With fbdev-backend.so weston normally start. What graphics card is that, which radeon? Could you try setting these environment variables for Weston: export MESA_DEBUG=1 export EGL_LOG_LEVEL=debug export LIBGL_DEBUG=verbose That would tell us which radeon driver exactly loads. The kernel log does mention "r200", but I don't know if that can support GL ES 2.0. But if someone can say off-hand that this card won't support GL ES 2.0, then that would be the cause. Weston does not have a renderer that would support fixed-function GL. Then we could check if there is a way to make the error message better. I suppose 'glxinfo' output from X could give hints of the card capabilities, too. You could try with the weston command line argument --use-pixman, which gets you DRM KMS but without OpenGL.

Therefore Weston's gl-renderer cannot run on it, and you will be better off with Pixman-renderer.

The only thing left in this bug is to check if we can be more clear with the error message in Weston. PS. Never do 'grep' on a log or a program output unless asked to, otherwise you likely miss useful information.

I'm sorry. libEGL debug: the value (0x9) of attribute 0x3040 di not meet the criteria (0x4) To be honest it is repeated for 12 times. -- GitLab Migration Automatic Message -- This bug has been migrated to freedesktop.org's GitLab instance and has been closed from further activity.
