intelfb - setting resolution

Hi,

I want my framebuffer to match my laptops resolution of 1440x900.
I have a intel onboard video card, so I figured, I should use the intelfb module.

So I added: video=intelfb:1440x900-24@60
To my grub kernel line.
I do not get any difference to before.
Looking through my dmesg outout, these lines seem relevant:

agpgart: Detected an Intel 965GM Chipset.
agpgart: Detected 7676K stolen memory.
agpgart: AGP aperture is 256M @ 0xe0000000
intelfb: Framebuffer driver for Intel(R) 830M/845G/852GM/855GM/865G/915G/915GM/945G/945GM/965G/965GM chipsets
intelfb: Version 0.9.5
ACPI: PCI Interrupt 0000:00:02.0[A] -> GSI 16 (level, low) -> IRQ 16
intelfb: 00:02.0: Intel(R) 965GM, aperture size 256MB, stolen memory 7932kB
intelfb: Non-CRT device is enabled ( LVDS port ).  Disabling mode switching.
intelfb: Video mode must be programmed at boot time.

So how do I program my video mode at boot time?

Thanks!

Re: intelfb - setting resolution

I just came across this in the 'arch discussion'-section: http://en.wikipedia.org/wiki/VBE#Linux_ … de_numbers

I think you just need to pass the vga=XXX parameter at the kernel-line in grub, where XXX is the number of the resolution you would like to see (between 864 en 868, depending on the amount of colours you would like to see)

Zl.
