Investigation done by alkersan 
-----------------------------------

The touchpad of the Razer Blade 15 (2018) laptop is unresponsive after boot.

After shallow investigation of hardware identifiers, the touchpad seems to be present the USB and I2C buses.

The USB part is visible as a HID device and includes a mouse interface, but it probably handles just the keys of the laptop, including the keyboard, media/function buttons and RGB backlight programming.
The detailed output of lsusb is attached. It has an ID [1532:0233] where 1532 stands for Razer Inc. and 0233 is a yet unknown device. Similarly to 0232, which Openrazer project identifies as a keybard of the previous 2017 Blade laptop (https://github.com/openrazer/openrazer/blob/master/driver/razerkbd_driver.h#L143). Thus a USB HID part is probably out of interest for now.

The i2c interface is presumably responsible for the touch positioning. It's mentioned in the dmesg.log surrounded with the vdd supply and interrupt errors of the so called i2c-1A582000 device. The i2c bus tree and the i2cdetect output is attached.

Another interesting detail lies in the touchpad behavior in the Windows OS. The laptop is bundled with a plenty of drivers and is fully functional from the factory. But after the clean Windows installation - touchpad is unresponsive also. The required driver to enable the touchpad is an Intel Serial IO Driver (http://drivers.razersupport.com//index.php?_m=downloads&_a=viewdownload&downloaditemid=2878&nav=0,350,765,766). It's comprised of 4 parts: GPIO, I2C, SPI and UART. Only GPIO and I2C are required for the touchpad to become responsive without reboot (INF files of these drivers are attached). Right after installation Windows detects the touchpad as an I2C HID Device and HID-Complaint touch pad (the device manager screenshots are attached). Both devices has a id 1A58:2000, appeared previosly in the kernel log.

pin = 100
Comment 18 Andy Shevchenko 2018-07-02 23:12:17 UTC
This pin is configured by BIOS as GPIO direct interrupt to IOAPIC (SCI mode).
So, there is coupled GpioInt() and Interrupt() resources. If I read DSDT correctly the IRQ resource, which must be used, depends on the setting of some internal variable. My understanding that, since the pin is configured to generate SCI, the driver should respect BIOS settings.
Comment 19 Andy Shevchenko 2018-07-03 01:44:45 UTC
Okay, more investigation on the message "flag is output". It seems that in the driver we missed the fact of IRQ to pin translation in one case. That's why we are actually talking to hadrware pin 100 (ACPI 129) instead of pin 79 (ACPI 100). And that pin is indeed configured as output.

But I need to confirm this, because it's early morning and I even managed to send a patch to mailing list (related to this, but not fixing) with a completely wrong commit message. Need some sleep for sure.
Comment 20 Andy Shevchenko 2018-07-03 01:45:41 UTC
Take the bug as it seems to be related to our GPIO/pinctrl driver.
Comment 21 jamir 2018-07-03 01:59:53 UTC
Let me know if you need me to try out anything.
Comment 22 Andy Shevchenko 2018-07-03 23:50:25 UTC

> Let me know if you need me to try out anything.

Can you add to the top of gpiochip_lock_as_irq() the following hack and try to boot again (we need dmesg with 'ignore_loglevel' added to the kernel command line):

if (offset == 100)
 offset = 79;

the touchpad is still not functional I have attached the dmesg after the change.

The error code is different this time though -

Thanks, it looks like we missed to ask you to apply both
- patch from comment #22, AND
- patch from comment #26

together and try.

Sorry it takes more effort than we assumed.
Comment 29 jamir 2018-07-06 15:04:07 UTC
gpiochip_lock_as_irq() doesn't exist in gpiolib-acpi.c anymore on rc3. Do you know where this function moved to? I see a call from the gpiolib-acpi.
Comment 30 jamir 2018-07-06 15:07:35 UTC
found it I think its in gpiolib.c

dmesg with 22 and 26 - works

Wow, the touchpad is working!!!

