SUMMARY: SUN Monitor Power Management & WinDD

From: Jason Keltz (
Date: Wed Mar 12 1997 - 12:26:56 CST

In my message on Monday March 10, I asked two questions:

1) Is there such a thing as power management for the monitor in the SUN world?
2) I was interested in hearing from people who used WinDD from Tektronix
   in their company.

As always with this list, I received numerous messages which were very
helpful. Thanks very much to the following people: (Edward C. Zimmermann) (William L. Hamlin) (Jeff Wasilko) (Rudi Schwieger) (David Fetrow) (Stuart Beck) (Matthew Stier) (Fletcher B. Cocquyt) (Robert Tommaselli) (Gary Connors) (Larry Williamson)
putsch@UICC.COM(Jeff Putsch) (Brian K. Stolp) (Karl E. Vogel) (Carlos Lorence) (John Justin Hough)

.... and any others who happen to mail me after I send out this summary.
(it's always bound to happen :)

1) Is there such a thing as power management for the monitor in the SUN world?

Yes! It's on the black and white CD entitled "Updates For SOLARIS
Operating Environment 2.5.1" in the SMCC directory. The CD also has some
other goodies including SyMON, and Online Validation Test Suite. The
power management works with sun4m and sun4u machines. Not only can it put
the monitor in "power saving" mode, but there's a whole system for
suspending and resuming your Sparcstation that I was unaware of. It's
actually quite fascinating. I installed the following packages from the

SUNWpmu Power Management binaries
SUNWcpr.m Suspend, Resume package (sun4m)
SUNWcpr.u Suspend, Resume package (sun4u)
SUNWpmr Power Management config file and rc script
SUNWpmow Power Management OW Utilities

There's a few other packages, but they didn't seem necessary. There's
also an AnswerBook on the CD, "Solaris 2.5.1 on Sun Hardware AnswerBook",
but it doesn't really mention what specific packages you need to install
for what machines.

After the installation, I ran "dtpower" and set the "power saving" mode time
for the monitor. I also turned off the "auto" shutdown. I certainly wouldn't
want these machines (in a lab setting) shutting down if they weren't used for
the default of 30 minutes :) The changes get written to the file

I tried it out, and it works great on a Sparc 10. I'll be adding it to
a lot more machines shortly. I'm told that this feature will probably be
built right into Solaris 2.6 (sounds like the dream OS so far :)

By the way, one interesting point - a number of people mentioned to me
that I could just use a screensaver that blacks out the screen. This is
actually what is currently in use, but this doesn't help because the
phosphor is still active as long as the monitor is on. If you use just a
screensaver on your SUN, and you have the time, and these packages, I
suggest giving them a try.

2) I was interested in hearing from people who used WinDD from Tektronix
   in their company.

There was lots of information here. From the responses I got, and from
spending a lot of time looking at various items on the web, it seems that
people who use WinDD are pretty satisfied with it. However, it seems like
you need to have a pretty hefty server with loads of memory to be able to
handle the processing. Finally, WinDD isn't cheap. I received a number
of suggestions for other packages as well.

Here are some of the responses that I received:

I hope you find this information helpful.
