[arrandale] Samsung QX310/QX410/QX510/SF310/SF410/SF510/NF210/RF410/RF510/RF511/RF710 trackpad/touchpad not recognized

[Tristan Davies]

Ubuntu 10.10, Samsung NP-QX410. Trackpad settings not available. Can use trackpad, can use left and right click, but no options available to adjust settings. Personally having issue of rubbing trackpad while I type and it is very annoying.

The trackpad is recognized as a "PS/2 Logitech Wheel Mouse". No side scrolling, no disabling tap-to-click (annoying!) and no other trackpad settings available.

How to reproduce:
1) install ubuntu on a samsung qx410
2) try, try, try and fail to make the touchpad work properly

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

[Daniel Manrique (roadmr)]

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.

[Daniel Manrique (roadmr)]

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).

[EricDP (eric-arcticbears)]

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

[Stanislav (shisoik)]

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

[EricDP (eric-arcticbears)]

/var/log/dmesg from Samsung NF210

[matthew.payne (matthew-b-payne)]

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

[EricDP (eric-arcticbears)]

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.

[EricDP (eric-arcticbears)]

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

[s0ullight (s0ullight)]

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?

[marth3r (marth3r)]

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

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.

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

[Nate Cox (akujin)]

Confirmed on a Samsung RF510. Wish I'd seen this bug before buying the laptop... not having basic scroll capabilities is really, really irritating.

[f_padia (f-padia)]

Confirmed on SF310 too. not having scrolling ability is very annoying. I found a possible workaround here: http://www.voria.org/forum/viewtopic.php?f=4&t=694 but I didnt work. I didnt have xorg.conf in /etc/X11 so I created it and put the relevant stuff in it. but then when I rebooted my laptop kept going directly to tty2 and wouldnt start X. anyone know why this would happen?

[EricDP (eric-arcticbears)]

The workaround at http://www.voria.org/forum/viewtopic.php?f=4&t=694 only works on the R540 and related machines, which have a different trackpad from the ones listed in this bug. It doesn't work because the elantech driver isn't compatible with this trackpad.

[f_padia (f-padia)]

so then cant we use the same method but use another driver that is compatible with our touchpad? or is there literally no driver that is compatible with our touchpad?

[EricDP (eric-arcticbears)]

Apparently, there is no compatible driver. I've tried manually loading every driver and none detect it. You can see in the comments above that Daniel Manrique was able to modify the Elantech driver's detection to get it to detect the touchpad, but the protocol is different so it didn't work. Nobody seems to know how to fix it. :(

[Neoprenanzug (raketenforscher)]

Confirming this bug for Samsung NF210 on Lucid Lynx. Natty backport kernel alone doesnt't help.

[f_padia (f-padia)]

woohoo its been assigned! I'm willing to test and help in anyway possible on Samsung SF310.

[Vladimir Skvortsov (vskvortsoff)]

Please update the summary to include the Samsung RF410 as well.

[Mark A. Stratman (stratman)]

chin, Maria Sophie ... are you working on this?

(If not, can you please unassign yourself).
Otherwise, any progress on getting the touchpad into absolute mode? Or anything else to share?

This touchpad seems to send some really wonky stuff - which appears quite unlike what the version 1 and version 2 code is expecting. It also has a seemingly abnormal firmware version which makes me suspect that it's possibly being read incorrectly.

I might take another stab at this soon, but at this point i'm kind of prodding in the dark.

[Kevin Smith (ubuntu-qualitycode)]

This seems to be a problem with my Samsung NF310 also. I will post to the kernel bug as well.

[Rodolfo Rodrigues (rodolfo-enq)]

It affects me too. I use Maverick on my Samsung SF410.

[Mark A. Stratman (stratman)]

Tom Lin wrote a patch that gets the touchpad recognized on at least the QX410 (other models not yet tried). It's still a work in progress, but I recommend people give it a try. More info on the kernel bug thread:

Hey Tristiano77,

Thanks for your interest in Ubuntu.

Thanks for testing maverick during its development period. Unfortunately it looks like this bug report didn't get attention during the maverick development period. But I see there's not been more comments on the bug since the release, which makes me wonder if this is still an issue for you?

If you've not seen this issue since maverick's release yourself, it may have been solved by kernel or X or other updates that occurred late in the release; if so, would you mind please closing the bug for us? Go to the URL mentioned in this bug report, click the yellow icon(s) in the status column and set to 'Fix Released'.

If you no longer have the hardware needed to reproduce the problem, or otherwise feel the bug no longer needs tracked in Launchpad, you can set the status to 'Invalid'.

