DPMS support for Permedia2-based cards

Getting a patch kit

The original Tru64 UNIX V4.0F and V5.0 have no capability of DPMS (Display Power Management Signalling) for Permedia2-based graphic cards such as PowerStorm 4D10T and ELSA GLoria Synergy. (I've got no information about V4.0G and V5.0A...)

In order to use DPMS, you need to replace the ``comet'' graphics drivers with new ones. The drivers supporting DPMS features are included in the following patch kits.

V4.0F	duv40fas0004-20000613.tar (or newer)
V5.0	t64v50as0003-20010221.tar (or newer)

Patch kits for Tru64 UNIX are available at:

• Software Patches (Compaq Services)
  • search patches

Configuring DPMS

Under Tru64 UNIX, the DPMS features are affected by the power management subsystem of the OS. You can see the current settings of the power management subsystem using ``sysconfig'' command.

  # sysconfig -q pwrmgr
  pwrmgr:
  default_pwrmgr_state = 1
  cpu_slowdown = 1
  disk_spindown = 0
  disk_dwell_time = 60
  graphics_powerdown = 1
  graphics_standby_dwell = 10
  graphics_suspend_dwell = 15
  graphics_off_dwell = 30

If you would like to set graphics_standby_dwell to 12 minuites, type:

  # sysconfig -r pwrmgr graphics_standby_dwell=12
