How to set native resolution in GRUB2 - Intel HD graphics

Hello.
I want to set 1440x900 in GRUB2.
I use Intel HD 3000 integrated graphics with CPU i5 2500k.
I use grub2-efi-x86_64 1:2.00beta4-1.

Hwinfo from running Arch Linux shows:

[root@myhost ~]# hwinfo --framebuffer
02: None 00.0: 11001 VESA Framebuffer

  SubVendor: "Intel(R) Sandybridge/Ivybridge Graphics Chipset Accelerated VGA BIOS"
  SubDevice:

  Mode 0x037f: 1440x900 (+5760), 24 bits
  Config Status: cfg=new, avail=yes, need=no, active=unknown

I tried these settings in /etc/default/grub:

GRUB_GFXMODE=auto #running with 800x600 resolution
GRUB_GFXMODE=1440x900x24 #not working: still running with 800x600 resolution

but always GRUB2 run with 800x600.

Any ideas how to set 1400x900 in GRUB2? Is it even possible?

Re: How to set native resolution in GRUB2 - Intel HD graphics

Did you try this workaround from the Grub2 Wiki?

https://wiki.archlinux.org/index.php/Gr … ution_hack

It seems to be the exact screen resolution you want, so in general I guess that it is possible.

Re: How to set native resolution in GRUB2 - Intel HD graphics

Thanks, I try invoke 915resolution from GRUB2 command shell, but GRUB2 had no such command.
How can I add 915resolution program to GRUB2 command shell?

Anyway I installed from AUR package 915resolution.
915resolution -l from running Arch Linux shows:

[root@myhost ~]# 915resolution -l
Intel 800/900 Series VBIOS Hack : version 0.5.3

Intel chipset detected.  However, 915resolution was unable to determine the chipset type.
Chipset Id: 1008086
Please report this problem to stomljen@yahoo.com

Any ideas?

Re: How to set native resolution in GRUB2 - Intel HD graphics

hwinfo shows your desired resolution, so it's in the vbios, which means you don't need i915resolution. That one is to program resolutions that are *not* in the vbios already.

But as to why grub2 won't work, idk, I'm staying away from this over-engineered piece of... something... that just happens to also include a bootloader smile. Could be your syntax is wrong. Have you already tried 1440x900@24 or 1440x900-24 or simply 1440x900 or 0x037f?

Edit: Gah, GRUB_GFXMODE isn't for grub.cfg, it's for /etc/default/grub. If you're configuring grub.cfg directly, it's 'set gfxmode=1440x900x24'. See what I mean with over-engineered piece of something? smile

Re: How to set native resolution in GRUB2 - Intel HD graphics

Yeah, I don't think you should be editing grub.cfg. Last time I used GRUB 2 that file had multiple references to the same thing.

Edit /etc/default/grub and then generate a grub.cfg:

$ sudo grub-mkconfig -o /boot/grub/grub.cfg

https://wiki.archlinux.org/index.php/GR … mmended.29

"How to Succeed with Linux"

I have made a personal commitment not to reply in topics that start with a lowercase letter. Proper grammar and punctuation is a sign of respect, and if you do not show any, you will NOT receive any help (at least not from me).

Thanks for tips. Yes, I edited /etc/default/grub not grub.cfg. Everytime when I finish editing /etc/default/grub I execute

grub-mkconfig -o /boot/grub/grub.cfg

I tried:

/etc/default/grub - GRUB_GFXMODE=1440x900@24  #aka 'set gfxmode=1440x900@24' in /boot/grub/grub.cfg - still running at 800x600

/etc/default/grub - GRUB_GFXMODE=0x037f       #aka 'set gfxmode=0x037f' in /boot/grub/grub.cfg - still running at 800x600

GRUB2 still running at 800x600. Any ideas?

Re: How to set native resolution in GRUB2 - Intel HD graphics

Oh god, my eyes, my eeeeeeeyesssssss!!!

Seriously, don't you guys cringe when you see that monstrosity?

I see you're using EFI, so why are you bothering with grub in the first place, just use efi_stub and rEFInd.

I use GRUB2 because GRUB2 is supported more or less by Arch Linux.
I think rEFIt is for Macs systems. I have ASUS P8Z68V-LX motherboard - http://www.asus.com/Motherboards/Intel_ … P8Z68V_LX/

I tried to install refit from AUR but without success because gnu-efi dependence shows build error.

I tried http://refit.sourceforge.net/doc/c1s5_burning.html but this CD don't work (not booting).

Re: How to set native resolution in GRUB2 - Intel HD graphics

I didin't say rEFIt. I said rEFInd. And instead of assuming, it'd do you good to inform yourself what it is and what it actually does. efi_stub + rEFInd is a much simpler way than using the grub2 monstrosity. Search the forums, there are threads discussing it.

In my humble opinion - grub2 is an OS looking for a decent boot-loader ... smile

Thanks! I installed rEFInd. I set resolution to 1440 900 but when rEFInd starts then showed me that there are to choose only three possibilities:
- 1024x768
- 800x600
- 640x480.
So I can't set 1440x900 resolution. sad

Re: How to set native resolution in GRUB2 - Intel HD graphics

No ideas then. hwinfo shows it, so it should be available. Though what hwinfo shows is the vbios, who knows if EFI is actually using that. It's quite possible that it's not, EFI has it's own graphics driver. And it seems 1024x768 is all you'll get from it. Unless someone more knowledgeable about EFI has some ideas.

Re: How to set native resolution in GRUB2 - Intel HD graphics

For grub2,

GRUB_GFXMODE="1440x900x32;1440x900x24;1024x768x32;1024x768x24;auto"

in /etc/default/grub is the correct syntax, not 1440x900@24 or the other ones. But even grub2 uses UEFI framebuffer driver. So if UEFI itself supports only 1024x768 or 800x600 , then grub2 will fallback to one of those resolutions.
