I am also putting USE_X11 = “no” in sources/meta-fsl-arm/recipes-graphics/gpu-viv-bin-mx6q/gpu-viv-bin-mx6q.inc so framebuffer gpu drivers get included.

yes just before dora was released.
Thas was with oe-core + meta-oe + meta-fsl-arm and x11 removed from the
DISTRO FLAGS and opengl added to DISTRO FLAGS.
