Touchpad stops working after reboot on Apollo Lake

[Giorgio Andronico]

===SRU Justification===
Hantick touchpad stops working after reboot.

[Fix]
Disable runtime power management for the touchpad.

[Test]
User confirmed it fixed the issue.
Some users reported it doesn't work for them, I'll ask them to file new
bugs for different touchpads.

[Regression Potential]
Low. Disable runtime power management doesn't affect devivce's
funtionality. In general desktop usage the graphical session opens the
touchpad HID device so the touchpad never get runtime suspended, so it
won't hurt power in this case.

===Original Bug Report===
On the Jumper EZBook 3 Pro (V4) laptop, using an Apollo Lake N3450 processor, if you install Ubuntu 17.10 (or less) with isorespin and use rEFInd as bootloader (this is the only way to get linux booting on this laptop) everything works out of the box, but after a reboot or two the touchpad stops working. Both in Ubuntu and Windows 10. The only way to restore functionality is to boot from usb key ubuntu 17.10 respined, or disassemble laptop and detach-reattach battery cable. This is mesg | grep i2c_hid:

There has to be a bug in the kernel. Any way to avoid this?

What are the Linux kernel versions in Antergos and Manjaro, respectively?

Trying it more. It started working in Manjaro too. Then booting back into windows then back to Manjaro it stopped working again. So don't know what to make of that. If I can get it to fail again, I'll post the dmesg log. Any other info you need?

Does cold boot instead of reboot have the same problem?

Always working touchpad >> Antergos kernel: Linux version 4.13.11-1-ARCH
Sometimes not working >> Manjaro kernel : Linux version 4.12.14-1-MANJARO
Attached are the dmesg logs for both.

[iBART (mogio)]

I tried Ubuntu 16.04 with 4.13.11 and it is not working.

[Brad (bbaker6212)]

FYI, the Manjaro dmesg log attached above was from a boot when the touchpad was NOT working.

[Brad (bbaker6212)]

@iBART, is that Ubuntu 16.04 w/4.13.11 with rEFInd? I'm booting through rEFInd installed on my SSD partion, with my Antergos installed on SSD and Manjaro installed on an external USB drive.

[iBART (mogio)]

Yes, without refind it doesn't boot, because of GRUB.

By the way: strange things are appening! back to the semi working 4.14.0-041400rc7 the touchpad is 100% dead; not clics nor movements.

[iBART (mogio)]

No, sorry, my bad. Too many kernels installed.

This is the dmesg (plus the kernel param kaihengfeng requested) of my ubuntu 16.04 installation with the 4.14.0-041400rc7 kernel. It has the trackpad working but not its left/right buttons.

After this kernel mainline release, the touchpad is not working at all.

partially working touchpad 4.14.0-041400rc7

This is the dmesg of my ubuntu 16.04 installation with the 4.14.0-041400rc7 kernel. It has the trackpad working but not its left/right buttons.

After this kernel mainline release, the touchpad is not working at all.

[Brad (bbaker6212)]

OK so it turns out I lied. It doesn't always work on Antergos either. It seems to happen randomly and how to get it working again is also a mystery. Resetting BIOS default does not restore it, and neither does booting into Windows - where it's not working there either. I unplugged both the power cable and the USB mouse then just kept restarting it until it mysteriously started working again.
Attached is the full dmesg logs for both working (YES) and not (NO). Here the pertinent parts:

If it means you have "fast boot" enabled in your BIOS you should disable that.

[bradleybaker (bradleybaker-linux-kernel-bugs)]

Mogio, see this patch. It looks related to your button click problem perhaps: https://patchwork.kernel.org/patch/10070339/

[mogio (mogio-linux-kernel-bugs)]

4.15 is a big no. Latest drm-intel-next 4.15 hasn't the touch-pad movement working. Rolled back to the 4.14...

[bradleybaker (bradleybaker-linux-kernel-bugs)]

@mogio a guy on the TT forum says that 4.15 did not work for him but rolling back to 4.14.3 did. I'm not sure but I think he's using Ubuntu. 4.14.3 has also been working for me without failure (so far). Manjaro just released 4.14.5 so I will be upgrading and testing that out soon.

Same problem here on Chuwi LapBook Air
touchpad showing as ALPS0001:00 0911:5288 Touchpad
tried kernels 4.14.14 through 4.15.1 including discussed patches and all no goor on Arch Linux.

I have magaed to bodge the touchpad to work by constantly removing and re-adding the driver using modprobe but on first suspend, if the touchpad is enabled, my system crashes.

Any news would be helpful.

[mogio (mogio-linux-kernel-bugs)]

just wait 4.16 and see if all hid patches fixed the issue.

[mogio (mogio-linux-kernel-bugs)]

Created attachment 274123
4.14, 4.15, 4.16... still not working.

