Wayland and X11 on Yocto


Manuel Wagesreither
 

Hello all,

I'm building an image to run on various SBCs and would like to equip it with a graphical interface.

There are quite a few things very unclear to me. Can someone help me with that?

* Why is X11 enabled by setting an IMAGE_FEATURE (namely x11, x11-base or x11-sato), while Wayland is enabled by IMAGE_INSTALL only (weston-init and weston)?
* Theory: Is IMAGE_FEATURE +=x11 manipulating IMAGE_INSTALL under the hood so you don't have to do it manually? And as there is no IMAGE_FEATURE "wayland", you have do it manually. Correct?
* Why is Wayland different in that it doesn't need an IMAGE_FEATURE to enable it?
* Why does core-image-weston.bb need to enable IMAGE_FEATURE hwcodec, while core-image-x11.bb does not? (Dunfell branch.)

Thank you.
Regards, Manuel
