[arch-general] How to set grub2 resolution to 1366x768

[Bill Sun]

Hi,

I want to have a 1366x768 resolution for grub2. Unfortunately, `vbeinfo`
shows that my computer doesn't support that resolution (up to
960x640/1024x768). So, can I load some additional modules for grub2 so
that it can support 1366x786 resolution in my computer?

I tried to do the following steps in grub2 command line:
    1) insmod 915resolution
    2) 915resolution 5c 1366 786
After step2, grub2 command line became completely black and
unresponsive. I had to press the power button to force halt my machine.

System information:
    Archlinux x86_64
    grub2-common 1.99
    grub2-bios 1.99
    Thinkpad X220 (with Intel Sandy Bridge CPU graphic card)
