When building a core-image-x11 (for orangepi-plus using work in progress at https://github.com/O-Computers), without using meta-oe I get a working environment that includes xinit.  But after adding the meta-oe layer and just adding the glmark2 package to my image, the result is a non-functional X for lack of xinit, but with xserver-common which comes from meta-oe as well.

This naive patch produces a working image, but I guess there may be more things to adjust...
