Synaptics s3203 touchpad not working after update to kernel 4.15.0-72-generic

[Lewi S. Kristianto]

SRU justification
=============
[Impact]
Synaptics s3203 touchpad not working after update to kernel
4.15.0-72-generic

[Fix]
After applied commit "Input: synaptics-rmi4 - avoid processing unknown
IRQs",
no irq response from touchpad.
This commit is depended on commit:
"Input: synaptics-rmi4 - convert irq distribution to irq_domain"

[Test]
Verified on hardware, tests results are good.

[Regression Potential]
Low.
Fix bug that introduced by stable release update.

2nd and 3rd patches are fixes for the 1st patch.
These commits are already included by eoan kernel, so bionic 4.15 only.

[Ubuntu Kernel Bot (ubuntu-kernel-bot)]

This change was made by a bot.

[Kai-Heng Feng (kaihengfeng)]

Can you please find the last working kernel?

[Lewi S. Kristianto (lewi)]

Hi Kai Heng,

using grub-customizer, changing default boot to vmlinuz-4.15.0-72-generic, touchpad is working

[Lewi S. Kristianto (lewi)]

*sorry mistyped, previous using working kernel vmlinuz-4.15.0-70-generic.

[Kai-Heng Feng (kaihengfeng)]

Somehow the device is (incorrectly) bound to hid-rmi instead of hid-multitouch.

I don't find any outstanding commits from HID subsystems between the two kernel versions though.
Since hardwares at my hand don't have this issue, the quickest way is to perform a kernel bisection by you.

$ sudo apt build-dep linux
$ git clone git://git.launchpad.net/~ubuntu-kernel/ubuntu/+source/linux/+git/bionic linux
$ cd linux
$ git bisect start
$ git bisect good Ubuntu-4.15.0-70.79
$ git bisect bad Ubuntu-4.15.0-72.81
$ make localmodconfig
$ make -j`nproc` deb-pkg
Install the newly built kernel, then reboot with it.

If it still have the same issue,
$ git bisect bad
Otherwise,
$ git bisect good
Repeat to "make -j`nproc` deb-pkg" until you find the offending commit.

[AaronMa (mapengyu)]

https://lists.ubuntu.com/archives/kernel-team/2019-December/106108.html

Please stay at 4.15.0-70 kernel or apply the patches above in maillist.
The fix should be in next release.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Alberto Pianon (alberto-o)]

It affects also my Lenovo Yoga 3 11 with touchpad Synaptics TM2714-002

[Philip Parry (philip.parry)]

I have the same problem; Lenovo Yoga 3 11, Synaptics TM2714-002, touchpad not working after update to kernel 4.15.0-72-generic, reboot with 4.15.0-70 and it works fine.

[AaronMa (mapengyu)]

Could you test the following kernel ppa please:

sudo add-apt-repository ppa:mapengyu/bionic-oem
sudo apt-get update

sudo apt install linux-image-unsigned-4.15.0-73-generic linux-modules-4.15.0-73-generic linux-modules-extra-4.15.0-73-generic

[Jorgehn (jlainezbonilla)]

I have tried what described by AaronMa (apengyu) and now the touchpad of my Dell Inspiron works perfectly. Thank you so much.

[AaronMa (mapengyu)]

Could you try the bionic kernel 4.15.0-73 from the proposed channel?

If you already installed the kernel from my ppa, please remove the debs first.

Thanks.

[Lewi S. Kristianto (lewi)]

after disable secure boot in the bios,
confirmed that 4.15.0-73 unsigned is working on dell xps-9333

Great (y)

[Khaled El Mously (kmously)]

The following link contains a test kernel that can be used to confirm the fix for this issue:

https://kernel.ubuntu.com/~kmously/kernel-kmously-2019795-5QnR/

This kernel is the 4.15.0-72-generic kernel plus one change: Revert 'Input: synaptics-rmi4 - avoid processing unknown IRQs'

For anyone testing this kernel, a minimum of 2 files need to be installed:

linux-image-unsigned-4.15.0-72-generic_4.15.0-72.81~k1_amd64.deb
linux-modules-4.15.0-72-generic_4.15.0-72.81~k1_amd64.deb

[Jorgehn (jlainezbonilla)]

I did it from the proposed channel and the touchpad works perfectly, but
when will the kernel be available from the official channels?. Again thanks
you so much.

[GShyam (ghanshyam99)]

I tried the commands written by AaronMa, but it did not work. So, I just boot with 4.15.0-70-generic.