Touchpad mouse movement functional.
Touchpad left mouse button functional.
Touchpad right mouse button functional.
Touchpad 2 finger scroll functional.
Touchpad tap to click, not functional, don't see a setting on gnome settings to enable that.
Comment 32 Andy Shevchenko 2018-07-06 22:47:17 UTC
There are two issues at once that’s why two hacks. But to see picture better, can you please attach cat /proc/interrupt output after just boot, and after a bit so events, like touching, doing some gestures?
Also attach a pins file again with driver loaded.

All above from _working_ case, thanks!
Comment 33 Joe DeVivo 2018-07-06 23:15:14 UTC
Can these patches be backported to 4.17 or are there other things in 4.18 that are necessary for the fix?

Comment 38 jamir 2018-07-07 00:48:45 UTC
More observations:

I see lockups sometimes when restarting just before X starts (I have seen it now 4 times). I have to hold the power button and reboot and then the next time it detects the touchpad fine.

When it is locks up I see "supply vdd not found, using dummy regulator" message.


When I enable wayland in GDM (custom.conf) and gnome shell I see the option "tap to click" and enabling it enables the tap to click. 

I was xorg for two reasons mutter/clutter caps the refresh rate to 60. and open broadcasting app doesn't record wayland composited desktop (shows black screen).
Comment 39 jamir 2018-07-07 02:48:52 UTC
one more data point.

The lockup only seems to occur when I reboot the laptop. If I shutdown and power it back on I've been able to successfully start the OS like 7 times in a row without lockup.
Comment 40 Mika Westerberg 2018-07-09 09:20:34 UTC
So I think the touchpad locking is most likely not related and for that you should file another bugzilla entry.

Regarding the touchpad interrupt via GPIO we have two issues:

  - BIOS has configured the pin incorrectly to be owned by ACPI. Regardless it 
    seems that we can just skip checking for that bit in Linux driver as well 
    because interrupts still work (we may want to log something to dmesg about 
    this, though).

  - We do not map hwirq correctly in gpiochip_lock_as_irq() when
    get_direction() is called.

We will work a proper fix for the two but it may take some time as I will be on vacation next 3 weeks.

Thanks for your patience! Now it's clear.

The translation patch has been sent to upstream today (we expect maintainer take it soon). The ACPI hack needs to be thought about a bit longer. We are waiting for some elaboration internally from other team.

Hello

Andy Shevchenko said in a thread on redhat bugtracker that this could maybe also the solution for my problem:

The Hardware is different:
ASUS GL703GE Laptop

if you need more data i will be pleased to submit logfiles or whatever needet. i could also open a teamviewer session or something like that if this helps resolving the problem on my hardware.

in windows and bios the touchpad works but not on linux, not on debian, not on fedora, not on ubuntu...

Provide the same set of data we asked from @jamir, i.e. gpio-ranges, pins, and /proc/interrupts files. 

Meanwhile try to apply just one patch @jamir attached in comment #48.

It’s under /sys/kernel/debug/pinctrl/INT3450:00/ There also most important one called pins. You need to mount debugged before looking for them.

Thanks, that is helpful.

Can you test another patch from comment #66 (on top of the one from comment #48) and share the

Yay, GREAT, Andy you're a Genius, the Touchpad is working :)

After Downloading Kernel 4.18.RC6, patching with https://bugzilla.kernel.org/attachment.cgi?id=277507&action=diff and https://bugzilla.kernel.org/attachment.cgi?id=277553&action=diff it's working.

-Tap to click works
-2 Finger scroll works (only Natural Scrolling, always on)
-2 Finger right click works
-left mouse button works
-right mouse button does not work but with 2 finger click it works
-Edge Scrolling does not work
-it disconects from time to time (rmmod -r hid-multitouch && modprobe hid-multitouch helps)

shall I test other patches and do you still need the outputs from Comment 67 (interrupts, iomem, ranges, pins?

Sorry it wasn't working from the day 1.

Nothing to test for now. There are three problems in your case and one of them doesn't clear yet (in a sense of root cause). That's, we are discussing internally and will come up with workaround / solution later on.

There are still some issues, I guess it are the same issues that are also on the GL503VS and maybe in a different part of the kernel (not sure):

Problems:
-random lockups
-disconnection (workaround rmmod && insmod hid-multitouch)
-the physical button (the whole touchpad) is not debounced, if you click once it does multiple clicks (workaround: use tap to click)

False Acused Problems:
-non-natural 2 finger scrolling works after reboot

Marc, this bug is solely about GPIO issue. As Mika stated in comment #40, please create another one, or find if it's already created against HID subsystem.

Check what @jamir has, it perhaps similar to what you are esperiencing.

This patch also fixes the touchscreen (and pen) and touchpad (only works after a hibernation) on the newly released hp zbook studio x360
Comment 78 Simon Detheridge 2018-08-08 23:01:23 UTC
I have an almost-identical problem with a Tong Fang GK5CN5Z laptop (branded as a PC Specialist Recoil II)

The symptoms appear very similar, but using the patches here the touchpad still does not work, although the error message changes.

I got a very similar "cannonlake-pinctrl" "pin x cannot be used as IRQ" message. I installed 4.18_rc8 and applied the patches here, but I now get a different error and the device still does not show up.

I see:
[    6.813578] usbhid 1-6:1.0: couldn't find an input interrupt endpoint
and
[   20.468857] i2c_hid i2c-UNIW0001:00: failed to reset device.
...

Can you attach /sys/kernel/debug/pinctrl/INT3450:00/pins for *patched* version?

P.S. For now it looks like the GPIO problem gone, but please attach the file to make us sure. If it's the case, you would need to create another bug regarding to HID device communication issue.

For me on Asus FX504 laptop with ELAN1200 touchpad tap to click doesn't work.
Comment 93 Mika Westerberg 2018-08-24 11:17:21 UTC
If your touchpad works in general (the device can be used somehow) and does not fail with "GPIO can't be used as IRQ" error, it is most probably not related to this bug. Please file a separate bug about it.
Comment 94 Jon 2018-08-26 13:31:54 UTC
@Simon: Thanks for the info, you did lots of hard work. I had a look on the other ticket too. I've never compiled by own kernel, so I have not tried the patch. 

I'm a bit surprised to see that we need a separate ticket for "Razer Blade 15" and "Recoil II" given that both of them are actually "Tong Fang GK5CN5". I also don't undertand why the above patch "works" on Razer does not on Recoil. That's my understanding from your messages, can you confirm?

If you do find a patch that more-or-less works for Recoil, please give me a shout. I'll try to test it on my side too. I just want to avoid compiling my own kernel given that I have no idea what I'm doing without expecting any positive outcome from that. On the other hand, if you want someone else to confirm something on a similar system, I'm more than happy to do it. Just be descriptive of what you want me to do. (I know how to code but never hacked the kernel)
Comment 95 Jon 2018-08-26 13:35:08 UTC
Also FYI, Razer says they are working into bringing a Linux Driver for the touchpad here: https://insider.razer.com/index.php?threads/razer-blade-15-ubuntu-18-04-trackpad-not-working.35999/#post-447134

Not sure what's the progress with that and whether this will cover not only Razers but any Tong Fang GK5CN5 based laptop. I would love an update if anyone from Razer is on the thread. Cheers! :)

I'm facing the same problem on a Recoil II which is a similar but not identical model to Razers' (both are based on TongFang models). 

@Simon: I also read your details on Bug #200787. The two problems seem related so I tried the patches listed here for the pinctrl module (did not recompile the entire kernel, just the module) but that did not work unfortunately. 

