[SOLVED] Black Screen Upon Booting with UEFI

I just reinstalled Arch, by hand using the latest Arch iso (12 April 2012), so I could partition it with GPT and use efistub to bypass needing a separate bootloader. Arch definitely is installed and loads, as I can (without seeing) login as root and reboot my computer. I didn't have any issues loading the UEFI-enabled Arch iso, so I have no clue why this is happening, and would really appreciate it if anyone can provide some input. My computer is an X220 running the latest BIOS (1.28), and I only have Arch installed. Thanks in advance.

Also, the only kernel options I've set are

elevator=noop ro quiet

I had added i915 to my modules line in my mkinitcpio.conf, but removing it, re-making the kernel image, and copying the appropriate files made no difference.

Can you see the grub menu?

I am not using grub; I'm using the method to bypass needing a separate bootloader described here in post 51.

I don't see how the machine can boot if these are your only boot parameters. What about initrd= and root=?
Boot from the Arch ISO, load the efivars module and show the output of efibootmgr -v .

I should have said the only boot parameters I used not required for booting--I took it as a given that I set initrd and root . My initrd is set to

\arch\initramfs-linux.img

where UEFISYS is mounted at /boot/efi, and vmlinuz-linux.efi is in /boot/efi/arch; my root is set to

/dev/disk/by-label/ROOT

But never mind now; I reinstalled Arch again and it's working now!!! Must have made a mistake the first time, not positive where.
