Any change with updating the firmware through fwupd? Any known drivers added for this hardware in MXlinux?

    demm Any change with updating the firmware through fwupd?

    I did not do anything like that, shall I run that command ? is it safe ?

    demm Any known drivers added for this hardware in MXlinux?

    not that I remember - the touchpad was working in fresh install itself

    here are my results

    No updates for fwupd either 🙁
    Still looks mostly like a kernel change, any chance any of you can try and see if Linux 5.7 has any fixes/improvements?
    See the doc to install linux-next:

    Looks like Debian/Ubuntu patches the kernel for elantech:
    https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1700657

    Finding many links now for reports on this touchpad failing, examples:
    https://askubuntu.com/questions/1049787/lenovo-ideapad-330-touchpad-not-working/1052566#1052566
    https://bbs.archlinux.org/viewtopic.php?id=256002

    One thing I can try is adjusting the kernel config and disable CONFIG_I2C_SMBUS and CONFIG_MOUSE_PS2_ELANTECH_SMBUS, this will be done/tested in linux-next (next build, for 5.7.2).

    EDIT:
    One more fairly common recommendation is to add psmouse.elantech_smbus=0 to the kernel boot line (should have the same effect as rebuilding the kernel with the elantech entries disabled).

    Can any of you report back on the state of these touchpads using linux-next 5.7.2?

    It did not worked for me (neither solved the audio in the other tread until the sof-firmware solution). I reinstalled KaOS and I am in the same status of no Touchpad device recognized by the OS.

    I also think my computer has Elantech only to drive the trackpoint, but not the trackpad or Touchpad.

    On the other hand, checking from an Ubuntu installation where the touchpad worked, it reports these HID devices:

    That is so far the status

    So, is this with linux-next 5.7.2? Or psmouse.elantech_smbus=0 added to the kernel boot line?

    Please don't be confused by my previous post. I remind you that the previous lsmod and dmesg outputs were in Ubuntu, where the touchpad worked perfectly. Not in KaOS with the current kernel. Also, when I went to linux-next, it also did not worked.

    • demm replied to this.

      kamilomelo Also, when I went to linux-next, it also did not worked.

      Is it so hard to post exact outputs? 5.7.2 moved today, so there is no indication what you used. Your previous post just talks about didn't work, then post about Ubuntu, no logs, no dmesg, no answers about kernel version or boot lines used or anything related to KaOS. This issue can only be resolved if there is actual help, not more posts it didn't work or I also think my computer.
      Make sure to read asking and reporting the smart way.

      Yes, you are right, my bad...
      Here are some outputs using linux-next (5.7.2-1). No boot lines used:

      uname -r
      5.7.2-1-next

      Here the output of dmesg
      As observed, there is a mention of "hid" in that log, but not mention of "touchpad"
      [ 1.541755] hid: raw HID events driver (C) Jiri Kosina

      Now, here the output of journalctl
      It mentions a section for the initialization of "touchpad"

      Elantech -> "elan" is mentioned in both logs only related to the trackpoint, which is different to the trackpad or touchpad in Lenovo machines, which works without issues.

      Also the output of hwinfo:

      hwinfo --mouse

      Finally, here is the list of devices with libinput.

      Any other log or action you might find necessary?

      P.S. My intention copying the outputs of dmesg in another distro (Ubuntu) was to show how the missing device was displayed there. Maybe this give us a hint in how to handle this for KaOS. Apologies for the confusion.

      Line 1 of the DMESG:
      microcode: microcode updated early to revision 0xd6, date = 2020-04-23
      So you got the latest intel-ucode (one of the changes for linux-next 5.7.2), so newer firmware not available 🙁.

      thinkpad_acpi: Tablet mode switch found (type: GMMS), currently in laptop mode
      [    1.583516] thinkpad_acpi: This ThinkPad has standard ACPI backlight brightness control, supported by the ACPI video driver
      [    1.583516] thinkpad_acpi: Disabling thinkpad-acpi brightness events by default...

      Possible the above switch is blocking the touchpad? Is it a UEFI/BIOS switch or physical button you can push?
      For the rest no trace whatsoever in the journal or dmesg about a touchpad (just plasma is doing the standard kcm stuff, not hardware related).
      Does xinput list list anything about a touchpad?
      Any output for lsmod | grep hid or lsmod | grep i2c?

      As far as I know, there is no button/key that enable/disable the Touchpad in my machine (Lenovo X1C7). Only an UEFI/BIOS switch, which I deactivate and effectively disable the touchpad for other OS in the machine. I re-activate it, then the touchpad worked for the other OS, but not for KaOS.

      I am using "5.7.2-1-next" and here are the outputs you sugested

      xinput list

      hid                   131072  1 i2c_hid

      Since this change does not have any effect, I will revert it:
      https://github.com/KaOSx/core/commit/1397b8a3076504712f1da95a4e43c6e4573415fe#diff-c3823a713c080ad6e13a46a541231695L3733
      Could any of you test the last kernel known to work without issues for these touchpads? I uploaded on old 5.3 kernel for this (good to have linux-next installed, in case you have other issues booting with this kernel):

      sudo pacman -U https://sourceforge.net/projects/kaosx/files/packages/linux-5.3.8-1-x86_64.pkg.tar.xz

      and if you have linux-headers installed too:

      sudo pacman -U https://sourceforge.net/projects/kaosx/files/packages/linux-headers-5.3.8-1-x86_64.pkg.tar.xz

        demm Could any of you test the last kernel known to work without issues for these touchpads?

        In my case, a brand new Lenovo X1C7, I cannot see if the touchpad ever worked before in KaOS. I have only tested with kernels: 5.6.8-1 and 5.7.2-1, with results described in my posts before.

        As suggested, I tried the kernel 5.3.8-1 and the "xinput list" and the "lsmod" looking for "hid" and "i2c" were exactly the same as posted before using the linux-next 5.7.2-1.

        Here also the dmesg output in 5.3.8-1

        Once again, I boot in the same machine using Ubuntu and run "xinput" and "lsmod" to try to find the drivers/devices names and I got the following (hope this will be useful):

        It seems like these "hid-generic" and "hid-multitouch" drivers are related to the touchpad.

        Do you have xf86-input-synaptics installed in Ubuntu? Please test linux-next 5.72 again, with that package added.

          The package xf86-intput-synaptics doesn't exist in the Ubuntu repository. There were other "synaptics" package matches but none of them were installed in Ubuntu (yet the touchpad worked perfectly there).

          I tried KaOS linux-next 5.72 with the xf86-input-synaptics package added. Touchpad still not working. Even after hard rebooting the log outputs are the same as before

          Just to follow up with my previous answer...
          I have updated linux-next to the 5.7.4-1 and it remains the exact same outputs for xinput, dmesg and lsmod as I posted before for 5.7.2-1. The touchpad still not recognizable by KaOS.
