Greetings,

We recently bought some Ultra 25 workstations for our student labs.
The prototype machines we had from last year came with XVR-100 cards.
Those machines are working as expected. The XVR-300 Ultra 25's mostly
work. But there are two quirks. One is that we have to install the
drivers by hand post install. I suspect this is due to the fact the
the guy who runs the jumpstart server is still using Solaris 10 U2. So
maybe if we used something newer like U6 this wouldn't be required?
For now I can install the drivers by hand. However... The screensaver
never turns on when gdm is displayed. (We disable dtlogin and enable
gdm) This only happens with the new XVR-300 cards.
The XVR-100 cards hooked up to sun monitors seem to go into power save
after like 10 or 20 minutes.

Does anyone know a way around this? I suspect its because the "xset"
program reports (xset q) that FBPM (Frame Buffer Power Management) is
disabled on this hardware. I'm worried all the sun monitors we bought
will burn in.

Thanks for any ideas anyone might have! I tried running xset +dpms as
root on the box in a cron job and it didn't work.

Perhaps the Jumpstart profile just isn't loading SUNWnfb, SUNWnfbcf,
and SUNWnfbw.

You mean that they come out of power saving mode, right? Oh yeah,
we've seen this. We had a ticket open with Sun on it, and it turns
out that they are working on a fix. But, we were able to figure
out a work-around.

Copy /usr/dt/config/Xsetup to /etc/dt/config/Xconfig. Append the
following line to /etc/dt/config/Xconfig:

$XDIR/xset s 600 0

Screen blanking will now work properly.

The default for the two timeouts is 600 seconds. What appears to be
happening is that the screen blanks properly at 600 seconds, but at
1200 seconds unblanks. The second timeout controls the "period to
change the background pattern to avoid burn in." When this timeout
occurs, the video is taken out of power saving mode by mistake. We
work around this by telling Xsun to never change the background.

The problem with this that root can't connect to the running X server
with the default configuration. This can be changed, but probably
shouldn't be.
