Hi Validimir I think nobody answered this, from what I can see. I'm forwarding to the layer-management mailing list which might reach the right people. Maybe since it was a long time ago, let everyone know if you figured this out already.

Date: Fri, 28 Sep 2018 07:26:01 +0000 Hi I started recently with ivi. I managed to create not so simple example, and it almost works. So, I start my example, it creates a layer, then wl and ivi surfaces, set source and destination dimentions for both layer and surface, set opacity, set order and then show both. And then it gets stuck. This is what getting scene outputs: root@pdm3:/home# LayerManagerControl get scene screen 0 (0x0) --------------------------------------- - connector name: Unknown-1 - resolution: x=1280, y=480 - layer render order: 1502(0x5de), layer 1502 (0x5de) --------------------------------------- - destination region: x=0, y=0, w=1280, h=480 - source region: x=0, y=0, w=1280, h=480 - opacity: 0.5 - visibility: 1 - surface render order: 50(0x32), - on screen: 0(0x0) surface 50 (0x32) --------------------------------------- - created by pid: 21067 - original size: x=800, y=600 - destination region: x=0, y=0, w=800, h=600 - source region: x=0, y=0, w=800, h=600 - opacity: 0.898438 - visibility: 1 - frame counter: 1 - on layer: 1502(0x5de) Take a note that the "frame counter" does not go above 1. Now, if I do this: LayerManagerControl set layer 1502 render order 50 or this: LayerManagerControl set surface 50 destination region 0 0 600 400 then it starts showing what is being rendered, and the frame counter starts going up. I tried looking into the source code for LayerManagerControl, but it revealed nothing to explain this behaviour. The sequence for ivi application (https://at.projects.genivi.org/wiki/displa y/PROJ/Wayland+IVI+Extension+Design#WaylandIVIExtensionDesign- SequenceforiviapplicationandHMIcentralController) tells nothing about specifically unpausing rendering starting. So, can anyone explain why is the counting not going up? Do I somehow need to start the ivi application? I see no ivi function to do anything like that.

Hi Vladimir, Looks like some timing problem, You could try to use the "layer-add-surfaces" binary which acts as minimalistic HMI controller and will create a layer and set the dimensions and so on. Just 1. strart Weston 2. start layer-add-surfaces 1 1 & 3. start your application And also please share which version of Weston and wayland-ivi-extension are you using Best regards Eugen Friedrich Engineering Software Base (ADITG/ESB) Tel. +49 5121 49 6921 > -----Original Message----- > From: genivi-ivi-layer-management <genivi-ivi-layer-management- > bounces@lists.genivi.org> On Behalf Of Gunnar GMail > Sent: Montag, 5.
