Public bug reported:
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.
