These days, if you enable udev a xorg.conf is often not needed.

Make sure to also enable the Intel graphics driver, i.e.
BR2_PACKAGE_XDRIVER_XF86_VIDEO_INTEL. Note that you need to switch the
"modular X.org server" variant to achieve that.

And then, start the X server by simply running "X".

Best regards,
