Closes #10924

Summary

  • Restore ASUS ASUP1206 I2C touchpad input after a failed s2idle resume.
  • Rebind only the affected HID device, leaving the ELAN9008 touchscreen untouched.

Changes

File Change
default/systemd/system-sleep/asus-touchpad-resume Rebind i2c-ASUP1206:00 during post resume so i2c_hid_acpi performs a fresh HID probe.

The workaround targets the resume failure observed on an ASUS Zenbook 14 UM3406KA, where i2c_hid_acpi returns -121 while restoring the touchpad power state.
