That's a little bit better description. You're starting GNOME Shell,
and the "Oh no!" messages is not from the X server but GNOME.

For trouble-shooting Plymouth try booting without "rhgb quiet" boot
parameters. You can remove them inside the GRUB boot menu.

Have you noticed the different kernel boot parameters?
Who added "inst.xdriver=vesa" to them? And why? Is it like that
since your F20? Do you need it?
https://wwoods.fedorapeople.org/doc/boot-options.html#_inst_xdriver

[    90.317] Kernel command line:
BOOT_IMAGE=/vmlinuz-4.0.4-301.fc22.i686+PAE

Compare with your attached Xorg.1.log.OK (from the live image):
