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
