 Power management in Solaris 8

We leave our workstations in console mode by default,
with no windowing system running.  (Users then start
the windowing environment of their choice after logging
in at the console).

Under Solaris 7 and earier, it was possible to get power
management for the monitor working when there was
no windowing system running on the console.  The lines
in /etc/power.conf that controlled this behaviour

/dev/kbd                300
/dev/mouse              300
/dev/fb                 0 0             /dev/kbd /dev/mouse

This sent the monitor into reduced power mode after
5 minutes (300 seconds).

No matter what I try in power.conf under Solaris 8, I can't
get the same effect.  I realise that changes have been
introduced in 8, but I'd still like the old behaviour back.

(I'm also aware that the the old screenblank program
will blank out the screen, but unlike the power
management software, it can't set the monitor into
a reduced power mode)

Anyone know of any magic that can make this happen?

You can get that with dtlogin too, so there's no need for
tty consoles to get a different windowing environment.
(And the environment starts quicker if you use dtlogin)

This appears not to work anymnore (at least not on
cgsix type framebuffers)

The power.conf manual also states it is going away in future anyway.
(Seem it should still work)

Expressed in this posting are my opinions.  They are in no way related
to opinions held by my employer, Sun Microsystems.
Statements on Sun products included here are not gospel and may
be fiction rather than truth.

We've got an open fault call with Sun about it.  {*filter*} all happening,
though.  Seems all that Solaris 8 beta-testing didn't include systems
not running CDE.

Prior to Solaris 8, the cgsix driver had power-management support
perhaps a bit more complicated than some other frame buffer drivers,
to implement bright/dim on the Voyager.  That was ripped out in Solaris 8,
(not to mention a number of changes to the power management framework,
or so I conclude from the header files and from a couple of undocumented
ioctls that no longer work).  Perhaps when that was done, some other
aspects of the power management support in the cgsix driver got scrambled.
