Hi Barton, Please find my answers embedded below.

The reason I am asking this is that we will probably be doing a PoC that has to be Intel based with Tizen as the IVI and I would like to pick the best horse there if that is possible. See below for more details on this but essentially I'd recommend you use the NDiS-166 (based on Sandy Bridge) or the VTC-7110 (both from Nexcom). Thanks, b From: Barton Shields [mailto:[email protected]] Sent: Tuesday, January 29, 2013 11:12 AM To: 'VanCutsem, Geoffroy'; 'Bartlomiej Jozwiak' Cc: 'Clark, Joel'; '[email protected]'; 'John Cain'; '[email protected]'; '[email protected]' Subject: RE: Wayland Display Management issue in Tizen Hello Geoffroy, When you say "That Tizen IVI branch is also in sustaining mode ... so .. is unlikely this would get fixed ...", I have three related questions then: 1) Is the specific branch you're referring to specific to NexCom? This is the Tizen IVI branch that is based on the Tizen 1.0 codebase, the latest preview of that codebase was released on Sept 18th (https://wiki.tizen.org/wiki/IVI/IVI_Sept_18,_2012_preview_update). The following Tizen IVI preview images were based on the 2.0alpha code. The Nexcom VTC-1xxx and other IVI systems that are based on the Intel Atom E6xx (aka Tunnel Creek) have a PowerVR-based graphics engine (based on a proprietary core technology) which required us to integrate the EMGD graphics drivers. The team developing these drivers are no longer providing and updating these for Tizen IVI 2.0alpha. Joel Clark explained most of this very mail in a previous thread that you can find here: https://lists.tizen.org/pipermail/ivi/2013-January/000307.html 2) Are there are other branches we may employ for NexCom that are better, or is that the only one? Unfortunately not for these Nexcom systems. We are currently using the Nexcom NDiS-166 (based on Sandy Bridge processors) and are evaluating the VTC-7110 (which is a hardened, more automotive-grade version of the NDiS). This is what I'd recommend you use moving forward. 3) It sounds like several Tizen IVI branches are in a sustaining mode; can you comment on the future of Tizen? Will it go the way of its predecessor, MeeGo (I asked that because this is what I have recently heard)? Not sure what you are referring to but the only IVI branch that's in sustaining mode is the one based on the Tizen 1.0 code. It's typical of versions to go in sustaining mode after some time (although what's less typical here is that we did not release a final version of it). What happened to that Sep 18 preview is by no means an indication of Tizen going away any time soon.

That gives me more confidence that it's the same issue I ran into with a developer here but unfortunately there is no easy workaround for it that I could find. That Tizen IVI branch is also in sustaining mode at the moment so it is unlikely this would get fixed even if you filed a bug against it.

Could you confirm which system (e.g. VTC-1000 or NDiS-166) you use and which preview version of Tizen IVI? Part of that stack is the Wayland Display Management library. There are two issues that we have failed to resolve ourselves, and they are: 1) The screen saver is fades after a fixed period of time and we cannot determine we would like to either disable this feature altogether, or at least change it to a much longer period of time before it goes to sleep. You should be able to configure this via weston.ini (under /root/.config/). Look for the [screensaver] section and the [locking] option (in [shell]) 2) When the system is initially powered on, the screen is not active until it is touched. This is extremely unhelpful when trying to use this system for a demo and like the prior issue, have not had any luck in figuring out how to disable it. I do recall something similar on VTC-1000 (i.e. using EMGD graphics drivers) but I'd have to look it up again to see if there was any workaround. Can you in the meantime confirm whether you are indeed using such platform? Can you provide any assistance in this area for us? If you could point us to the resolution of this that would be a great help.
