Is there any way to control the degree of dimming that occurs when
the NeXT screen dimmer kicks in? I know how to use Preferences to
control the amount of time that must expire before the screen automatically
dims and I know how to set the "active" screen brightness. What I
want is a way to control the brightness of the screen when the screen
is in the "inactive" mode. I'm not too keen on the idea of manually
dimming and brightening the screen whenever I'm going to be away from
the console for a while. Thanks for any info on this.

Along these lines, does anybody have a screen blanker that blanks the screen (to a specified darkness)? Anybody got anything which does stuff on the blanked screen that is not CPU intensive? That way, you know the machine is still on, but don't have to worry about burn-in.

On the same topic, I have asked before about whether anyone had gotten screensaver (found in the archives) to work (we haven't). I got one affirmative response but we still can't make it work and it behaves similarly under 2.0. If it worked, it would be a nice way to do screen blanking as it permits any postscript file to be used as the screen display (including just black).

I have gotten it to work under certain circumstances. The invokation of the program, that is launched from the boot processing ( ie. forked from within the processing of rc.local ), does not work. Killing the initial invokation and restarting the program in the backround works for as long as the invoking user remains logged in. However, as soon as that user logs out, the program ceases to work. I am confidant that the program is attempting to run one of its screensaver scripts because on my cube the screen will dim, momentarily, and then brightens ( just as it usually does when the program successfully starts a screensaver script ). However, nothing else happens, and this is actually worse that not using the screensaver system at all because screensaver brightens the screen to full before failing to fork the screensaver script and leaves the screen that way. - Max ------------------------------------------------------------------------------- William R.

How about giving pft a PostScript program of your liking? For example,
pft -f /NextLibrary/Images/Scene_movies/spotlight.movie/spotlight.script.ps -s
When you're done, press your interrupt character. Typically that's Control-c,
but you can find out with
stty all
Hope this is useful,

how about holding down your finger on the dim button for about 30 seconds.

You might enjoy doing this, but I have better things to do with my time (like respond to silly USENET posts :-). Seriously, if an application like ScreenSaver can be written (that works at least in a partial sense of the word), it shouldn't be too difficult to make the degree of automatic dimming that already occurs be adjustable. -- John Garnett University of Texas at Austin garnett@cs.utexas.edu Department of Computer Science Austin, Texas

mmm... is there anyway to dim the screen completely? It can not be
done with dim button. Also, it is kind annoying during the night.
I tried that screensaver and couldn't get it work either...

Wouldn't it Oh great. Now NeXT's will be just like all the people who do xlock on their Suns and have the fractal images drawing all over the place, driving the load up. Admittidly, it would be neato, but how would you do it? To store 5 minutes of video images would be a major pain to your disk -- You could plug a vcr in -- or better yet, a video camara that is taking live shots of a aquarium. Seems a bit ridculious to blow $4500 on NeXTdimention just to do that though :). -Vareck Bostrom bostrov@mist.cs.orst.edu

Since there has been a lot of traffic about how to dim the screen
completely & quickly, I thought I might as well post this little
hack (also appears in NUJ11).
Put the following code into a file, say /me/hacks/Blackforeground.
In Terminal (or Shell) type (or use an alias for):
pft -f /me/hacks/Blackforeground
(Note: full path name is required.)
To quit, use Cntl-D (to end the expect keyboard input).
