  • Touchpad not detected by kernel on ThinkPad X13 Gen5

    From =?ISO-8859-1?Q?S=E9bastien?= Villem@21:1/5 to All on Mon May 27 19:40:02 2024
    Hi,

    I recently bought a ThinkPad X13 Gen5 (benefiting from the discount
    generously offered by Lenovo to Debian Developers).

    The laptop runs Debian Bookworm, and I got almost all the hardware to
    work by using more recent kernel and firmware files (see Debian bug
    reports #1070647, #1070648, #1070650).

    However, I still can’t get the touchpad to work. It is apparently not recognized by the kernel, since the touchpad does not appear in /proc/bus/input/devices, and there is nothing in the kernel log. Note
    that the computer runs a custom build of Linux kernel 6.9.1.

    I opened a bug report against the kernel: https://bugzilla.kernel.org/show_bug.cgi?id=218868

    I’m largely ignorant of everything related to input drivers, so ideally
    I would need help to further debug this and provide more useful
    information to the kernel developers.

    Thanks,

    Actually, as pointed out privately to me by Mark Pearson, the problem
    is that CONFIG_PINCTRL_METEORLAKE was not enabled in my kernel
    configuration.

    This issue is tracked in Debian as #1072108.