Shameless plug: I appreciate that debugging drivers is not the most pleasant coding exercise, so the hero who will solve the problem on the GK5CN5Z model can claim this bounty: https://www.bountysource.com/issues/62633122-touchpad-on-tong-fang-gk5cn5z It's not much but others are welcome to pitch in. :)
Comment 99 Amey 2018-09-02 14:49:26 UTC
@Mika Westerberg  Well that was a mistake on my part. I forgot to put 30-touchpad.conf for enabling tap to click. Hope the patch would improve a little to fix random disconnects and make it in mainline kernel.

the patch you wrote for me does not work on Kernel 4.19-rc2 anymore, so the touchpad does not work in kernel 4.19-rc2 because i can not apply https://bugzilla.kernel.org/attachment.cgi?id=277507&action=diff since someone has changed something in pinctrl-intel.c, so the patch works only with 4.18-rc6. my question is, this fix did not went into mainline?

with kind regards

To be clear, there are three patches, two of which are part of v4.19-rc1.
The only piece is missed in upstream is pin ownership check W/A, that is effectively is a middle of the attachment #277507 [details].

Hello Andy

i added now lines 1016, 1021 and 1022 from https://bugzilla.kernel.org/attachment.cgi?id=277507&action=diff to the /drivers/pinctrl/intel/pinctrl-intel.c from kernel 4.19-rc2 and now the touchpad works again, i guess if (intel_pad_acpi_mode(pctrl, pin)) evaluates to false and then it returns and does not do the rest of the function. But I'm not a C Coder, i know very little about C or Kernel things.

I will now test the things you said in thread and tell you the results in the thread https://bugzilla.kernel.org/show_bug.cgi?id=200663#c6

with kind regards

@Hieu Cao you could try the additional patch from Bug #200787 - if your touchpad is connected the same ways as mine then it could be the problem.

@trave5 yes, I managed to get it working, see above

I'm glad to hear this sound. Today I'll try to install a Linux again on my computer (I already remove it and replaced by windows). Does it work the same thing on virtual machine? Because I still not getting how to manage dual boot effectly.
Comment 108 Simon Detheridge 2018-09-17 12:05:16 UTC
@Hieu Cao - I don't know for sure that the patch will fix your problem in this case, I just figured it might be worth a shot. It may not be worth reformatting your computer for though.

You shouldn't need any of this stuff for Linux on a VM, as your hypervisor will be virtualising your mouse pointer anyway, so it won't be seeing the gpio directly.

Thank for your advice. I kinda love to use Arch and I3wm. It friendly but now I using the Windows it becomes harder for me, I can not do anything without mouse or touchpad. And the Cli on Windows it does not have a friendly command :(
I think I should waiting when this project is complete for a stable patch.

Hello Hieu

i can not tell for Fx504GD, for GL703GE you need to add these 3 lines from https://bugzilla.kernel.org/show_bug.cgi?id=199911#c102 i mentioned, otherwise the touchpad does not work at all...

if the Fx504GD has the same hardware as GL703GE then you have at least a functioning touchpad except that it crashes sometimes and then you need to rmmod and insmod hid-multitouch that it works again...

Try to kindly ask Andy Shevchenko he helped me to make my touchpad working. He Patched a lot, but this 3 lines i mentioned went not to mainline and without this 3 lines my touchpad does not work

with kind regards

I trying to install arch and patch it again, but now I got an error when try to patch it.
https://pastebin.com/1aRfSJy4
It look like the new kernel I download from kernel.org was add these patch.
What I need to do now?
Or these patch are not compatible with the newest kernel?

3 lines you said to add to the /drivers/pinctrl/intel/pinctrl-intel.c it already there.
Comment 115 Mika Westerberg 2018-09-18 10:31:46 UTC
You only need this workaround:

+#if 0
 	if (intel_pad_acpi_mode(pctrl, pin)) {
 		dev_warn(pctrl->dev, "pin %u cannot be used as IRQ\n", pin);
 		return -EPERM;
 	}
+#endif

if you see "pin x cannot be used as IRQ" in your dmesg. If there is no such message then the hack is not needed. I think someone in this bug mentioned that with new BIOS this particular issue went away so I'm assuming the new BIOS corrects the pin ownership from ACPI to driver.