If you are the original reporter and still have this issue, just reply to this email saying so. (Or set the bug status to Confirmed.) If you are able to re-test this against 11.04 Natty Narwhal (our current development focus) and find the issue still affects Natty, please also run 'apport-collect <bug-number>' while running natty, which will add fresh logs and debug data, and flag it for the Ubuntu-X development team to look at.

[Daniel Manrique (roadmr)]

I'm marking this bug as invalid for xserver-xorg-video-intel, as the bug (lack of support for the hardware) is confirmed to be in the Linux kernel, it's being worked on upstream, and an experimental patch that enables the desired functionality is already available.

I've confirmed on my QX410 that a patched kernel works as desired, so it's not a problem in xserver-xorg-video-intel.

The bug remains as confirmed for Linux, as Natty's kernel doesn't include the (experimental) patch.

[EricDP (eric-arcticbears)]

The kernel patch is working quite well, so now back to Ubuntu: how do we get the patch integrated into the Ubuntu patched kernels for all supported versions so that the masses can benefit from it?

[Bryce Harrington (bryce)]

The process forward is to get the kernel team's attention on it. Jeremy Foshee (JFo) is the right contact point to work with to get priority attention placed on it. Ultimately the stable kernel maintenance team will need to review and/or backport the patch, so if things appear to stall on this bug report, try finding a kernel engineer to ask.

Sometimes attaching the patch(es) needing added, and/or pointing to a git branch with the fix staged can help accelerate the process of getting kernel team attention on it. Hope this helps, good luck.

[Arman Attarzadeh (arman-atz)]

Hey all,
Just wanted to say that this bug has affected me since Maverick. The upgrade to Natty and the new 2.6.38 kernel did not seem to fix it either...
However, I was reading that there is a patch released for it but I can't seem to access the Bugzilla page as it keeps giving me a 504 Gateway Error. Can someone attach the patch here for me and others who can't get to it?
Also, is it possible for me to recompile my Ubuntu kernel to include the patch?
Thanks!

[EricDP (eric-arcticbears)]

Patch for 2.6.38 attached. To build the module, here's what I did:

- ensure you have the kernel sources and kernel headers for 2.6.38
- cd into the directory with the source files elantech.c and elantech.h (I
believe it's ends with drivers/input/mouse in the source tree)
- to patch, do "patch < 01elantech_2.6.38.patch"
- to build, go back up to the root of your sources and do "make -C
/usr/src/linux-headers-`uname -r` SUBDIRS=`pwd`
drivers/input/mouse/psmouse.ko". You shouldn't get any errors. If you do,
ensure you are in the right directory.
- then cd back into the directory with the sources for elantech.(c|h) and you
should see a built psmouse.ko. Do "rmmod psmouse" to remove the current driver
from memory and "insmod ./psmouse.ko" to insert the new one. This will only
affect the running system--it will revert on reboot.
- if all works and you like it, you can install the new one by finding your
current psmouse.ko (probably somewhere like /lib/modules/(kernel
version)/kernel/drivers/input/mouse) and replacing it. Keep the original as
backup!

[EricDP (eric-arcticbears)]

And here is the patch for 2.6.35, compatible with maverick. I forgot to say above that the 2.6.38 works on natty. Both of these are the latest that are being testing upstream on bugzilla.kernel.org for anybody having trouble getting it from there.

These work quite well for me on my Samsung NF210. The pointer is a little jittery if I hold my finger still, but adjusting sensitivity makes it quite usable--quite a bit more usable than it was before with the tap-to-click always triggering.

You can disable tap-to-click and these also support two-finger scrolling.

[Andy Whitcroft (apw)]

These patches are vast, that makes them a trick proposition for us to take into the Ubuntu kernel without there being solid acceptance upstream. I do not yet see them in v2.6.39-rc's, does anyone know if they are being discussed for inclusion in mainline yet?

[Daniel Manrique (roadmr)]

Hi Andy,

The patch appears to still be quite experimental, that may be why it hasn't been proposed for integration upstream. Neither the bug discussion on kernel.org nor the mailing list for the involved kernel subsystem (see here: http://www.spinics.net/lists/linux-input/) seem to have anything definite about this, so there seems to be no public discussion to that effect.

Maybe some of the people involved (Tom Lin, for instance, the author of the original patch) could be discussing this privately, but if so, there's no indication to it.

This patch includes new Elantech models from previous patches and fixes excessive wobble on the ETF1059 (ETF5900) model used in the System76 Pangolin Performance model. We've created a DKMS module that we're distributing until the patch makes it upstream and into Ubuntu. You can use the module with the following commands:

sudo apt-get install dkms
cd /usr/src/
sudo wget http://planet76.com/drivers/elantech/psmouse-elantech-v6.tar.bz2

Just tested on sf510: edge-scrolling (new), 2-finer-scrolling (new), top-right-middle-click (new), tap (as before), tap-drag (as before) works.

