Subject: [PATCH] keymap: Ignore brightness keys on Dell Inspiron 1520 to avoid
|
|
|
b397f2a |
double events
|
|
|
b397f2a |
|
|
|
b397f2a |
On the Dell Inspiron 1520 both the atkbd and acpi-video input devices report
|
|
|
b397f2a |
an event for pressing the brightness up / down key-combos, resulting in user
|
|
|
b397f2a |
space seeing double events and increasing / decreasing the brightness 2 steps
|
|
|
b397f2a |
for each keypress.
|
|
|
b397f2a |
|
|
|
b397f2a |
This hwdb snippet suppresses the atkbd events, making the Inspiron 1520 work
|
|
|
b397f2a |
like most modern laptops which emit brightness up / down events through
|
|
|
b397f2a |
acpi-video only.
