Display abschalten

[hammu]

siehe auch hier:
viewtopic.php?p=508731&hilit=display#p508731
Kennt inzwischen jemand eine Möglichkeit, das Display auszuschalten, wenn die Box im DeepStandby ist?
Sobald sie in diesen Zustand fährt, bleibt immer die Uhrzeit drin.

Die Box steht im Schlafzimmer und die aktuelle mechanische Lösung für den Nachtbetrieb ist nicht optimal

[mrvica]

das ist hardwaremässig so, probiere mal vor dem Herunterfahren irgendwas ins Display zu schreiben z.B. einen Punkt
echo . > /dev/dbox/oled0

[hammu]

Geht nicht

Code: Alles auswählen

root@gbtrio4k:~# echo . > /dev/dbox/oled0                                                    
-bash: /dev/dbox/oled0: No such file or directory

When I set
/proc/stb/fp/oled_brightness
to 0
display is off.
But after entering DeepStandby it returns to a fixed brightness.
Looks like a hardware-defined value and cannot be altered because the OS is not present in DeepStandby.

[Dima73]

cat /proc/stb/power/wol
disable or enable?

It seems that this is a feature of the drivers (showing time in deep standby mode).
What will happen if

echo enable >/proc/stb/power/wol
echo 0 > /proc/stb/fp/oled_brightness
poweroff

[hammu]

Display becomes dark.
After shutdown is completed display appears again showing clock.