Sorry but I'm still confuse. Does I need to patch 2 patch obove or just add only those code to the kernel source?
Comment 117 Mika Westerberg 2018-09-18 10:45:53 UTC
When you run "dmesg" command and there is a line saying something like "pin x cannot be used as IRQ" then you need to do the above hack. Otherwise it is not needed. Hope this makes it more clear :)
Comment 118 Mika Westerberg 2018-09-18 10:48:47 UTC
The other two patches are already included in v4.19-rc1 so there is no need to re-apply them (assuming you are running v4.19-rcX).

Comment 123 Mika Westerberg 2018-09-19 08:21:52 UTC
Hi,

Yes, the '+' should be deleted.

Could you try v4.19-rcX instead of v4.18.8 because it should include the two patches already. Then if you still see the "cannot be used as IRQ" error, you should apply the hack patch (otherwise it is not needed).
Comment 124 Hieu Cao 2018-09-19 14:35:39 UTC
I think I know what is my problem. May I patched the new kernel without any config except the name local and also I didn't install an xf86-input-libinput package. So that why my custom kernel kinda weird, it takes 4-5 minutes to compile, it worked not properly. Yesterday I have read the wiki page, and I realized that I can use the current config to a custom kernel's config: `zcat /procs/config.gz > .config. Then I compile it took more than 30 minutes (I guess because I slept). So after school, I will try to apply my custom kernel again. I hope it will detected my touchpad driver. If it still not detected, I'll try the newest kernel along your advice. Thanks
Comment 125 Hieu Cao 2018-09-19 21:20:23 UTC

its just a workaround

Comment 129 Simon Detheridge 2018-09-20 13:05:25 UTC
I'm not sure if this is better commented here or bug #200787...

With 4.19_rc4, plus my patch to fix the gpp-e pin numbers, I'm still getting:

cannonlake-pinctrl INT3450:00: pin 210 cannot be used as IRQ

@Mika Westerberg mentioned a new BIOS, but my manufacturer doesn't currently have a BIOS update available, so I currently still need the hack.

I wonder if there's another less hacky solution to this, given that I know pin 210 *can* be used as an IRQ, and I suspect that there will be a number of devices in the wild which don't have an updated BIOS that fixes the ACPI issue?
Comment 130 Vasilis Vryniotis 2018-09-20 13:26:48 UTC
Just wanted to echo Simon's point on this. 

Applying the fixes of this ticket + Simon's pin patch gets the touchpad working. BIOS update is not currently available, let alone that most manufacturers don't have Linux users in mind...

I would love to see a proper fix for that in the Kernel because compiling a custom kernel is quite difficult for the average user. I couldn't have done it myself without the help of Simon.
Comment 131 Mika Westerberg 2018-09-20 13:35:23 UTC
Yes, we are working on it. Sorry that it takes so long but we need to get the right people in Intel involved to confirm whether the assertion in the driver is correct or not. Once we know that we can decide what is the proper fix.

pinctrl-intel-Fix-pin-translation-when-requesting-IR.patch

Hi Mika,

I can confirm that your latest patch in comment #134 enables the touchpad of the HP Zbook mWS x360 that was buggy before. However, after applying the changes in the 'fixes' branch of the pinctrl tree, I realized that when requesting the IRQ, we are making twice the transposition from hwirq to pin.

I wrote a patch (attached) that fixes it, and I'd like to get your feedback before submitting it too.

With v4.19-rc4, the 2 patches that are on 'fixes' on pinctrl, and this one, the HP zbook I have here finally have both touchpad and touchscreen working without warnings in the dmesg.

(for references, the hwirq of the touchscreen is 77 that gets translatesd to 64, and the hwirq of the touchpad was around 250 and gets translated to 205 IIRC)
Comment 136 Mika Westerberg 2018-09-24 12:00:43 UTC
Hi Benjamin,

Hmm I don't see where we could do the translation twice. i2c-hid calls directly to irqchip so it should be using the non-translated numbers which then get translated in intel_gpio_irq_reqres() and the like to the appropriate pin numbers. Maybe I'm missing something.

Do you have possibility to add some debugging to the driver so that it prints out all the numbers (GPIO offset, hwirq and pin number)?

Also what is the error you are seeing after applying the last patch?

