I run kodi-rpi on arch ARM (linux-rpi, aarch64) on a RPi4.

On HDMI 0 a monitor is connected, on HDMI 1 an audio system. I tend to listen to music for hours and since the monitor consumes a lot of power I want to toggle it off/on using a script mapped to a key on my remote.

When using fkms I use vcgencmd display_power 0/1 2 for that (0 = off, 1 = on). When using kms the vcgencmd doesn't work anymore, but kodi has the option of putting the monitor to sleep after 5 mins or more when idle under system power saving, and that also works with kms.

How does kodi do that? How can I use that in a script?

CEC

Disable the use of CEC in Kodi and use the cec cmdline tool cec-client for your script

I went to Settings > System > Input > Peripherals > CEC Adapter and disabled it. I rebooted the Pi just to be sure. Kodi is now started with CEC disabled. I'm not familiar with CEC and I also I don't know if my monitor supports it, its an old model but Kodi power save does put it in supsend after 5 minutes. When I login via SSH I tried the following:

Code:


[user@PC19 ~]$ cec-client -l
libCEC version: 6.0.2,  compiled on 2021-02-20 17:53:55 by builduser on Linux 5.1.16-1-ARCH (aarch64), features: P8_USB, DRM, P8_detect, randr, Linux

Any ideas?

Any ideas?

using a search engine instead of a forum i found this - https://www.endpointdev.com/blog/2012/11...mi-devices

"cec-client -l" does not show any devices. That's because my monitor does not support CEC (found that in the documentation). So my question still remains: how does kodi power saving option works? I need to put my monitor to sleep (supsend) using a script.

@jepsizofye , I appriciate your efforts but I'm afraid you misunderstood my first post. I'm running kms and kodi-rpi standalone, no X or other OS involved.

clearly...

i found kodi-rpi and it makes it look like its on archlinux but you say there is no linux involved so i cannot help as i dont understand what you have installed

[unformatted]

I didn't say there's no linux involved, just as I wrote in my first post: "I run kodi-rpi on arch ARM (linux-rpi, aarch64) on a RPi4.". So that's an Arch ARM install running the linux-rpi kernel. The boot configuration file contains "dtoverlay=vc4-kms-v3d", so it's using KMS. There's no GUI installed, only kodi-rpi, which is a stand-alone version.
