From 71b0b96d1ced2ab5d0fe67963e112d50c15f38e7 Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Thu, 30 Oct 2014 10:15:54 +0100 Subject: [PATCH] keymap: Ignore brightness keys on Dell Inspiron 1520 to avoid double events On the Dell Inspiron 1520 both the atkbd and acpi-video input devices report an event for pressing the brightness up / down key-combos, resulting in user space seeing double events and increasing / decreasing the brightness 2 steps for each keypress. This hwdb snippet suppresses the atkbd events, making the Inspiron 1520 work like most modern laptops which emit brightness up / down events through acpi-video only.
