|

default y

default n
|

---help---
|
||||
Enables hot key handling over the input layer by default. If unset,
|
||||
the driver does not enable any hot key handling by default, and also
|
||||
starts up with a mostly empty keymap.
|
||||
This option enables thinkpad-acpi hot key handling over the input
|
||||
layer at driver load time. When it is unset, the driver does not
|
||||
enable hot key handling by default, and also starts up with a mostly
|
||||
empty keymap.
|
||||
|
||||
If you are not sure, say Y here. Say N to retain the deprecated
|
||||
behavior of ibm-acpi, and thinkpad-acpi for kernels up to 2.6.21.
|
||||
This option should be enabled if you have a new enough HAL or other
|
||||
userspace support that properly handles the thinkpad-acpi event
|
||||
device. It auto-tunes the hot key support to those reported by the
|
||||
firmware and enables it automatically.
|
||||
|
||||
If unsure, say N here to retain the old behaviour of ibm-acpi, and
|
||||
thinkpad-acpi up to kernel 2.6.21: userspace will have to enable and
|
||||
set up the thinkpad-acpi hot key handling using the sysfs interace
|
||||
after loading the driver.
