keyboard-request(7) Miscellaneous Information Manual keyboard-request(7)NAME
keyboard-request - event signalling console press of Alt-UpArrow
SYNOPSIS
keyboard-request [ENV]...
DESCRIPTION
The keyboard-request event is generated by the Upstart init(8) daemon when the keyboard request key combination (typically Alt-UpArrow) is
pressed on the console.
The support for this event depends on your kernel configuration. Suggested use for this event includes spawning a new login console when
pressed, or for secure attention key support.
This event is not handled in the default Upstart configuration.
EXAMPLE
A task to be run on the keyboard request might use:
start on keyboard-request

XChangeKeyboardDevice - change which device is used as the X keyboard
SYNOPSIS
#include <X11/extensions/XInput.h>
Status XChangeKeyboardDevice( Display *display,
XDevice *device);
display
Specifies the connection to the X server.
device
Specifies the device to be used as the X keyboard.
DESCRIPTION
The XChangeKeyboardDevice request causes the server to use the
specified device as the X keyboard. The device must have been
previously opened by the requesting client via XOpenDevice or a
BadDevice error will result. The device must support input
class Keys, or a BadMatch error will result. If the server
implementation does not support using the requested device as
the X keyboard, a BadDevice error will result.
If the specified device is grabbed by another client,
AlreadyGrabbed is returned. If the specified device is frozen
by a grab on another device, GrabFrozen is returned. If the
request is successful, Success is returned.
If the request succeeds, a ChangeDeviceNotify event is sent to
all clients that have selected that event. A MappingNotify
event with request = MappingKeyboard is sent to all clients.
The specified device becomes the X keyboard and the old X
keyboard becomes accessible through the input extension
protocol requests.
XChangeKeyboardDevice can generate a BadDevice or a BadMatch
error.
DIAGNOSTICS
BadDevice
An invalid device was specified. The specified device
does not exist, has not been opened by this client via
XOpenInputDevice, or is already one of the core X device
(pointer or keyboard). This error may also occur if the
server implementation does not support using the
specified device as the X keyboard.
BadMatch
This error may occur if an XChangeKeyboardDevice request
was made specifying a device that has no keys.
