Hi, I am trying to turn off the screen after N seconds, but it didn't work. I know that this can be done on X like this (as explained in https://wiki.archlinux.org/index.php/Display_Power_Management_Signaling#Disabling_DPMS): xset dpms force off First I tried this: weston -i 3 --tty 3 and that didn't turn off the screen after 3 seconds. I know because I set the background. Then I tried Weston with this configuration: [core] shell=ivi-shell.so modules=ivi-controller.so idle-time=3 [ivi-shell] ivi-input-module=ivi-input-controller.so bkgnd-surface-id=1000 bkgnd-color=0xffff00ff [output] name=Unknown-1 transform=normal Again, the screen would not go off after 3 seconds. In the wayland mailing list, I was told that this may not be implemented. It works with "desktop-shell.so" So, what do I need to do to turn off the screen after N seconds? Or at least to turn off the screen? Mit freundlichen Grüßen i. A. Vladimir Jovic ifm ecomatic gmbh

Hello Vladimir, Can you verify that the feature is working with xdg shell. The handling of dpms is implemented in compositor-drm backend, from first look could not find anything in ivi-shell which will prevent setting of the dpms. There is a simple timer which will be updated with the idle_time value after every activity, it this time times out there should be a dpms_off event to drm.

Hi, Yes, it works. I just removed "weston.ini", and started the weston with weston --tty3 -i5 And the screen is turned off. But if I try with next weston.ini, then it doesn't work.

Hi Vladmir, Checked the code: not good news: we never implemented the idle_signal in the ivi-shell, therefore the dpms will never work here. the desktop shell is implementing a signal handler which will trigger the dpms off function (see [1]). We have done some internal protocol extension which will allow you to do the setting explicitly but this is not a good idea, before this can go upstream we need some way to protect the protocols and make them available only for "special" clients.

Hi, Thanks for the info. Do you have a branch, where it is possible to do? Are you willing to share patches? Why is it bad idea to use your extension? If not, where do I start to implement it?

Hi, Thank you very much :) It works, but I had to make one change: "struct weston_output" has no member variable "set_ctm". I use Weston 6.0, so I am not sure if it was removed or added. What is it supposed to do anyway? Also, your README doesn't explain how to build everything, that is why it took me a while. Do you have repository somewhere? I could add makefiles and program which turn the screen on and off. Are there plans to implement this in the master of IVI? My boss is very optimistic, and said if a big player pays enough, then this goes in :) Mit freundlichen Grüßen i. A.
