My question, as it comes from the title, related to grub, but it's a different thing.

I re-installed Windows 7 and Ubuntu 12.10 in UEFI mode (before that I was using normal BIOS) and everything went perfectly fine. Both systems load as they should but there is one thing that keeps bothering me. The problem is before I installed both systems in UEFI I used to boot in both system using common grub (non-uefi) and resolution in this grub was correct (which is 1366x768). Right now with grub-efi I have wrong resolution (which is seems to be 640x480).

So my question is can can I safely set grub-resolution using grub config files or issue is related to something else? (for instance graphics card).

I am using Ubuntu 12.10 Intel HD 3000 + Nvidia GT 540M Optimus (I am using bumblebee) Kernel 3.5.0-19-generic all updates installed! I also added ubuntu x-swat ppa for drivers.

Thank you for your help!
