[SOLVED] The 773 vga mode?

Arch supports FrameBuffer mode and a 1024 x 768 display for my video card (Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller). However whenever I try to compile the kernel from source (basically to disable modules I do not need and also to change the boot logo) I end up getting either a blank screen while boot-up or a message saying the 773 video resolution is not supported.

Specifically I get a resolution not supported error (expectedly I guess) when I compile the kernel without making any changes in menuconfig. However even then all the difference there is is in the console mode; once I start xorg and gnome I get a full 1280 X 800 without any problems.
When I enable any (or all) of the following under frame-buffer devices I get a blank screen. I have tried linking them to the kernel permanently as well as trying to enable them as modules.

VGA 16-color graphics support (NEW)
Userspace VESA VGA graphics support (NEW)
Intel 830M/845G/852GM/855GM/865G/915G/945G/945GM/965G/965GM support (EXPERIMENTAL) (NEW)

My notebook probably boots since after a minute when I enter a my username and password and type reboot and press enter it does reboot. I realize that even the RAMFS will reboot my computer if I type reboot but the HDD activity LED makes it pretty clear that the notebook does boot.

Any help is appreciated.

PS. An lsmod on the Arch Linux kernel shows me something like intel_agp. I think that this might be missing the in kernels I have compiled. I will have to double check though.

You should be using kms now:

Re: [SOLVED] The 773 vga mode?

If u want 1280x800 in framebuffer mode add vga=865 to kernel line in menu.lst. Or use kms as my countryman moljac suggests...

A while back when I was on ubuntu, I've compiled 2.6.29-1 from source and couldn't get framebuffer resolution but on stock kernel it worked fine...
Haven't tried to add vesafb and fbcon to /etc/mkinitcpio.conf in the modules section... Could patched things up I think...

Woah, you shouldn't even be using vga=, that's for vesa. You should use intelfb. I'd recommend

Devices Drivers ---> Graphics support ---> Direct Rendering Manager (XFree86 4.1.0 and higher DRI support)
[Y] Intel 830M, 845G, 8252GM, 855M, 865G (i915 driver) ---> 
       i915 driver
[Y]       Enable modessetting on intel by default

Device Drivers ---> Graphics support ---> Console display driver support
[Y] Framebuffer Console support

In /boot/grub/menu.lst, you'll want on the kernel line

video=intelfb:1280x800-24@60

Don't use vga. That's for vesa.

@Aprz Thanks man; Now I get a very neat native 1280 x 800 resolution when I boot up.
