Thread: Touchpad sometimes not detected

  1. #1

    Default Touchpad sometimes not detected

    I installed Opensuse Leap 15.2 on my notebook (Asus TUF Gaming FX505DY).
    Sometimes the touchpad is working, but sometimes it is not. in KDE System settings -> input devices -> touchpad "no touchpad detected" appears when the touchpad is not working.
    As this only happens randomly I don't know how to start resolving this issue. Sometimes a reboot helps.
    Previously I had Manjaro and Arch installed and there the touchpad worked all the time.

    As it worked always with arch and derivates i would think there is a problem with the kernel shipped with opensuse and my touchpad.

    IF the touchpad is NOT working there is no output with hwinfo --mouse,
    however if it is luckily working on the current session the output is:

    Code:
    46: PS/2 00.0: 10500 PS/2 Mouse

    I hope you can help me with this issue.

    I used to have that problem (back with openSUSE 11.3). It eventually solved itself.

    You might try adding the kernel repo
    Code:
    http://download.opensuse.org/repositories/Kernel:/stable/standard/
    and installing the newest kernel from there. It will have newer drivers, and those might work more reliably with your hardware.

    Examine the kernel messaging for the case where touchpad initialised and not...
    Code:
    dmesg | egrep -i "input|i8042|touch"
    Sometimes a kernel boot parameter is required to cope with hardware quirks. In particular, 'i8042.reset' might do the trick perhaps.

    FWIW, Ubuntu threads describing similar ASUS model and touchpad issues...

    Thank you for your help.
    I tried a newer kernel and then i realized i need some newer versions (e.g. glibc) than provided in Leap so i switched to Tumbleweed.
    Until now everything works fine.

    I will try that if it happens again.
