Hi @bertin !
You can check that the recipe that provides libxcomposite is in layers/openembedded-core/meta/recipes-graphics/xorg-lib/libxcomposite_0.4.4.bb:
$ bitbake libxcomposite -e | grep ^PROVIDES=
PROVIDES="libxcomposite xcomposite"
Do you have the meta layer listed on your bblayers.conf? Or, is it possible that your Yocto environment setup is not “healthy”?
Also, this is the link that @saijanani.tx wanted to share: How to add framebuffer EGL to console-trdx-image?
Best regards,
