[Clausoft Meenee MNW737 PX1] Synaptics Touchpad incorrectly detected as PS/2 mouse

[Ed S]

There's no touchpad tab in the system/prefs/mouse control panel. gconf-editor has a button to disable tap-to-click but it has no effect. Xorg log does not mention synaptics. /proc/bus/input/devices does not mention synaptics. The tpconfig tool is unable to adjust zthreshold or disable tap to click. tpconfig reports this:

# tpconfig -D1 -z0
Probing mouse port [/dev/psaux].
Grabbing mouse port [/dev/psaux].
Trying Synaptics detection.
[query 00 => 0x60 0x3 0xc8]
Found Synaptics Touchpad.
[query 0x3 => 0x60 0x3 0xc8]
Firmware: 8.96 (multiple-byte mode).
Z threshold set as "0".
[query 0x1 => 0x60 0x3 0xc8]
[query 0x1 => 0x60 0x3 0xc8]
Z threshold: 6 of 7.

Strictly, the touchpad is detected as "ImPS/2 Generic Wheel Mouse" according to /proc/bus/input/devices

I've reported this as linux (kernel) problem according to advice on https://wiki.ubuntu.com/DebuggingTouchpadDetection

From that page there's just one similar open known bug, which relates to ALPS hardware (so is different)

As evidence that this is synaptics hardware the vendor provides a windows driver with this identifying info
DriverVer=08/27/2009, 14.0.3.0

booted from Natty 11.04 liveusb and reproduced the problem, ran apport-collect as advised.

[Ed S (ed-spittles)]

tested in 10.10 maverick with upstream kernel
2.6.39-999-generic #201105130905
with same results.

Cannot presently test 11.04 natty with upstream kernel because it fails to recognise any input devices.

[Ed S (ed-spittles)]

collected some lowlevel debug i/o from the touchpad device by following this procedure:

  826 sudo rmmod psmouse
  827 dmesg>dmesg.log.0
  828 echo 1 |sudo tee -a /sys/module/i8042/parameters/debug

see also bug 550625 where, in comments #182 and #341 users jzachariou and adrian-wechner report the same E6 and E7 ID that I do:

and see also http://ubuntuforums.org/showthread.php?t=1835556
user "Darngood" aka Dan reports similar trouble with his Dell Inspirion N5110

So this touchpad hardware is found in
clausoft MNW737 (meenee)
ASUS Eee 1015PED
Dell Inspirion N5110 ... aka Dell 15R
(and is not fixed by the fix to the ALPS driver change pertaining to bug 550625)

[Ed S (ed-spittles)]

sorry, typo, that's Dell Inspiron N5110

[Ed S (ed-spittles)]

On further info from Seth Forshee, it seems that Dell N5110 probably has ALPS hardware. The E6/E7/psmouse reports I gave perhaps only mean that the specific device was not detected.

It also seems that the ASUS Eee 1015PED probably has ElanTech hardware.

[Ed S (ed-spittles)]

I've reconfirmed this problem with the Beta 2 of ubuntu 11.10 (oneiric) - touchpad is detected as a mouse, so I have no touchpad controls, so cannot disable tap to click.

⎜ ↳ ImPS/2 Generic Wheel Mouse id=12 [slave pointer (2)]

[Leo Iannacone (l3on)]

Problem is still present in Ubuntu 11.10.

[Leo Iannacone (l3on)]

Problem also confirmed on:

 Linux meenee 3.2.0-1-generic #3-Ubuntu SMP Tue Nov 22 11:17:48 UTC
2011 i686 i686 i386 GNU/Linux

[Ed S (ed-spittles)]

Thanks for confirming it's still a problem in new linux kernel. And very good to see someone else with the same hardware and an interest in finding a fix.

Why did you change "affects"? I'm pretty sure this is a linux kernel problem, specifically a driver problem.

See similar bug 606238 and particularly comment 77 where Seth Forshee points to his blog entry, where he describes how to get started reverse-engineering touchpad protocols. He did this successfully for the ALPS driver and his fixes have been submitted upstream. See his comment 492 on Bug 550625 for his DKMS package.

I think I've established that the hardware on this meenee is not ALPS and is not helped by Seth's specific fix to drivers/input/mouse/alps.c

I can't apply his tactics to snoop on the touchpad protocol until I can get hold of a USB CD drive.

[Leo Iannacone (l3on)]

About bug report: Yes, You're right... sorry.

Changed to Ubuntu (linux).

[Joseph Salisbury (jsalisbury)]

Would it be possible for you to test the latest upstream kernel? It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . If possible, please test the latest v3.2-rcN kernel (Not a kernel in the daily directory). Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag(Only that one tag, please leave the others). This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text.

If this bug is fixed by the mainline kernel, please add the following tag 'kernel-fixed-upstream-KERNEL-VERSION'. For example, if kernel version 3.2-rc1 fixed and issue, the tag would be: 'kernel-fixed-upstream-v3.2-rc1'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'. If you believe this bug does not require upstream testing, please add the tag: 'kernel-upstream-testing-not-needed'.

Thanks in advance.

[Leo Iannacone (l3on)]

With v3.2-rc2 nothing changes.

There is no Kernel v3.2-rc3 deb in:
http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.2-rc3-oneiric/

So I can test it with latest version...

Therefore, I'm waiting for it before update tags.

(With this kernel I have no networking, so not so easy to work with. In
particular, not so easy to get necessary packages to rebuild modules.)

[penalvch (penalvch)]

Ed S, thank you for testing Quantal and the mainline kernel.

Could you please execute the following in a terminal, and post the results to this report as an attachment:
cat /var/log/Xorg.0.log > Xorg.0.log

[Ed S (ed-spittles)]

Here's the Xorg.log
(The problem has been established as being a failure of psmouse.ko to
detect the protocol of this model of touchpad as synaptics. Once the kernel
has failed in that way, X doesn't have a chance. The fix is going to be a
change to that kernel module. I've previously provided serio debug output
which should enable someone to see where the code is going astray, although
it won't tell us how this protocol works. In the case of a similar problem
with ALPS, I think it turned out to use an existing protocol variant but
with a novel identification sequence.)
I'd be happy to load a psmouse.ko with extra instrumentation or a fix, but
I'm not likely to dive into building a module myself.
Cheers
Ed

Same breakage exists with rc5 (#201209082035 version): /sys/class/input/mouse0/device/name reads "ImPS/2 Generic Wheel Mouse"
I've reverted to "confirmed"
Please don't ask for pointless testing - if there's no proposed fix in the kernel it's a waste of my time and remaining goodwill.
Thanks.

Ed S, thank you for testing the newest mainline kernel.

Regarding your comments https://bugs.launchpad.net/ubuntu/+source/linux/+bug/755518/comments/87 :
"Please don't ask for pointless testing..."

Please do not presume the required testing was pointless. As per Ubuntu Kernel Team and Ubuntu Bug Control policy, one must test the newest mainline kernel available, and provide the necessary debugging information, to have this marked Triaged, or a state where a developer could begin working on this. For more on this please see https://wiki.ubuntu.com/KernelTeam/KernelTeamBugPolicies#Bug_Triage .

Regarding your comments https://bugs.launchpad.net/ubuntu/+source/linux/+bug/755518/comments/88 , no need exists at this time to provide debugging information not requested of you from the debugging articles previously mentioned, triager, or developer.

Despite this, the issue you are reporting is an upstream one. Could you please report this problem through the appropriate channel by following the instructions _verbatim_ at https://wiki.ubuntu.com/Bugs/Upstream/kernel#KernelTeam.2BAC8-KernelTeamBugPolicies.Overview_on_Reporting_Bugs_Upstream ?

Thank you for your understanding.

Marking Triaged as mainline tested and all required debugging information provided.

     (This is a move upstream for a bug reported on Ubuntu's Launchpad
tracker (https://bugs.launchpad.net/ubuntu/+source/linux/+bug/755518),
please bear with me.)

    A laptop sold with Ubuntu linux in 2010 has an misdetected touchpad.

    We're told by the manufacturer that it's a Synaptics controller, and
the Synaptics driver supplied by them for Windows is dated 08/27/2009. The
problem persists with a range of kernel versions, up to and including a
recent 'rc5' 'mainline' kernel built by ubuntu.

    I tried to install Windows to a virtual machine with the aim of
investigating with the Synaptics driver, but failed to complete the
installation. I'm willing to try modules or patches. There are 6 other
Launchpad users with the same problem, hopefully we can help you to help us.

    Thanks
Ed

    Here's the problem info in the format advised by Ubuntu (which makes
this a long email, but hopefully useful):

[1.] One line summary of the problem:

Synaptics Touchpad incorrectly detected as PS/2 mouse on clausoft MNW737
(aka meenee, aka PX1)

[2.] Full description of the problem/report:

There's no touchpad tab in the system/prefs/mouse control panel.
gconf-editor has a button to disable tap-to-click but it has no effect.
Xorg log does not mention synaptics. /proc/bus/input/devices does not
mention synaptics. The tpconfig tool is unable to adjust zthreshold or
disable tap to click. tpconfig reports this:

# tpconfig -D1 -z0
Probing mouse port [/dev/psaux].
Grabbing mouse port [/dev/psaux].
Trying Synaptics detection.
[query 00 => 0x60 0x3 0xc8]
Found Synaptics Touchpad.
[query 0x3 => 0x60 0x3 0xc8]
Firmware: 8.96 (multiple-byte mode).
Z threshold set as "0".
[query 0x1 => 0x60 0x3 0xc8]
[query 0x1 => 0x60 0x3 0xc8]
Z threshold: 6 of 7.

Strictly, the touchpad is detected as "ImPS/2 Generic Wheel Mouse"
according to /proc/bus/input/devices

I've reported this as linux (kernel) problem according to advice on
https://wiki.ubuntu.com/DebuggingTouchpadDetection

From that page there's just one similar open known bug, which relates to
ALPS hardware (so is different)

As evidence that this is synaptics hardware the vendor provides a windows
driver with this identifying info
DriverVer=08/27/2009, 14.0.3.0

Please do not use tpconfig utility, it hasn't worked since 2.5 kernels.

Can you please simply boot with i8042.debug kernel option and post your
entire dmesg instead?

Thanks.

This bug was filed against a series that is no longer supported and so is being marked as Won't Fix. If this issue still exists in a supported series, please file a new bug.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.

[penalvch (penalvch)]

Marking Triaged as the bot marked this report Won't Fix in error, as this has been reproduced in Quantal and mainline kernel, and reported upstream.

[penalvch (penalvch)]

Ed S, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ .

If it remains an issue, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report:

apport-collect -p linux <replace-with-bug-number>

Also, could you please test the latest upstream kernel available (not the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested. For example:
kernel-fixed-upstream-v3.13-rc1

This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag:
needs-upstream-testing

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

As well, please remove the tag:
needs-upstream-testing

Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results. Thank you for your understanding.
