Can I turn off DSI LCD?

Sat Oct 17, 2015 7:50 am

I bought Raspberry Pi 7 inch LCD which works with DSI interface.
It works pretty well.
What I want to ask is, can I turn off this LCD?(Or turn off backlight)

I tried disconnecting power from LCD to turn it off, but when I connect again, Pi reboots.(It looks like power problem.)
I also tried tvservice -o, it didn't work.

There's no way to turn it off for a while?

This is the most FAQ for the display. At the moment it's not possible. The RPF folks are working on changing the firmware to allow the backlight to be controlled from software.

There are already a few posts in here about that question. The latest message was that this feature should be available within the next week.

Can't wait for this feature to come out!

Is there a kind of changelog for each release I can see online?

Best regards,
Christian

The only "changelog" is the commit comments at: https://github.com/Hexxeh/rpi-firmware/commits/master

I also want to turn off the display by software. I can´t believe that such a basic feature is not implemented yet. :o

Yeah last week they said that it should be done IN the next week. That week has just started so it can still take a few days ;-)

Sure, the feature could arrive in the next 4 days. But let's be realistic, we are talking about programming stuff! There is still a chance that it might take a bit more time! :-D

Nice to have the voice of reason here! It will arrive when it's done.
