.1 from kernel.org...then? before compiling how can I apply it?

Thx in advance to whoever will reply!!

I have a QX 410 running ubuntu 11.04 and the trackpad issue is as follows. The Elantec Trackpad or "Magicpad" is misdetected as a generic ps2 mouse so scroll functions aer not available also Trackpad doesn't disable while typing! I hav also tried installing the new Ubuntu 11.10 and the problem is worse in 11.10 the left and right trackpad button both do a left click so context menus and right click options don't work either!

Please file a new bug for your issue by running 'ubuntu-bug linux' in a
terminal. Thanks!

thanks for helping me detect my mouse.
Here are my xinput, lspci, dmesg, here is what i'm now unsure of, how do I get the touchpad window under mouse options so I can set two finger scrolling or other multitouch functions. when I try synclient, I get the following error.

This bug has been reported on the Ubuntu laptop testing tracker.

A list of all reports related to this bug can be found here:
http://laptop.qa.ubuntu.com/qatracker/reports/bugs/681904

This driver is broken on official kernel 3.8. In linux/drivers/input/mouse/input-mt.c:
function input_mt_init_slots now requires 3 args, with the new arg being flags. I set flags to 0 in synaptics.c:699 in this patch and it re-compiled fine. I have no clue as to what that will break, but I saw in the mainline kernel synaptics.c that's what it was set to.

/**
 * input_mt_init_slots() - initialize MT input slots
 * @dev: input device supporting MT events and finger tracking
 * @num_slots: number of slots used by the device
 * @flags: mt tasks to handle in core
 *
 * This function allocates all necessary memory for MT slot handling
 * in the input device, prepares the ABS_MT_SLOT and
 * ABS_MT_TRACKING_ID events for use and sets up appropriate buffers.
 * Depending on the flags set, it also performs pointer emulation and
 * frame synchronization.
 *
 * May be called repeatedly. Returns -EINVAL if attempting to
 * reinitialize with a different number of slots.
 */
int input_mt_init_slots(struct input_dev *dev, unsigned int num_slots,
                        unsigned int flags)

My specs are: Samsung Series 7 Ultrabook 730U3E, Ubuntu Raring Ringtail 13.04 (development branch), Kernel 3.8.0-15.

I can confirm this bug in raring. Synclient can't find synaptics properties and there is no touchpad-tab in mouse settings gui.

Two-finger-scrolling, edge-scrolling and multi-touch stuff is not working. Left and right buttons are working, though.

I'm very interested in comment #154 by nik.martin. I've understood that I should assign a 0 as the missing arg, but I'm not sure about how to do it in practice.

Line 699 looks like this now:
  input_mt_init_slots(dev, 2);
Should I change it to something like the following?
  input_mt_init_slots(dev, 2, 0);

Thanks a lot for any help