From ubuntu mainline...

the last semi working touchpad (movements are ok, physical buttons are not working) is the drm-intel-next 4.14.0-997.201712022100. After this: kaput. :)

[Boris Urman (urmanbm)]

Hi, Hans/Kai-Heng Feng

I tried kernel from comment #187 on Chuwi Lapbook Air 14.1 with touchpad HID\ALPS0001. It doesn't work for me completely - neither trackpad nor buttons. Is there anyhow I can help troubleshoot this issue?

BTW. Hans, thank you for your support and answers in my previous question.

[Kai-Heng Feng (kaihengfeng)]

Boris,

Can you attach dmesg? Or even better, file a new bug since it may be a different issue.

[iBART (mogio)]

Would be nice having it on mainline. 😅

[Olaf (hein-jessen)]

Hello,

have a Telcast F7 should be also the Touchpad SYNA3602, but not working with Kernel 4.15035.
Does anyone know when the patch comes in the current Ubuntu kernel?

[elPraga (elpraga)]

Hello,

I've tried briefly this kernel: https://people.canonical.com/~khfeng/lp1728244-testing/ on the Chuwi Lapbook Air using the current Ubuntu 18.10 (not officially released yet). Touchpad was working, no right button, but I didn't know about the GnomeTweak hack mentioned above. @urmanbm use this kernel.

@kaihengfeng Is there a chance for your patches to be included in the official 18.10 kernel?

It would help a lot..

[elPraga (elpraga)]

I can now confirm that two finger scrolling is working, and tapping with two fingers works like a charm as the rightclick on Chuwi Lapbook Air.

[Boris Urman (urmanbm)]

Hi, Kai-Heng @kaihengfeng

Please find attached dmesg file. This is with kernel from comment #187. Should I file a new bug from it?

@elpraga, thank you. I wil try kernel from comment #162 and write back my testing results here.

[Boris Urman (urmanbm)]

@elpraga, @kaihengfeng

I can confirm that touchpad works perfectly with kernel from #162 on Chuwi Lapbook Air, Ubuntu 18.04. Please find attached dmesg for it.

Is there anyhow I can help further to resolve this issue?

[Kai-Heng Feng (kaihengfeng)]

Boris,

Does it work after S3?

[Boris Urman (urmanbm)]

Kai-Heng @kaihengfeng,

Kernel from #187 doesn't work after Suspend on Ubuntu 18.04.

[elPraga (elpraga)]

Hi Kai-Heng @kaihengfeng,

I can confirm that suspend works as expected under Ubuntu 18.10 using the kernel from comment #162.

[Mikhail (sul)]

Hello,

I've got Chuwi Lapbook Air and the touchpad doesn't work with Ubuntu 18.10 latest kernel v4.19, so the only one proper kernel for me it's the one from #162. Are those changes going to be included in the official Ubuntu's kernel someday?

[Kai-Heng Feng (kaihengfeng)]

The issue should be fixed by next Bionic kernel. Should be release at January.

[Kai-Heng Feng (kaihengfeng)]

Another Bionic back port here:
https://people.canonical.com/~khfeng/lp1728244/bionic/

Make sure the system gets coldboot (shutdown) before testing.

If this doesn't work, please file a new bug. Quite possibly the touchpad is different.

[Dawid Olesinski (dawidro)]

EZBook 3 Pro v4 Touchpad stil not working. I've tried kernels from comment #187 (v4.15.0-35) and comment #221 (v4.15.0-43.46) and both haven't worked. I have tried to reload modules for both kernels as well as suspending laptop. Nothing helps.
Kernel v4.14-rc7 from comment #3 works correct apart from hard buttons.

[Brad (bbaker6212)]

Try Manjaro with kernel 4.19.xx or LinuxMint latest. There have been various fixes for touchpad in newer kernels.

[Brad (bbaker6212)]

I don't know about LinuxMint but you can install Manjaro onto a USB destination drive and boot from that to test it out first/without touching your HDD/SD installation.

[Dawid Olesinski (dawidro)]

Linux Mint uses Ubuntu kernels so it won't work as I have tried newer kernels as well (I'm on Ubuntu 18.04) I haven't tried Manjaro but I have installed Arch free days ago and it didn't work. I guess I will have to stick to that kernel 4.14-rc7 for some time. I might give it a go with Manjaro tho.

[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-bionic' to 'verification-done-bionic'. If the problem still exists, change the tag 'verification-needed-bionic' to 'verification-failed-bionic'.

If verification is not done by 5 working days 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!

This bug was erroneously marked for verification in bionic; verification is not required and verification-needed-bionic is being removed.

[elPraga (elpraga)]

Has the fix been applied in Cosmic already?

I've just tried to install the proposed kernel (linux-4.18.0-16-generic), and the touchpad _is not_ working. I have to keep using the 4.17 kernel from this thread.

[Kai-Heng Feng (kaihengfeng)]

elPraga, please file a new bug report, thanks!

[You-Sheng Yang (vicamo)]

Landed to upstream as commit 807588ac92018, sru-ed to Bionic as 459448830a9b0 and Cosmic as commit 35e4595ea550f in bug 1801931. Disco or newer has it automatically.
