atieventsd - ATI external events daemon
atieventsd [-a SOCKET] [-d] [-h] [-l FILE] [-m FILE] [--nodaemon]
[--nosyslog] [-s SOCKET] [-x SCRIPT]
The ATI External Events Daemon atieventsd is a user-level application
that monitors various system events such as ACPI or hotplug, then
notifies the driver via the X extensions interface that the event has
By default, atieventsd prints out logging information to the syslogd(8)
daemon facility unless --nosyslog is specified. The daemon is shut down
by sending a SIGTERM to the daemon process, for example, by killall
atieventsd. The various options are used to control daemon behaviour
and are explained below.
-a SOCKET, --acpidsocket=SOCKET
Connect to acpid(8) socket located at SOCKET instead of at the
default location /var/run/acpid.socket.
Output additional debugging information to the log.
Show a brief help message and exit.
-l FILE, --logfile=FILE
Output logging information to FILE. This output is independent
of syslog output thus logging to both syslogd(8) and this file
Run atieventsd in the foreground instead of running as a daemon.
Do not output log messages to syslogd(8). Normally used in
conjunction with --logfile above to redirect the daemon logging
-s SOCKET, --socket=SOCKET
Create atieventsd socket at SOCKET instead of at
/var/run/atieventsd.socket. This socket is used by aticonfig(1)
to send specific events to atieventsd.
-x SCRIPT, --xauthscript=SCRIPT
Use X authorization script at SCRIPT instead of at
/etc/ati/authatieventsd.sh. This script is used by atieventsd to
be granted authorization access to the X server display. See the
section below on the X authorization script for further details.
The daemon policies can be adjusted by aticonfig(1) with the use of the
--set-policy=STRING option to that command tool, where STRING can be
one of the following values.
Enable monitoring of laptop lid open/close events.
Do not monitor of laptop lid open/close events.
X AUTHORIZATION SCRIPT
The X authorization script provides a distro-neutral way for the daemon
to gain access to the necessary X server display in order to send it
commands. The script is located at /etc/ati/authatieventsd.sh unless
overridden by the use of the --xauthscript keyword above. The script
takes three parameters:
The first parameter is either the keyword "grant" to grant access or
"revoke" to revoke access.
The second parameter is the display number that the daemon is trying to
get authorization for, e.g., ":0".
The third parameter is the name of the X authorization file that the
daemon is using, as obtained from XauFileName(3x). This file is where
the authorization needs to be given. Note that this parameter only
makes sense if xauth(1) is being used. If another mechanism such as
xhost(1) is being used it can be ignored. If no form of authorization
is being done, the script can simply return 0 and the daemon will
assume that it is always authorized.
The return code from the script should be zero if authorization was
successfully granted or revoked, and nonzero if an error occurred.