[Jorgehn (jlainezbonilla)]

I did it from the proposed channel and the touchpad works perfectly, but when will the kernel be available from the official channels?

[Andreas Kaspar (kandy100)]

Hi all
got the issue on Thinkpad X1 Carbon 6th.
dmesg:
input: Synaptics TM3288-011 as /devices/rmi4-00/input/input20
cheers
Andy

[Albert Pool (albertpool)]

Just got the -73 kernel running properly on Xenial (it refused to load modules at first)

The Synaptics TM3289-002 touchpad in my Lenovo ThinkPad X1 Carbon 5th generation works again.

[KS (softwareguy101)]

Hi all,

Getting this issue as well I think on my Lenovo Ideapad 320. My touchpad is Synaptics TM3336-001.
Should I try booting with a different kernel, or is there a temporary fix for this available yet?

[Fabrício Pereira (fabriciorsf)]

Is the same problem reported by me?
https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-input-synaptics/+bug/1855172

[KS (softwareguy101)]

Yes. I too tried to running sudo apt install xserver-xorg-input-synaptics among other potential options. Nothing has worked so far.

[KS (softwareguy101)]

Update: I managed to revert my kernel to 4.15.0-70-generic through the bootloader menu that appears at the start of my laptop, and my touchpad has started working again. I'll keep using this version until a stable fix is pushed

[Richard Brooksby (rptb1)]

I can report that the test kernel in #11 fixes this issue for my HP Stream 11 laptop, confirming that https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1856042 is a duplicate of this.

[viv (vivkar)]

I have a dell machine, Synaptics TM3108-002 touchpad, ubuntu 18.04.3 LTS.
I faced the same problem after update to kernel 4.15.0-72-generic, touchpad stopped working. I was directed to this link and it kind of solved my problem. I initially wanted to reboot it with kernel 4.15.70-generic but did not know how to do it and the easier option I found was @AaronMa solution.

sudo add-apt-repository ppa:mapengyu/bionic-oem
sudo apt-get update

sudo apt install linux-image-unsigned-4.15.0-73-generic linux-modules-4.15.0-73-generic linux-modules-extra-4.15.0-73-generic

After I followed his solution, touchpad started working again

Question: Since I get it from ppa associated with mapengyu, is it a legit ubuntu kernel. I mean it works fine for now but in future will it get normal ubuntu updates as generally my machine gets? So, suppose the ubuntu software updater wants to update it from 4.15.0-73-generic to 4.15.0-75-generic in future, will it accept the updates and in tun apply the update?

Question: why does this ppa come from a private user mapengyu and not from ubuntu folks itself?

Question: For how long do I need to keep the ppa mapengyu added to my machine. In future can I remove it?

Question : How do I reboot my machine with kernel 4.15.0-70-generic? (this is just from my curiosity and not need because @AaronMa suggestion, made my tochpad responsive again)

[cbologa (cbologa)]

Same problem here. Trackpad Synaptics TM3066-002 stopped working in Lenovo Yoga 900-13ISK after upgrade to kernel 4.15.0-72. When restarting with kernel 4.15.0-70 it works. I am eagerly waiting for the kernel update that is going to solve this problem!

[Iyed (iyed-bennour1)]

Configured grub to show the grub menu and selection kernel 4.15.0-70-generic I got the touchpad to work again. The problem appeared with 4.15.0-72.

I you can do that instead of installing a kernel from a non official source.

[KS (softwareguy101)]

@vivkar, in response to your last question, you should have kernel 4.15.0-70-generic already available to boot from, since an update wouldn't have replaced the old kernel version. Make sure it's not available by going to /boot/ folder on your machine and looking for any files named 4.15.0-70-generic.

If it is not available, perhaps you can try manually downloading the kernel version and then following the instructions in https://superuser.com/questions/208502/how-to-add-a-new-kernel-to-grub2. I'm a complete linux newbie, so take my advice with a grain of salt. If the the 73 version of the kernel is working for you right now, I think you should stay on it until an update becomes available.

I'm not sure about the answer to your other questions

[Nath Stone (nathstone87)]

Hi - message for AaronMa (mapengyu)

I can confirm your steps work in the post above.

