When using the Linux Kernel's EFI Boot Loader stub, X11 1.18.3=
 fails to start.=20
Everything works fine when using GRUB as the boot loader.

The kernel is based on 4.4.15 (specifically, Ubuntu's 4.4.0-34 kernel.

Looking at dmesg shows some interesting differences regarding fb, which is =
why
I suspect the device isn't getting automatically detected:
