[Dell Latitude XT2] Touchpad detected as ps/2 mouse in Ubuntu 13.04

[Marty Plummer]

The included touchpad is detected as a ps/2 mouse, and it is impossible to set most standard touchpad options (edge/2 finger scrolling, etc)

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.11 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

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'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

[Marty Plummer (ntzrmtthihu777)]

Tested kernel 3.11 rc6, same results, getting two-finger/edge scrolling is impossible and device is still reported as ps/2 mouse.

[penalvch (penalvch)]

Marty Plummer, could you please execute the following at a terminal and post the results to this report:
cat /proc/bus/input/devices

[Marty Plummer (ntzrmtthihu777)]

results of said command.

[penalvch (penalvch)]

Marty Plummer, could you please confirm this issue exists with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ . If the issue remains, 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:

The issue remains; it also exists within my arch linux install using kernel 3.11-1

[penalvch (penalvch)]

Marty Plummer, did this problem not occur in a release prior to Raring?

[Marty Plummer (ntzrmtthihu777)]

Not personally; I installed raring immediately after getting this laptop. However, this bug has been reported for previous versions here; in fact I started this bug report because I posted that this bug affects me on an older versions's bug report; I can't seem to find it now, though.

[penalvch (penalvch)]

Marty Plummer, for regression testing purposes, could you please Lucid via http://old-releases.ubuntu.com/releases/lucid/ ?

Marty Plummer, so in Lucid, are you able to set any desired option (ex. edge/2 finger scrolling, etc.)?

[Marty Plummer (ntzrmtthihu777)]

Sorry about that, I lost connection shortly after running apport against this bug. No, it still functions only as a simple ps/2 mouse, and I cannot set any standard touchpad options.

[Marty Plummer (ntzrmtthihu777)]

Crap, I don't have (nor do I intend to) saucy installed; I've tested against saucy for you by booting the iso from hdd using grub2, but I can't do that with the 3.12 kernel because I'd need to reboot, and since that's a live environment it won't keep the changes.

Could an iso with 3.12 be built? And if so, could you get me some instructions, mayhaps?

[penalvch (penalvch)]

Marty Plummer, you may test the latest mainline kernel, which is now http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.12-rc4-saucy/ , in your current install. You would not need to test the latest mainline kernel in Saucy at this time.

[Marty Plummer (ntzrmtthihu777)]

Still an issue. I've switched to arch linux and was testing via live iso, so I can't do that in my current install. Would a vm work the same, or not? I *could* install ubuntu on a partition temporarily but I'd like to avoid that if possible, as I no longer use ubuntu. I just want to follow through with this bug report to the end for the sake of all linux users, regardless of distro. I can install 3.12 kernel on arch via the aur, would that be valid?

[Marty Plummer (ntzrmtthihu777)]

Nevermind, just realized I'm an idiot. I have two perfectly good usb sticks I can install ubuntu to and the mainline kernel debs, so I can still test this properly. Having some domestic issues, but I will get it tested within a day or two.

[Marty Plummer (ntzrmtthihu777)]

Just tested against the latest mainline kernel on Ubuntu Raring, same issue. Apport information to follow.

[Marty Plummer (ntzrmtthihu777)]

apport information

[Marty Plummer (ntzrmtthihu777)]

Dangit, its not reporting properly. "No package named linux"

[Marty Plummer (ntzrmtthihu777)]

apport information

[Marty Plummer (ntzrmtthihu777)]

Ok, this is not working. I await further instruction, as apport-collect -p linux 1215589 does not work and returns the contents of HookError_cloud_archive.txt in terminal.

[penalvch (penalvch)]

Marty Plummer, don't worry about submitting apport-collect on mainline kernels, as apport is not designed to this. One may just make a comment to the test results.

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.

Description of problem:

  At present, the ALPS DualPoint TouchPad is not supported under Linux, being
  recognised as a PS/2 mouse only.

  Tommy Will / Yunkang Tang from ALPS has written a kernel patch adding support
  for it (attached), which he'll submit to the upstream linux-input mailing
  list soon.

  The patch has been tested successfully by Gaspard Jankowiak, a Fedora
  Community member with this hardware. He used a Fedora 19 kernel built by
  Niels de Vos, with the patch added for this purpose.

  This BZ is mostly for tracking, so that if/when the patch is accepted
  upstream, it can be pulled into the relevant Fedora 19 kernel.

Version-Release number of selected component (if applicable):

  Linux kernel 3.11.x

[Justin (justin-redhat-bugs)]

The feedback from Gaspard (copied from email):

  The touchpad is now recognized, edge scrolling is working, and
  two-finger scrolling is not.

  dmesg snip:
  [ 2.786816] input: AlpsPS/2 ALPS DualPoint TouchPad as
  /devices/platform/i8042/serio1/input/input5

  Tested with
  Name : kernel
  Version : 3.11.6
  Release : 200.0.bz953211.2.fc19
  Architecture: x86_64

Note - 2 finger scrolling is not supported by the hardware, so this is
as expected. :)

Linux kernel patch adding support for Dell XT2 touchpad

[gj (g-j)]

A patch has been baked by Redhat and is being submitted upstream:
https://bugzilla.redhat.com/show_bug.cgi?id=1023413

[Josh (josh-redhat-bugs)]

Justin, I'm confused. How is this bug any different from the tracking bug we have for this already, which is bug 953211 ?

Did I miss some subtlety here?

[Justin (justin-redhat-bugs)]

Yeah, they're for different hardware (although still from ALPS).

The patch for BZ 953211 doesn't help with the touchpad on the Dell XT2, thus the patch in this BZ (and it's just a 1-liner).

Is that clearer now? :)

[Josh (josh-redhat-bugs)]

Ah, I see. I should have just read the patch. We're just adding a device ID to the existing support here, right?

> Is that clearer now? :)

Yes, thank you.

[Justin (justin-redhat-bugs)]

(In reply to Josh Boyer from comment #5)
> We're just adding a device ID to the existing support here, right?

Yep. :)

[Josh (josh-redhat-bugs)]

OK. I'll try and get this added today. I believe this is queued in the input tree upstream?

[Justin (justin-redhat-bugs)]

Thanks Josh:

The patch was submitted to the linux-input mailing list today:

Marty Plummer, could you please test the development release via http://cdimage.ubuntu.com/daily-live/current/ and advise if this is reproducible? It contains the upstream fix previously discussed:
http://kernel.ubuntu.com/git?p=ubuntu%2Fubuntu-trusty.git&a=search&h=HEAD&st=author&s=Yunkang+Tang

[Marty Plummer (ntzrmtthihu777)]

Will do asap, but I will say that my current kernel on archlinux contains the patch, so I assume upstream has it in the mainline kernel. As my internet connection is less than adequate as of now I'll have to wait to be able to download the latest iso, but I will test as soon as I can.

[penalvch (penalvch)]

EOL release, and patch to address submitted upstream.
