Hi Krystian, thanks for looking into this. I tried the workaround from the Arch thread (reloading i2c_hid_acpi/i2c_hid after loading pinctrl_amd), but it turns out pinctrl_amd is not available at all on this system — it's neither a loadable module nor built into the kernel:
$ grep pinctrl_amd /lib/modules/$(uname -r)/modules.builtin (no output) $ modprobe pinctrl_amd modprobe: FATAL: Module pinctrl_amd not found in directory /lib/modules/7.0.0-28-generic This is on kernel 7.0.0-28-generic (Ubuntu 26.04). Given the touchpad's ACPI device (ELAN0718) is I2C HID and needs GPIO interrupt routing via pinctrl_amd on this AMD Raven/Picasso platform, I suspect the kernel config for this release may be missing CONFIG_PINCTRL_AMD. I've run apport-collect 2161223 and attached a fresh dmesg log as requested. Let me know if there's anything else I can test. ** Attachment added: "dmesg_log.txt" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2161223/+attachment/5984660/+files/dmesg_log.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2161223 Title: Touchpad (ELAN0718) not working on HP Pavilion Gaming Laptop 15 with kernel 7.0.0 (Ubuntu 26.04) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2161223/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
