Hi koen,

Thanks for your comment.
I want to build an image only including directfb and gtk without x11. 
There are no any stuff related to x11 in this image. You know, directfb 
often is used in many embedded device because directfb is enough for 
their requirement. Perhaps they feel more familiar with directfb or gtk+ 
rather than x11. The purpose of building this image is for some people 
who  want to use yocto to develop their production getting  an image 
based on directfb anf gtk+ very easily.  So it need an mechanism making 
an mutual operation between directfb and x11 when compiling 
core-image-gtk-directfb for getting directfb image without x11. Of 
course, you can add directfb to DISTRO_FEATURES with x11, if you want to 
have both of them. But if you want to get an image without x11, then I 
think you can only remove x11 from DISTRO_FEATURES at current status 
because x11 is the default configuration.
>> x11 and directfb should be mutual in DISTRO_FEATURES. User may use file "meta-yocto/conf/local.conf.sample.extended" to select the mode they want to need.

So directfb and x11 can exist in the same image but not be defined in DISTRO_FEATURES at same time.

I know what you mean. It could be a good method to have both in an 
image. It may become a new task after completing  this feature.
