>From the log you provided, there is no touchpad i2c devices in /sys/bus/i2c/devices/
Please try this: "Another try is downloading ubuntu 22.04 installation image and create a usb installation media, boot with usb drive, select "try ubuntu without install", to see if the touchpad could work or not with it." If the touchpad with 22.04 installation media still doesn't work, I doubt it is the BIOS or BIOS setting issue. you need to check BIOS setting and upgrade the BIOS. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/2112220 Title: ASUS X555UB touchpad not detected on Ubuntu 24.04 with kernel 6.8.0-40-generic Status in linux package in Ubuntu: Incomplete Bug description: After upgrading to Ubuntu 24.04 with kernel `6.8.0-40-generic`, the touchpad of my ASUS X555UB laptop stopped working completely. ## What I observed: - `xinput list` only shows Xwayland pointers, no touchpad. - `libinput list-devices` (with sudo) does not show the touchpad at all. - `sudo dmesg | grep -iE "touchpad|i2c|hid"` returns no output, which suggests the device is not detected by the kernel. ## Additional information: - The touchpad is enabled in the BIOS. - It was working correctly in Ubuntu 22.04 and in previous kernel versions. - An external USB mouse works normally. - I'm running Ubuntu 24.04 (noble) with all updates installed. Please let me know if you need logs or extra information.