It's great to have that touchpad working. Thank you all!

Ehr... as almost expected (but I didn't test that right away yesterday because I was at home and have been using a mouse):

Right click is not working yet.

I expected that because the Touchpad has a somehow really crooked design. There IS basically only one "button". And it's not a button. The design resembles that of the apple macbook touchpads, in that you can physically "click" it. But in contrast to the macbook's, the SF510's touchpad can only be clicked in a defined region at the bottom. In the top corners you CAN not click it by design, and the fact that you can click it right in the middle, I consider a manufacturing flaw. The clickable region is defined with a line that is imprinted on the touchpad surface and another line devides that region into a left and right part, which is, with the microsoft driver, used to distinguish between right and left click. It works, but it's crooked, because the driver software has to generate a left OR a right click event from ONE physical click signal, depending on where the finger is, during the click.

The lines on the touchpad and exact measurements of the touch sensitive area in mm look like this.

|47 mm |

(slowly getting used to 2-finger scrolling ... :-) great!)

[Patrick Pfeifer (patrick2000)]

I made this modifications to my psmouse dkms module and it works nicely for me. It gives me a right-click when i click on the lower right region of the "Elantech ETF1059 Click-Pad" as well as even a middle-click when i click exactly ON the vertical dividing mark in the middle of the lower region of the touchpad.

The top-right-middle-click-tapping-region is a bit too small and hard to hit, probably because the touchpad has rounded edges.)

my p.x values range from 0 (left) to 1467 (right) and the p.y values range from 0 (top) to 815 (bottom)

http://paste.ubuntu.com/627816/

It might be nice to have two-finger tap-drag mapped to middle-click-drag (for alt-middle-click-window-resizing or nautilus drag-n-ask-when-drop) ... has anybody got an idea how this could be achieved ?

[Patrick Pfeifer (patrick2000)]

I realize that there is quiet a difference between the p.y > 700 test i'm using and the calculated p.y == 628 position of the horizontal line of the touchpad. All I can say is that 700 works quiet well for me. (My index finger, in the middle of the "phalanx distalis" has a maximum width of around 18mm :)

[Benji (benjim)]

Same with a Samsung RC710. Work around from #59 works fine.

System: Xubuntu 11.04, XFCE4, Kernel 2.6.38(-8-generic)

[Piotr Sokół (psokol)]

Touchpad works great after doing Carl walk-through on RF510. Driver module should now compile and install when new kernel will be installed - am I right?
There is only one problem - after booting touchpad works fine on user selection screen, but when I log on, it's disabled. I can enable it only using /usr/bin/synclient TouchpadOff=0 command. Adding a proper option to Xorg.conf or adding this command to programs started automatically, didn't work. Anyone knows how to fix it?

[f_padia (f-padia)]

Cool. Using Carls patch in post #64 and Patricks update in post #94 my touchpad works well now on Samsung SF310. Thanks a lot guys!

[cuc (cuc+)]

thx carl (#64)

this patch fixed all my headaches with my new Asus A53SV/K53SV :) works perfectly now

[Oliver Joos (oliver-joos)]

I confirm that patch from comment 64 works on a Samsung SF510. But a right click is very hard to accomplish, also after applying the diff from comment 94. Tweaking its coordinates did not help either. But I found that right click gets easier if the pressed area is just big enough e.g. by holding the finger nearly parallel to the surface of the touchpad.

Thanks anyway! The patch finally allows that the touchpad is disabled while typing.

[malko (jgotti)]

Still don't work on rf710, the pad seems detected as an elantech, but it doesn't work at all .

[Rakitha S Beminiwattha (rakithab)]

My Asus U46E-BAL5 notebook had the same issue. It did not identify the ELAN touch pad when I installed Ubuntu 11.04, It was showing a Logitech PS/2 mouse. I followed the instructions given in Comment # 64 and now I have the touch pad correctly identified as,
ETPS/2 Elantech ETF1059 Click-pad.

This is really helpful and thank you so much!

    elantech.patch (50.8 KiB, text/plain)

This patch includes new Elantech models from previous patches and fixes excessive wobble on the ETF1059 (ETF5900) model used in the System76 Pangolin Performance model. We've created a DKMS module that we're distributing until the patch makes it upstream and into Ubuntu. You can use the module with the following commands:

sudo apt-get install dkms
cd /usr/src/
sudo wget http://planet76.com/drivers/elantech/psmouse-elantech-v6.tar.bz2
sudo tar jxvf psmouse-elantech-v6.tar.bz2
sudo dkms add -m psmouse -v elantech-v6
sudo dkms build -m psmouse -v elantech-v6
sudo dkms install -m psmouse -v elantech-v6

-- This has fixed my Asus k43e touchpad. It was recognized as logitec ps2 mouse before

[Seth Forshee (sforshee)]

The patch from comment #64 is unlikely to ever make it upstream or into Ubuntu. It changes too much in a single patch, it needs a lot of cleanup, and the upstream driver has moved on to the official multi-touch protocol.