Thanks!
Comment 137 Mika Westerberg 2018-09-24 12:15:26 UTC
Actually you are right. The commit 55aedef50d4d810670916d9fce4a40d5da2079e7 ("pinctrl: intel: Do pin translation when lock IRQ") was added because gpiolib core calls ->get_direction() and that did not handle the translation properly. After the commit  96147db1e1dff83679e71ac92193cbcab761a14c ("pinctrl: intel: Do pin translation in other GPIO operations as well") we do translation so the previous commit is not needed and in fact it should not operate on pins in the first place (only with the GPIO numbers).

So I think the right fix for the issue you are seeing now is to revert 55aedef50d4d810670916d9fce4a40d5da2079e7 (basically your patch but also do the same for intel_gpio_irq_relres()).

I have put the backtrace in the attached dmesg:

- gpiochip_lock_as_irq()

Note that this only occurs for the touchscreen. The touchpad works fine, but if you look carefully at the logs, you'll see that the get_direction() gets called with pin 168 instead of 205 (with hwirq being 258).

So I guess here the touchpad works by luck because pin 168 is an actual GPIO while 51 is not.

I should have spotted that I was altering the behavior of this patch, indeed.

Just tested and I can confirm that reverting 55aedef50, adding your "pinctrl: intel: Do pin translation in other GPIO operations as well" and the patch in comment #134 works great on the HP.

Please do. I think it'll get faster this way. You can add my reported-and-tested-by on it (or anything similar that helps the process).

Hi Benjamin,

Can i ask which patch you apply to which kernel to get the HP 360 touchpad working? is it from comment #134 or #135 or both ? and 4.19.rc?

I want to give a try on my zbook studio G5, thank you

I have:
- v4.19-rc4
- 8e2aac333785f91ff74e219a1e78e6bdc1ef2c41 ("pinctrl: cannonlake: Fix gpio base for GPP-E")
- 96147db1e1dff83679e71ac92193cbcab761a14c ("pinctrl: intel: Do pin translation in other GPIO operations as well")
- the 2 patches from https://patchwork.ozlabs.org/project/linux-gpio/list/?series=67208

8e2aac33378 and 96147db1e1dff are in v4.19-rc5, so you basically only need the 2 patches from Mika that has been sent today.

> I want to give a try on my zbook studio G5, thank you

Cool, please report, I am also interested in the results.

Hi Benjamin and Mika,

Thanks for the information. I compiled 4.19-rc5 with the two patches. Unfortunately my touchpad is still not responding upon boot. I have a similar problem as Comment 77, namely the touchpad only works after a hibernation. i attach the dmesg

Bo, the 2 patches are now in v4.19-rc6.
According to your dmesg, you have the same pin number that I have on the x360. I am a little bit worried that it doesn't work for you.

Could you try booting a vanilla v4.19-rc6 and report if your touchpad is still failing?

Hi Benjamin,
I was on vacation and the laptop is no longer at my hand. Sorry I cannot test at this moment. Will report as long as i get the laptop back, which might take some time. thanks for the help.
Comment 152 janus.reith 2018-10-18 17:24:07 UTC
I am also trying to get the touchscreen working on my zBook x360.
The touchpad worked ootb with kernel 4.18.12, but I can't get the touchscreen to work and dont know where to get started.

On all kernel versions I tried I ran xinput --list and xinput test while using the touchscreen, without success.

Beside 4.18.12 (which shipped with Fedora 29 Beta) i tried the latest 4.19.0-0.rc8 unmodified kernel, and I tried compiling the latest stable 4.18.14 with the patch "pinctrl-intel-translation-fix.patch" that is attached on this bug, as Benjamin Tissoires and gschramm pointed out that this works.

Nothing of this seemed to have any effect, could someone give me a hint?

- It seems like some of these patches are obsolete, which of them would still be necessary on 4.19.0-0.rc8 ? Or, which kernel version with which patches applied can be confirmed to work to make the kernel recognize the touchscreen?

- Where else can I get started with debugging beside running xinput to see what fails, or if the touchscreen is recognized? Are there other relevant os/userspace
factors beside the kernel that I need to take into account?

