Thanks for your information.
My Weston comes from git and the version is 1.5.90.
I will try 1.5.0.

Sure. We could discuss this in E_DEVEL mail list. :)

Hi Yan,



What version of weston are you running?

We are running the 1.5.0 version from distro which is using old xdg-shell protocol, and it doesn't get crashes.

I'm guessing you are running the version from weston git?

If yes, then you have to run weston client from 1.5.0.

In weston git, xdg-shell protocol has been changed and this version is not released yet.

Changed xdg-shell protocol would be included next wayland/weston version 1.6 that will be released on Sep.

Enlightenment is going to support new xdg-shell protocol after releasing 1.6 wayland/weston.



BR,

Gwanglim



p.s. And I think this kind of discussion (upstream e / efl for wayland) would be better to move on the upstream enlightenment-devel mailing list. :)

Hi, Carsten,
         I tested Weston-simple-shm and get segment fault error.

what segfaulted? client or server?




         And from https://phab.enlightenment.org/w/wayland/elementarytest/, wayland_egl seems available? I could see the test report of wayland egl.

thats for client-side. enlightenment as a server doesnt yetr support drm (egl) client buffers



         I will tried elementary examples.
         Thanks

e compositor right now doesnt support drm (egl) client buffers. just shm. so shm clients should be ok. all elm apps can be either shm or egl wayland clients. other toolkits/apps - not sure.

Hi, All,
      Just I tried e_comp_wl based on README.wayland in Enlightenment upstream on my Fedora 20.
      We could run enlightenment by ./enlightenment_start and found wayland socket in /run/user/1000/e-yanwang at XXX. And some applications (e.g. calculator of Fedora 20 but terminal not) could run.
      But I couldn't run Weston sample application like Weston-simple-egl even if I change XDG_RUNTIMR_DIR from /run/user/1000 to /run/user/1000/e-yanwang at XXX. It reports the following:
weston-simple-egl: clients/simple-egl.c:151: init_egl: Assertion `ret == 1' failed.
Aborted (core dumped)
      It seems that EGL initialization is failed. May I miss some necessary steps?
      BTW, Weston could run and Weston-simple-egl could run on it rightly.
      Thanks.

Hi Yan,

We are trying to enable enlightenment wayland server and EFL for Tizen Common/mobile platform.
But now, we are working on upstream. https://git.enlightenment.org/core/enlightenment.git/
You can see current upstream enlightenment has no x dependency if it is building with wayland-only version.
We are going to merge it to tizen common when it is stable.

BR,
Gwanglim

Yan,

In Tizen 3 each platform may do what it wants when it come to the window manager but for most embedded system Weston/XDG might be enough.

So as my understanding, we won't port enlightenment to the later (Wayland./ Weston with XDG extensions ) platform. Right?

Yan,

we have two version of Common :
  - X based with Enlightenment
  - Wayland./ Weston with XDG extensions.

The later is the base for IVI and has no X at all (not even xwayland)
QT, efl and Ozone have been patches to integrate XDG support.

Hi,
         Thanks for your clarifying this about Tizen IVI. But for Tizen Common?
         I haven't tried e_comp_wl so far and could you please give me more detail of X legacy if possible?
Best regards,
Yan Wang

to be honest there is no plan to add enlightenment in IVI yet, and we do not see a strong pull from  the automotive community.
Furthermore as the current implementation still requires some X legacy than we do not want to see coming back in IVI, it unlikely to called by the IVI community in a short term.

But t is nice to see the progress.

Hi,
         Just read this page: https://phab.enlightenment.org/w/wayland/
         May there be a plan to enable enlightenment based on Wayland for Tizen Common/IVI platform so far?
         Thanks.
