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.

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.

libEGL debug: the value (0x9) of attribute 0x3040 di not meet the criteria (0x4) To be honest it is repeated for 12 times.