I've used that patch as a reference for understanding the newer Elantech touchpad protocol and developed a patch that only adds support for this protocol. This is testing well for me on a Samsung NF310, but I'm not sure whether or not it will support the touchpads on all the models listed here. I've made builds for natty and oneiric in order to get testing on more hardware so we can find out.

Note that unless you are using oneiric you will still see the wobbly cursor issue. In oneiric this is fixed by filtering in xserver-xorg-input-synaptics. I have no plans to add any filtering to the driver.

The test builds are available at:

  http://people.canonical.com/~sforshee/lp681904/

After testing, please report back which hardware you tested on and whether or not it worked. If it doesn't work please attach the output of dmesg when running the test build. Thanks!

[Daniel Manrique (roadmr)]

Hi Seth,

I tested this kernel on a Samsung QX410 with Elantech touchpad, kernel version as follows:

Linux version 2.6.38-11-generic (root@tangerine) (gcc version 4.5.2 (Ubuntu/Linaro 4.5.2-8ubuntu4) ) #48~lp681904v201108052202 SMP Fri Aug 5 22:16:29 UTC

It works and feels very similar to the patch for #64 (which is what I use on my 2.6.38-10 current kernel), I tested tap-click and two-finger scrolling (vertical and horizontal) and they all work fine.

FWIW, on this particular laptop I don't get the wobbliness problem everyone talks about.

Relevant lines from dmesg:

[ 16.407116] elantech: assuming hardware version 3, firmware version 133.27.0
[ 16.443281] elantech: Synaptics capabilities query result 0x19, 0x14, 0x0c.

[ 16.621855] input: ETPS/2 Elantech Touchpad as /devices/platform/i8042/serio1/input/input8

Don't hesitate to let me know if you need more information about this system, or need me to perform more tests.

Thanks!

Hi Seth,

I confirm your patch works for me on an Asus X93S running Debian sid (Linux 3.0.0-1-amd64).

If this can help: I have created a DKMS source tree based on your patch for linux 3.0.

Installation instructions:
sudo apt-get install dkms

If you had install the module based on the patch of comment #64 of the original LP bug:
sudo dkms remove psmouse/elantech-v6 --all

cd /usr/src/
sudo wget http://people.debian.org/~julien/lp681904/psmouse-elantech-lp681904-1.tar.bz2
sudo tar jxvf psmouse-elantech-lp681904-1.tar.bz2
sudo dkms add -m psmouse -v elantech-lp681904-1
sudo dkms build -m psmouse -v elantech-lp681904-1
sudo dkms install -m psmouse -v elantech-lp681904-1

Please don't test the patch from comment #59. Either test the Ubuntu
builds from comment #111 or the dkms pakage from comment #113.

Yup, thanks Julien. I needed the dkms because I already have a "custom" kernel because of the "wavering vga problem" (lp:614238). Thanks Seth!

Yep, this is a side-effect of using the "real" multitouch protocol. This
is a class of device that is called semi-mt (semi-multitouch) in the
vernacular of the multitouch protocol, because it only provides limited,
somewhat unreliable information about multiple touches. For these
devices only basic, two-finger gestures are supported. We should be able
to special-case the xorg drivers to allow three-finger click and drag
for the elantech hardware because there's enough information to support
these, but that would be a follow-up to getting the new protocol support
into the driver.

Thanks for testing!

[Nick Leytem (nicholas-leytem)]

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.

[Seth Forshee (sforshee)]

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!

[Daniel Manrique (roadmr)]

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

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.

[Zaki Manian (zmanian)]

After install the .deb package from Seth,

sudo rmmod psmouse
sudo modprobe -a psmouse

you should get the following in dmesg

dmesg | grep elantech

[himegoto (larcsoul)]

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.

[EricDP (eric-arcticbears)]

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...

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

[himegoto (larcsoul)]

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.

[Seth Forshee (sforshee)]

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.

[f_padia (f-padia)]

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

[himegoto (larcsoul)]

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.

[EricDP (eric-arcticbears)]

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!

[himegoto (larcsoul)]

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.

[Nick Leytem (nicholas-leytem)]

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

[LD (ldwatson)]

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.

[Benji (benjim)]

@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.

[Nate Cox (akujin)]

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:

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

[Nick Campbell (nickcampbell18)]

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!

[nik.martin (nik-martin)]

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.

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.

synclient
Couldn't find synaptics properties. No synaptics driver loaded?

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
