Hi, I have a Sandy bridge based laptop (Asus Zenbook UX31e) and I use GRUB2 as my bootloader. I'm not at home and can't check that, but I didn't had to do any "insmod i915whatever" command line magic. I assume that you already tried to use the "auto" parameter instead of an hard-set resolution and that didn't change anything. I guess that your BIOS may not repport correctly the resolution supported by the X220 pannel. Is your BIOS up-to-date ? Cheers ! Thomas 2012/2/20 Bill Sun <cap.sensitive@gmail.com>
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)