I'd appreciate any help!
Comment 153 janus.reith 2018-10-18 19:17:28 UTC
Accordingly to comments 144-147 I compiled the kernel from v4.19-rc5 branch and applied the two patches that were attached by Mika 2018-09-25.

Contrary to what Bo posted in 148, my Touchpad still works as it used to do with the other kernels(except some 4.15 kernel that shipped with a latest ubuntu live stick I tried).

Touchscreen still doesn't work.
Comment 154 Mika Westerberg 2018-10-19 08:11:05 UTC
Hi Janus,

Do you still see the message "GPIO can't be used as IRQ" when you boot the system? If not, it may be another issue and in that case I suggest you to file a bug against input subsystem/HID instead.
Comment 155 janus.reith 2018-10-19 11:00:35 UTC
dmesg | grep -i "GPIO" does not return anything, neither does dmesg --level=err
I guess my issue is not directly related then.
Comment 156 Benjamin Tissoires 2018-10-19 12:00:39 UTC
Janus, IIRC, lat time I checked, CONFIG_PINCTRL_CANNONLAKE was not set in the default configuration of Fedora kernels. Can you double check?

If CONFIG_PINCTRL_CANNONLAKE is not set, the device will not show up at all in the dmesg.

This sounds like something which we need to fix in the Fedora kernels. Benjamin, can you ask the Fedora kernel team to enable this ?
Comment 158 janus.reith 2018-10-19 13:47:50 UTC
@Benjamin, That seems to be right, the config file includes the comment "# CONFIG_PINCTRL_CANNONLAKE is not set".

This is also the case for their latest 4.19-0-0.rc8 vanilla kernel they provide in the repos.

When compiling myself I took over that configuration. Will enable it and give feedback after compilation finished!

(Hope I'm not going beyond the scope of this bug too far)

No worries, it's better to understand why the fix is not working for you, and hopefully, the problem is just in the config file.
Comment 160 janus.reith 2018-10-19 14:43:06 UTC
Touchreen works now!

I built the kernel using the same setup I tried before, v4.19-rc5 with the two patches, now with CONFIG_PINCTRL_CANNONLAKE enabled.

I might be wrong, but it seems like the touchpad cursor speed seems to be faster? It already worked before, including multitouch gestures.

Just to clarify: If I compile the latest 4.19-0-0.rc8, will I still need the two patches?

That's possible. Haven't paid much attention to this as the test setup I have is not my primary machine.

IIRC, you should be good with a vanilla 4.19-rc8, yes. So no need for extra patches.
Comment 162 gschram 2018-10-19 15:07:11 UTC
I have compiled the 4.19-rc8 kernel today (using the mainline kernel package in Arch User Repository) on my HP ZBOOK G5 x360. And I can confirm the touchpad works way smoother (faster) now. This might be because libinput is now recognizing it, but I haven't been able to confirm this yet.
I didn't need any patches, so the touchscreen, pen and touchpad now work out of the box.

The only issue I still have is that GDM seems to have a problem starting with the new kernel (keep having a blinking cursor till I press the power button and then it goes to sleep, after sleep GDM works fine.

When I replaced GDM with Lightdm everything worked fine without going to sleep first.

Hello Hieu Cao

on my GL703GE it's not randomly but when you put the palm or 5 or more fingers on it.

i opened another bug but not assigned yet and i did not hear from any solution so far: https://bugzilla.kernel.org/show_bug.cgi?id=200663

It worked on v4.20 automatically. Few days ago, but I also uninstalled it either. Because the annoyning of disconnecting. I wonder if it fixed the disconnecting? I just want to make sure that to reinstall linux again.

in my case (Asus GL703GE) it does not. Disconnection Problem persists, but you can take now a 4.20 Kernal without patch and the Touchpad will work except if you put 5 Fingers or the Palm on it (on GL703GE)

This problem is not completely resolved: touchpad is not full functional after waking from suspend. This has been confirmed by multiple users as reported in #201175.
