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)
Regards

Can you try
set gfxmode="1366x768;auto"
in grub.cfg?

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

Don't you expect at least something SVGA compatible as long as X isn't started?

Hi,
@Keshav P R: I tried: set gfxmode="1366x768;auto" It didn't give me a 1366x768 console; instead, grub2 just gave me a 1024x768 console.
@Thomas Courbon: Yes, I just tried the 'auto' parameter, and, indeed, it didn't change anything. I just update my BIOS to the latest version---1.2.6, and it didn't change anything. Maybe It's my BIOS's fault.
@Ralf Mardorf: According to `vbeinfo` under grub2, the maximum resolution my laptop (or my laptop's BIOS, I have no idea about this) supports is 1024x768. However, in Linux, I got a 1366x768 console by default (without further configuration). That's why I am thinking about insert some modules into grub2 and it may give me a proper console resolution.

I wasn't aware that there are commonly used non-standard resolutions available. http://en.wikipedia.org/wiki/VESA_BIOS_Extensions#Other_commonly_available_m...
Did you check by running "sudo hwinfo --framebuffer" too? It shouldn't differ, but perhaps there's something fishy with vbeinfo.

Maybe grub2 does not support non-standard modes. Better to ask in #grub irc.

My two grub2 correctly report and use non standard resolution. That is 1600x900 on my ux31e and 1920x1080 on my desktop.

Hi,
According your posts, should I file a bug report directly to lenovo?

Not to Lenovo. To grub2 upstream.

This whole thing is strange. I am running ubuntu/arch/win7 with grub2 and everything works perfectly. I am running an X220 as well with the intel sandy bridge. Is there a spot where this is set in my grub.cfg? If i could pinpoint this I can paste it here.

Look for the following line :
GRUB_GFXMODE=1024x768x32
in your grub.cfg (/etc/default/grub).
Also it would be nice if you could write down here the result of a vbeinfofrom the Grub2 command line.

Are you using `grub2-efi-*`? Currently I'm using `grub2-bios`. Maybe I can get correct resolution report if I switch to that `efi` version (though It does require some extra work)

The EFI version (using the efi_gop driver) is restricted to the same resolutions.
