Dell E7440 touchpad jumps position

This change was made by a bot.

Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem?

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.3 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'.

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

Thanks in advance.

My E7440 Laptop is 18 months old, I have seen the problem for about a year with 14.0.4, 15.04, and 15.10,
The problem was such a nuisance that I had abandoned both 14.0.4, and 15.04 after trying each version for about 1 week each.

Have tried downloading the mainline kernel according to the link, I think I have done it correctly, but info was not exactly as link.

I downloaded the 3 files and run the command line instruction.
This resulted in3 extra options appearing in the GRUB boot-loader under the Advanced options for Ubuntu tab;
Ubuntu with linux 4.3.0-040300-generic
Ubuntu with linux 4.3.0-040300-generic(upstart)
Ubuntu with linux 4.3.0-040300-generic(recovery mode)

I have used the "Ubuntu with linux 4.3.0-040300-generic" option to start Ubuntu,
The problem still happens the same as before, even when I start up wiith the new kernel,

>
Dell E7440 touchpad works correctly when freshly started each time; but after some time running the mouse pointer starts to randomly jumps position when I try to use the touchpad.
Once it occurs the problem is so bad that cannot use laptop with touchpad and need to shutdown.

If I shut down Ubuntu and re-start after about 10 seconds, the problem is temporarily resolved.
Both the USB Mouse and keyboard blue joy-button continue to work correctly while having "jumpy touchpad problem.
>

More details on problem,
It only seems to effect cursor vertical motion from touchpad control, and has the effect that when trying to place cursor on an object, the cursor initially moves well towards the object, but when I slow down movement to finely position on object, the cursor jumps away in a vertical direction (down if approach from below, upward if approached from above}

Having seen "penalvch" comment on the outdated bios on my laptop, I updated to the latest bios( a-16) three days ago.

The problem is still happening on A-16 bios and using kernel 4.3.0-040300

Hello,
Thanks for everyone's support; as a newbie to linux I do appreciate all the help.

Martyn, the issue you are reporting is an upstream one. Could you please report this problem following the instructions verbatim at https://wiki.ubuntu.com/Bugs/Upstream/kernel to the appropriate venue (Dmitry Torokhov CC linux-input)?

Please provide a direct URL to your newly made report when it becomes available so that it may be tracked.

Thank you for your understanding.

Using the instructions in the link above, with Linux kernel 4.3.0-040300-generic, I created the report which I emailed in text only format on 20th November to <email address hidden>, cc <email address hidden>
I have not had any response to this submission.

I have recently checked and the problem still exists on later kernel Linux version 4.4.0-040400rc3-generic
I created a new report as before, which I emailed in text only format on 7th December to <email address hidden>, cc <email address hidden>

Martyn, could you please provide a URL of your posts from the mailing list as previously requested?

Christopher,
How do I find the URL to the posts from the mailing list, (as previously requested)?
I was expecting to see a new item in the bugzilla.kernel.org/buglist, and thought that you wanted me to provide a URL to it; but can't see any new entry regarding my report.
Or am I looking in the wrong place for the URL?
Martyn

Martyn, consulting https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1513914/comments/9 :
"Please ensure you post in your Launchpad report a URL of your e-mail from the mailing list found from the mailing list archives[URL]. It can take a day or two for the e-mail to show up to the respective archive. "

[URL] http://vger.kernel.org/vger-lists.html

I would like to be able to post the URL, but how do I find it?

I have not had any replies to the two reports which I emailed to <email address hidden> with cc to <email address hidden> (on 20th November for results with kernel 4.3.0-040300-generic) and on 7th December for results with kernel 4.4.0-040400rc3-generic)
Also, I have searched the forum for any posting relating to my problem and not found any.

Which archive at VGER.KERNEL.ORG should I be looking at to find the URL to post?

I have also checked with kernel's 4.4.0-040400rc5-generic and 4.4.0-040400rc7-generic, and the problem does still exist.

Since 6th January, have been checked with latest upstream kernel 4.4.0-040400rc8-generic and the bug still exists.

I have submitted a new report for latest upstream kernel 4.4.0-040400rc8-generic to <email address hidden>, cc <email address hidden>.

I will post URL when I get one.

Still happening with the new upstream kernel 4.4.0-040400-generic_4.4.0-040400.201601101930_amd64.deb

Also recently reported by other user on https://bugs.launchpad.net/bugs/1272624.

Still happening with 4.5.0rc5;
Will check with 4.5.0 wily release 14/03/2016

The problem still exists after the following updates /upgrades:
bios updated to version a17, Ubuntu upgraded to 16.04 LTS, and using upstream kernel V4.6-rc5-wily

The response to the above terminal command is:

A17

Update, a new version of Dell Latitude E7440 bios(version A18) was released 4th May 2016

Now checking with A18 bios (dated 04/28/2016), Ubuntu 16.04 LTS, and Kernel 4.6 rc7;
Will update results

The problem still exists when running E7440, A18 bios, Ubuntu 16.04 LTS and Kernel 4.6rc7
Martyn

I am using the A18 bios, and the release date according to Dell US website was 04 May 2016, so I think it is the latest bios.

The output of the "sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date" is:

By the way, the A18 bios seems to have fixed the problem of not reading SD cards, which was introduced with bios A16 & A17

The problem still exists when running E7440, A18 bios, Ubuntu 16.04 LTS and Kernel v4.6-yakkety (2016-06-03 14:14)

I am unable to try with Kernel v4.7rc1-yakkety (2016-05-29 18:30) as this Kernel version fails to complete the boot process (reports UUID xxxx does not exist error)

2. xubuntu 19.04, linux 5.0.0-37-generic

Dell BIOS A27 (date: 31.10.2018)

Pawel Por (porparek), it is most helpful to provide necessary debugging information via a terminal:
