To change the power management values that take effect every time you
restart the kernel, you create a file in stanza file format. See stanza
(4) for
more information. The stanza-formatted file can contain the following
power management attributes:
• default_pwrmgr_state
The global power management state. Specify 1 to enable or 0 to disable
this attribute.
• cpu_slowdown
The current state of CPU slowdown. Specify 1 to enable or 0 to disable
this attribute.
• disk_dwell_time
The default dwell time, in minutes, for registered disks.
• disk_spindown
The current state of disk spindown. Specify 1 to enable or 0 to disable
this attribute.
• graphics_powerdown
The current state of graphics powerdown. Specify 1 to enable or 0 to
disable this attribute.
• graphics_standby_dwell
The default dwell time, in minutes, for standby Display power
management Signaling (DPMS) mode. Specify a value of 0 to disable
this attribute.
• graphics_suspend_dwell
The default dwell time, in minutes, for suspend DPMS mode. Specify 0
to disable this attribute or specify a value greater than or equal to the
value for graphics_standby_dwell.
• graphics_off_dwell
The default dwell time, in minutes, for off DPMS mode. Specify 0 to
disable this attribute or specify a value greater than or equal to the
values for graphics_standby_dwell and
graphics_suspend_dwell.
For example, you can create a stanza file called power_mgr.stanza that
defines the following values for the attributes:
pwrmgr:
default_pwrmgr_state=1
