All Intel IGPs made in more than the past two decades have depended on the i915
kernel device driver (module) for maximum Xorg performance since more than 15
years ago. Those older than about 2006 or so require the intel DDX[1] display
driver for Xorg (& Wayland?[4]). Newer ones can usually use either the intel DDX
display driver, or the newer technology modesetting DIX[2] driver, for maximum
performance in (either) X. All DDX drivers and the DIX driver depend on a loaded
hardware-specific kernel device driver that provides KMS[3] services.

[1] Device Dependent Xorg (display driver)
[2] Device Independent Xorg (Wayland; display driver)
[3] Kernel ModeSetting (Mode Setting)
[4] I have no idea whether Wayland is supported on older IGPs that require the
intel DDX.
