I've asked this first in comp.sys.linux.portable and did not get a solution.
So I asked in comp.sys.laptops and I wanted to see if the answer proposed
made any sense to those of you with more Linux experience than I. It's not a
big deal, but it is a PITA for my wife (who can also be a PITA... but that's
a different story!). You guys are my last resort because if you don't know,
ain't no one who knows... and we'll just live with it. (She is making a good
recovery and while she has much more 'on foot' mobility, she is still 'on
butt' a lot of the day and her computer card games help keep her spirits up.
Another 3 weeks (we pray) she'll be fully mobile and kickin' my ass! Been a
long summer.)

Is there such a thing as a default linux kenel 10 minute screen saver?

Thanks,
Al

Question
++++++++++++
I put Slackware 9.1 with KDE 3.1 on wife's new Toshiba A45 laptop. Works fine
except for one annoying thing. When she is playing a game where there is no
keyboard interaction (like Solitare), every 10-15 minutes the screen goes
black. You hit any key and it comes back up and all is OK. I think it has
something to do with the fact that the machine has not 'heard' a keystroke in
a while.

I do NOT have APM or ACPI loaded, nor does KDE have any of the power saving
'features' enabled. Also, there is no screen-saver set.

I tried xset -dpms but that did not work.

Anyone have any idea of what the hardware is doing? I don't think it is a
Linux thing... but I could be wrong.

Also, look at xscreensaver. To select the specific screensaver(s) that
you want to run, run 'xscreensaver-demo'

More info via the man page for xscreensaver.

I don't know what you're talking about, but no, there's no "Default"
screensaver that I know of. I think it's simple ACPI and/or APM in the
kernel.

No. This is a Slackware thing, not a kernel thing.

It is 15 minutes and it is at the top of rc.M. Disable by setting the
blank value to 0. I suggest you remark out the existing line and replace
it with
PATH/TO/setterm blank 0

Another poster gave you suggestions for a screensaver in X if you want a
screensaver. I read into your words that no screensaver at all would be
just dandy.

/etc/rc.d/rc.M

# Screen blanks after 15 minutes idle time.
/bin/setterm -blank 15

I will try it, but I'm not sure this is it because the screen goes dark after
15 minutes even if wife is using mouse (on card game). It all depends on how
the kernel defines "idle time." Does that mean mouse as well as keyboard? If
so, than this is is not the answer.

But worth a try. Who knows. I still think its a hardware thing.

This is good in that I never heard of the rc.M file (or the other letters as
well!)

Did you try the linux support site of Toshiba?

my old toshiba laptop had a blanking option in its hardware setup,
reachable at boot or with Fn-F<something>.

This did not work. I was hoping it would, but it had no effect. I put the
setterm command as well as
xset s noblank
xset s off
in a script and put the script name in rc.local. I was surprised as hell to
learn that the xset would not execute. Got error "Unable to open display
0:0". I thought root could open eveything. Live and learn. Anyway, I executed
them as a 'user' and they did not help either.

I thought it might be an X thing, that maybe SendCoreEvents was not part of
the Input Device section, but not the case.

There is battery BIOS setting that relates to power and display blanking, but
I have not messed with it. I guess that is the next step unless someone has a
better suggestion.

What mystifies me is that the machine only cares about keyboard input as the
factor to determine whether or not it is idle, and not the mouse. Very
strange.

Thanks anyway,

Al C.

Have you checked your BIOS? As another poster said, some BIOSes have
blanking/power saving options, so that could be the cause of your problem.
