Touchpad not recognised on Dell Latitude E6230, 6330, 6430, 6530, 5430, 5530

[Erno Kuusela]

lsinput just shows a PS/2 mouse.

This would be important to fix because the touchpad isn't configurable and is hard to use because it's
so close to kb & can't configure to ignore touches coinciding with keypresses.

It looks like similar bugs were recently fixed in Precise for some other Dell models: #606238 and #978807

[Emmanuel Thomé (emmanuel-thome)]

You are well right posting a new bug. Bug 606238 was really too crowded.

As far as I am aware, no, there is nothing in the current ubuntu kernel for having this issue fixed.

I hacked a dklm replacement, building on top of Dave Turvene's and Ben Gamari's work. Code is here.

git://github.com/emmanuelthome/psmouse-alps.git

Real place for this fix is upstream, though. I haven't contacted upstream yet, being busy at other things.

[Joseph Salisbury (jsalisbury)]

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.7 kernel[0] (Not a kernel in the daily directory) and install both the linux-image and linux-image-extra .deb packages.

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.

No change with kernel from http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.7-raring/linux-image-3.7.0-030700-generic_3.7.0-030700.201212102335_amd64.deb

[Erno Kuusela (erno-iki)]

@emmanuel-thome: that seems to work, nice job! But too hard for average user, this needs to be fixed in Ubuntu too.

[Joseph Salisbury (jsalisbury)]

@emmanuel-thome,

Do you plan on sending your fixes upstream?

[Kent Baxley (kentb)]

These are the patches that I think have gone upstream and look to be in 3.9rc1

http://thread.gmane.org/gmane.linux.kernel.input/29102
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/log/drivers/input/mouse/alps.c?id=refs/tags/v3.9-rc1

The patches have been confirmed to work on Latitude 6230, 6530, and 6430 hardware.

[Joseph Salisbury (jsalisbury)]

Do you know if these patches were also requested for inclusion in the upsteam linux-stable trees?

[Kent Baxley (kentb)]

@ Joseph, I'm not sure what the status is with regard to linux-stable. I know that Fedora is carrying the support as patches in their F17 / F18 kernels for the time being: https://bugzilla.redhat.com/show_bug.cgi?id=812111#c88

[James M. Leddy (jm-leddy)]

In addition, we need commit 3b112923, and "[PATCH V2 06/14] Input: ALPS - Use function pointers for different protocol handlers" from the list needs to be reworked since we never backported b4adbbef to the ubuntu kernel.

I don't think -stable accepts patchsets like this, but I'd be willing to post there if we can find evidence otherwise.

[James M. Leddy (jm-leddy)]

I've built a test kernel with an updated v3.9-rc1 driver that can be found at:

http://people.canonical.com/~jmleddy/.private/updatealps/

Also kentb has done some testing on at least 3 Dell skus and has found that kernel to fix the existing problems.

[Tim Gardner (timg-tpi)]

I applied all ALPS patches since v3.8:

git log --pretty=oneline v3.8..v3.9-rc3 -- drivers/input/mouse/alps.*

[James M. Leddy (jm-leddy)]

Adding linux-lts-quantal for clarity, since obviously this will come to precise through the backports kernel.

[Brad Figg (brad-figg)]

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed' to 'verification-done'.

If verification is not done by one week from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!

[Kent Baxley (kentb)]

Tested -proposed kernel on a Latitude E5430.

xinput now sees the touchpad as "AlpsPS/2 ALPS DualPoint Touchpad".

There are options now in mouse and touchpad preferences to configure edge and horizontal scrolling (There is also an option to do two-finger scrolling but it currently doesn't work, and I don't think that's actually been fixed anywhere, yet, so that's ok for now...single-finger scrolling is welcome enough at this point).

I can also enable and disable the touchpad via the fn+F5 hotkeys on this laptop.

Nice work, and thanks for pulling in the patches.

[Erno Kuusela (erno-iki)]

 Fix works on E6230 on precise, after enabling proposed & getting linux-image-generic-lts-quantal

[Adam Conrad (adconrad)]

The verification of this Stable Release Update has completed successfully and the package has now been released to -updates. Subsequently, the Ubuntu Stable Release Updates Team is being unsubscribed and will not receive messages about this bug report. In the event that you encounter a regression using the package from -updates please report a new bug using ubuntu-bug and tag the bug report regression-update so we can easily find any regresssions.
