SYNOPSIS
/usr/openwin/bin/sys-suspend [ fnxh ] [ d <displayname> ]
AVAILABILITY

DESCRIPTIONsys-suspend(1M) provides options to suspend or shutdown the whole sys‐
tem.
A system may be suspended to conserve power or to prepare the system
for transport. The suspend should not be used when performing any hard‐
ware reconfiguration or replacement.
In case of suspend, the current system state will be preserved until a
resume operation is performed (the next power on).
On a resume in the windows environment, the system brings up lockscreen
to ensure that only the authorized person has access to the system. In
a non-windows environment, the user will be prompted for password.
It is possible that when devices or processes are performing critical
or time sensitive operations (such as real time operations) the system
may fail to suspend. When this occurs, the system will remain in its
current running state. Messages reporting the failure will be dis‐
played on the console. Once the system is successfully suspended, the
resume operation will always succeed barring external influences such
as hardware reconfiguration or the like.
In case of shutdown, rc0 scripts are run, processes are killed, pending
data is written to the disks, and system is turned off.
OPTIONS-f Force suspend. This should be used with care. Using this option
causes the system to force all processes to stop. This option
should not be used during unattended operations.
-n Disable selection. This flag disables the selection popup dia‐
log at the invocation time.
-x Disable lockscreen. This flag disables the execution of
lockscreen at resume time.
-h Change the default from suspend to shutdown.
-d <displayname>
Connect to the X server specified by displayname. Format of
displayname has been described in X11(7).
FILES
/etc/default/sys-suspend file for setting a default value for the PERMS
variable. PERMS determines who are allowed to
use this command. Allowed values are:
all any user can use this command

this command
<user1, user2, etc.> a user in this user list or super-
user can use this command
console-owner a user who owns the system console

NOTES
Lockscreen on resume can be disabled by default. The following line
needs to be added to the user's .Xdefaults or .OWdefaults file:
Syssuspend*xlock: False
If xlock(1) is used for lockscreen functionality, its mode defaults to
life. This can be changed by adding the following line to the user's
.Xdefaults or .OWdefaults file:
Syssuspend*xlockmode: <xlockmode>
