Hi Olivier, Do you know if the video drivers you have tested with (i915, vmwgfx, nouveau) were built-in or available as modules?

FYI, I finally got a picture ! All I needed to do was to use the magic "security=none". But of course, it's not very satisfying ; it should work without that. Please let me know if it works better with the new kernel patches. About the wayland-egl error message ("libEGL warning: wayland-egl: could not open /dev/dri/card0 (Permission denied)"), I think I understood what happens : - libwayland-egl is used by all wayland clients - libwayland-egl need to open /dev/dri/card0 - the wayland clients are run as user 'app' - /dev/dri/card0 is owned by group 'video' - user 'app' is not a member of group 'video' => denied access As a test, I tried to add the user "app" to group "video" (with "usermod -a -G video app"), but got a "PAM authentication failure". I don't know how to overcome this without recompiling the file system.

I've looked at the kernel used by the "Tizen on Yocto" today and found that it lacks quite a few patches that went into "Tizen IVI", in particular for the graphics drivers. I'm not sure whether these are relevant differences, but will test it once a build with a refreshed kernel recipe is done. Regarding the previous releases: I don't know whether any image really ever was tried on the VTC1010. -- Best Regards, Patrick Ohly The content of this message is my personal opinion only and although I am an employee of Intel, the statements I make here in no way represent Intel's position on the issue, nor am I authorized to speak on behalf of Intel on this matter.
