    Subject[PATCH] Input: i8042 - add noloop quirk for Acer P459-G2-M
    Date
    On the Acer P450-G2-M, after the user opens the laptop lid and the device
    resumes from S3 deep sleep, the screen remains dark for a few seconds.
    If the user presses a keyboard key while the screen is still dark, the
    mouse and keyboard stop functioning.

    To fix this bug, enable the noloop quirk.
