Screenblank monitor suspend

Unread post by endecotp » Tue May 24, 2016 9:16 pm

Has anyone got their monitor to suspend / power-off when the screen blanks?
Is there support for this in the hardware / kernel?

There is no proper DPMS implementation.
We need to study how to develop the DPMS drivers.

Maybe slightly off topic, is there a way to turn off the monitor using some interface in /sys or /proc? I tried echo 1 > /sys/class/graphics/fb0/blank, but it only blank the screen, the monitor is still on. I did not try the android system for C2, but I seem to remember on C1+ android can turn off screen and go to sleep, so I assume there is some implementation in the kernel.

There seems to no such implementation. We will check it later.