I upgraded my kernel to '4.15.0-72-generic' and my touchpad stopped working

Touchpad Hardware is: Synaptics TM2976-002

My touchpad now works again after the following steps:

Could you test the following kernel ppa please:

sudo add-apt-repository ppa:mapengyu/bionic-oem
sudo apt-get update

sudo apt install linux-image-unsigned-4.15.0-73-generic linux-modules-4.15.0-73-generic linux-modules-extra-4.15.0-73-generic

Note: For anyone else out there that needs this fix, if you are using the broadcom-sta ko for your wireless and it is loaded via dkms, you will also need to install the kernel headers in order for dkms to do its thing

sudo apt-get install linux-headers-4.15.0-73-generic

Thanks to AaronMa/whomever fixed the bug

[Ankush singh (ankush947)]

Can someone with the right permissions mark at the top that the bug equally affects Xenial?

@albertpool - it only impacts (as reported) 16.04 LTS WHEN using the 18.04/HWE kernel. To my knowledge there are no reports of it impacting xenial users using 16.04's 4.4 kernel.

4.15.0-70-generic runs fine with touchpad

Sorry, not a programmer. Received E-Mail back with below fix but too
inexperienced to figure out how to use it:

SRU justification
=============
[Impact]
Synaptics s3203 touchpad not working after update to kernel
4.15.0-72-generic

[Fix]
After applied commit "Input: synaptics-rmi4 - avoid processing unknown
IRQs",
no irq response from touchpad.
This commit is depended on commit:
"Input: synaptics-rmi4 - convert irq distribution to irq_domain"

[Test]
Verified on hardware, tests results are good.

[Regression Potential]
Low.
Fix bug that introduced by stable release update.

2nd and 3rd patches are fixes for the 1st patch.
These commits are already included by eoan kernel, so bionic 4.15 only.

Original reports
===========================================================

Any help greatly appreciated. Thanks

Follow this steps, it works for me:

1. Run
    $ sudo -H gedit /etc/default/grub

In the open window edit line

    GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

it should look this way

    GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i8042.nopnp"

Save file and run

    $ sudo update-grub

2. Run
    $ echo "blacklist i2c_hid" | sudo tee /etc/modprobe.d/i2c-hid.conf
    $ sudo depmod -a
    $ sudo update-initramfs -u
    $ echo "synaptics_i2c" | sudo tee -a /etc/modules

3. Reboot.

Hello Nilesh,

Amazing bro. It worked flawlessly . I was literally pissed off
upgrading/downgrading kernels and doing shitty troubleshootings.
thanks a lot man . You literally saved my day.

regards,
Rohit

Nilesh's disabling of the i2c hid mod works. But on my hardware (dell xps 9333, i7) while fixing the TouchPad, this fix kills the touchscreen mouse input.
Less of 2 evils for now.

[Rodop (rodopee)]

The same problem on Lenovo Ideapad320 with kernel 4.15.0-72-generic #81-Ubuntu SMP Tue Nov 26 12:20:02 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux.

The problem didn't exist in previous kernel version.

[Ken Norris (ken-norris)]

Nilesh's fix worked for me thanks ... Ubuntu 16.04 Dell Inspiron 15 3000 series kernel 4.15.0-72-generic

[Damian Yerrick (tepples)]

I confirm that installing Linux 4.15.0.74 also fixes this issue.

sudo sh -c 'apt update && apt -y upgrade && reboot'

[Eugene Romero (anakondarh)]

Can confirm that kernel version 4.15.0.74 fixes issue for me as well.

[Albert Pool (albertpool)]

Yes, works fine.

I'll change the status to fix released.

[Albert Pool (albertpool)]

@Cliff Wong, your problem should be fixed as well. Please try the 4.15.0-74 kernel without any i8042 boot parameters to see whether you can use both your touchpad and touchscreen again.

[Gilles GAIDO (ggo)]

since last upgrade it works fine too : thanx a lot ! best regards

[Dave Jones (waveform)]

Are we sure this is fixed for Bionic? I've just installed 18.04.3 on an old Acer Travelmate B118; under the live USB the touchpad didn't work which sent me hunting around for bugs and eventually this one. After the installation concluded I found the touchpad still didn't work so I attempted Nilesh's workaround from #43, which was successful. The kernel version that's installed is the 5.3 HWE version.

Happy to open a separate bug if that's preferred but just thought I'd check here whether the HWE kernel is expected to include this fix too?

[Albert Pool (albertpool)]

@Dave Jones This issue is specific to 4.15: backporting a bugfix from a newer kernel to the 4.15 series went wrong because the commit depended on another one which was missing in 4.15. It's better to open a new bug if 5.3 has problems. They might be specific to your hardware.

(Also, a live medium might not have the newest kernel from the 5.3 HWE series. So please report your exact kernel version (use 'uname -r' in terminal) next time.)
