[Ubuntu-x-swat] [Bug 1887190] Re: MSFT Touchpad not working on Lenovo Legion-5 15ARH05
The solution has been found and should have been rather obvious in the first place... Just try a different distribution. I decided to try out Linux Mint 20.1 and have been testing it for the past ~6 hours, completely stock (except for all updates installed), no kernel modifications or GRUB options and it works every time on bootup with the touchpad. I am rather surprised that such a relatively old kernel (5.4) works with this new-ish laptop. Perhaps this was why I was so falsely focused on having newer kernels available in a distribution in the first place. I even tried 40 consecutive reboots whilst messing with the touchpad as the machine was booting and it still worked every time. Let it be known that the fix for the Lenovo IdeaPad 3 14ADA05 is to simply install Linux Mint. I have to imagine that other Ubuntu-based installs also work with this particular laptop, especially since it says "Fix Released" under Ubuntu and Ubuntu-related distributions. As far as Manjaro goes, also let it be known that something was introduced after Kernel 5.9.16-1 which breaks the ability for the touchpad to reliably work with this laptop. My best educated guess is that something is loaded too early or too late during bootup which gets jumbled up at random. No idea what that could possibly be, but I hope that Manjaro devs might take note. I know that at least @Helmut Stult might still be looking in this thread. I consider this fixed for my laptop :) -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-input-libinput in Ubuntu. https://bugs.launchpad.net/bugs/1887190 Title: MSFT Touchpad not working on Lenovo Legion-5 15ARH05 To manage notifications about this bug go to: https://bugs.launchpad.net/pop-os/+bug/1887190/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
[Ubuntu-x-swat] [Bug 1887190] Re: MSFT Touchpad not working on Lenovo Legion-5 15ARH05
Well, I spent the past few hours pouring over the entirety of this thread and I didn't try the patches to pinctrl-amd.c provided by @Helmut Stult in post #317. These were downloaded and placed in the same source directory as the other patches for Manjaro kernel 5.11.13-1 and lines were added to the PKGBUILD file for the patches. - 0303-pinctrl-amd2.patch fails to apply with error "Hunk #1 FAILED at 472". This is presumably because the code that the patch is trying to change is not present in 5.11.13-1, if I am right in my interpretation of it. - 0303-revert-pinctrl_amd_remove_debounce_filter_setting_in_IRQ_type_setting.patch - Successfully validates, applies and I was able to compile and install 5.11.13-1 and the kernel functions on bootup. However, this too did not resolve the issue. The touchpad failed on bootup in the expected 1-30 reboot range (Got to 9 reboots), just as if no patch were applied. I am out of ideas and need some help from an expert, @Coiby Xu. There is nothing else for me to try and I'm not a programmer so I don't know how to create a solution from scratch.

Hey there @Coiby Xu thank you, I think I understand what you mean, basically use your Github for this, standalone_i2c_hid, but copy the i2c drivers from the cloned Manjaro kernel 5.9.16-1 ../src/linux-5.9/drivers/hid/i2c-hid/ directory into the ../i2c-hid_standalone/ directory in your project (replacing all 3 source files without the Makefile), then compile it and replace the according module in my running system. Just as a reference, directly dropping in /lib/modules/5.9.16-1-MANJARO/kernel/drivers/hid/i2c-hid/i2c-hid.ko.xz into the respective 5.11.6-1-MANJARO ../i2c-hid/ directory, then running "mkinitcpio -P linux511" (to use the new module.. if this is how to do it?) does not work, in case anyone was wondering. Touchpad immediately froze on bootup. ** I was able to compile the Manjaro 5.9.16-1 source files into a module (on 5.11.6-1 using linux511-headers) using your provided Makefile and followed the instructions to copy the compiled module into the 5.11.6-1-MANJARO ../i2c-hid/ directory. Also added the GRUB options and ran "sudo update-grub". It functioned, but did not fix the issue. Froze after 2 reboots. I also tried compiling the Github project as it is, using the provided source files (on 5.11.6-1 using linux511-headers) and it spit out: ERROR: modpost "irq_to_desc" (in ../i2c-hid-standalone/i2c-hid.ko) undefined ! ../i2c-hid-standalone/Module.symvers Error 1 Also I wanted to point out in your README the instruction to append "i2c_hid.polling_mode=1" to GRUB_CMDLINE_LINUX. Shouldn't this be appended to GRUB_CMDLINE_LINUX_DEFAULT? I don't really know, I've just never seen the non-_DEFAULT line used before. In either case, produces same results. Thanks for all your help, it was worth a shot. Maybe your code needs to be updated for recent kernels? I am still trying to play with the idea of focusing on the pinctrl-amd.c driver, but really need some help with what to do with that driver. I am not sure the culprit is the i2c_hid driver, but rather this driver. Maybe I'm wrong, but it certainly is the next place to look...

I don't know what I was comparing before, but I was wrong. The pinctrl- amd.c drivers are different between the two kernels. Apologies. I wonder if just dropping in the 5.9 pinctrl-amd.c driver (+possibly other related needed ones?) into 5.10 (or later) would work? -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-input-libinput in Ubuntu. https://bugs.launchpad.net/bugs/1887190 Title: MSFT Touchpad not working on Lenovo Legion-5 15ARH05 To manage notifications about this bug go to: https://bugs.launchpad.net/pop-os/+bug/1887190/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
[Ubuntu-x-swat] [Bug 1887190] Re: MSFT Touchpad not working on Lenovo Legion-5 15ARH05
Since this is the main thread on the Internet about this issue, I suppose it is appropriate to post here even though I am using Manjaro. - This issue is non-present on a Thinkpad 3 14ADA05 with touchpad MSFT0001:00 06CB:CE2D on kernel 5.9.16-1 which uses i2c_hid. It is not elantech or designware (doesn't load the associated specific i2c drivers). Installing an entirely new keyboard panel with a new touchpad, essentially rebuilding the entire laptop does not address this issue. It is the same model touchpad for this specific laptop model even if you order a new one (unless I got bad luck of the draw). - The issue becomes present on kernel 5.10.23-1 (and previous versions of 5.10) up to 5.12rc3. Have not tried compiling 5.12rc5, but no reason to believe it would work. The touchpad will fail to be recognized and work on bootup between 1-30 reboots. I have tried many things such as different kernels and GRUB_CMDLINE_LINUX_DEFAULT options, yes even checking to set the kernel config option others are suggesting (Manjaro removed then reinstated the CONFIG_I2C_HID_ACPI=m option). I also tore apart kernels 5.9 and 5.10 to look at the pinctrl-amd.c driver and found that there was no difference between the two on these kernels, so it is something other than what https://launchpadlibrarian.net/500948605/0303-pinctrl-amd2.patch addresses since it works on the former kernel but not the latter. Also, the patch fails to apply on 5.12rc5. I don't really know how to compare the entire torn-apart kernels 5.9 and 5.10 to try and find what change(s) could possibly cause this bug. Hopefully someone else knows how to? Might be able to get somewhere if so... Other mods might be replacing the touchpad with a model not designed for the laptop, but I don't know where to start with that either. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-input-libinput in Ubuntu. https://bugs.launchpad.net/bugs/1887190 Title: MSFT Touchpad not working on Lenovo Legion-5 15ARH05 To manage notifications about this bug go to: https://bugs.launchpad.net/pop-os/+bug/1887190/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
