The same for the fallback "fbdev/fbdevhw" because it could not find a framebuffer.  Finally, it settles on "int10", makes a call into BIOS to initialize the GPU display as VESA with extensions VBE.  Next it starts to configure other associated devices/components, ie, events, kb, touch screen, camera, etc., & hands over to udev control of HDMI/DP & HD audio/digital because it couldn't find any drivers.

definitely not VESA.

Set that in xorg.conf and you should have full access to all
