[gentoo-user] How to turn off the screen permanently

[gentoo-user] How to turn off the screen permanently

[Marcin Zwd]

Well, I've just upgraded my laptop. The old one has ati
radeon r250 graphics card.  On this card I can easily turn
off the screen using nice program "radeantool" of course
"xset dpms force off" worked as well. And "turn off" was
permanent.  It is worth to mention that I was using
x11-drivers/xf86-video-ati opensource drivers...  On the
other hand, the new laptop has nvidia (quadro 135) aboard
and now I'm using x11-drivers/nvidia-drivers-177.82.
Everything works fine except one tiny problem now if I turn
off the screen and backlight after a few seconds the
backlight is back on!

For example:

$ xset dpms 0 0 5

The screen is nicely turning off after 5 seconds but after
3-8 seconds the backlight is back on! Then, I notice that
this is the screensaver. So I tried again

$ xset s off
$ xset dpms 0 0 5

And now after about 10 seconds I have whole screen back on!
I even tried vbetool dpms off. By the way it is not working
smoothly for me, so manage little ugly hack

--- screenoff --------------------
#!/bin/bash
for ((i=0;i<256;i++)); do
        /usr/sbin/vbetool dpms off &
        sleep 0.5
        PID=`pidof vbetool`
        if [ -n "$PID" ]; then
                kill -9 $PID >/dev/null 2>&1
        else
                exit
        fi
done >/dev/null 2>&1

But even now screen is back on again!!!

I'm using gentoo stable (gnome)
 x11-base/xorg-server-1.3.0.0-r6
 x11-drivers/nvidia-drivers-177.82
without
 gnome-extra/gnome-screensaver


Thanks in advance for any suggestion

I notice that "very partial" solution for me is to switch to console
(alt+ctrl+f1)
and as a root run ./screenoff script. At least this works and I can use it
to lid.sh script, for example something like this

-----------
#open
screenon
chvt 7
# close
chvt 12
screenoff
-----------

Try following:
sleep 1 && xset dpms force off

Given you're using nvidia, if you just use the nvidia settings app,  
the graphical one, you can just disable the screen. But, that one's  
actually perminant, as in removing that screen from xorg.conf

Thanks, I tried that before as well. Besides the screen is turning off, however
just for a few seconds. My guess is that probably gnome or some other
apps is turning the screen back on.

So, it seems that only I have this kind of problem :(

I tried that, but is seems that I cannot disable the screen without some
other screen connected. So, for instance if I connect an external monitor,
then it would be possible. However connecting an external monitor is not
really an option for me.

Thanks,
Marcin

No, I have this problem, too. When I use 'xset dpms force off' for the 
first few times, it works (screen stays off). After that, it always 
turns back on.

It also didn't go away when I switched from XFCE to GNOME.

The problem has been there since I bought my notebook 1.5 years ago. I 
just live with it.

Thanks. At least I know that this is not something wrong with my configuration.
As I mention before this is a small problem and of course I can live
with it too, but
this is not a point. I often leave my notebook for a few hours to compile some
programs and simply it would be nice if the screen stays off during that time.
Moreover, if the lid is closed I expect that the screen stays off as well.
Fortunately, at least I have the simple solution with switching to the
console ...

Lately, I notice that when I go back to fluxbox then everything seems
to be fine. Apparently, this is the problem with GNOME or some other
apps. At this point I do not know exactly how the wake up of x11 works,
but I have a question. Is it possible to set (some) options (xorg.conf?) that
*only* upon receiving keyboard or mouse events the screen is back on?
