Console frambuffer problem

I compiled a new kernel (2.6.11.6) but i can't get the console framebuffer to work.
i enabled Framebuffer support, Radeonfb, vesa_fb (module), vga text console, and video mode select (the "vga=" option). But all i get on boot is just a black screen. I know its just a simple problem, becuase my system works, i can wait till it finishes booting and start X, but i can't see anything in the console.

also, do i need to enable one of the fonts options in the console framebuffer menu?

any help is greatly apreciated.

i looked at the post and made sure i had all the options enabled, and i STILL can't get it working!
I notice that i could find 1 option: CONFIG_PCI_CONSOLE
i looked inside .config with pico and i could find it either so i just added it manually.

I also have two different FrameBuffer drivers enabled.... Is it possible that they conflict?

Vesa needs to be compiled in. (Module won't work ;))

the Vesa_fb IS compiled into the kernel.

i already tried removing the radeonFB driver but have had no success.i still see just a black screen.

im pretty sure its something i'm doing wrong, but i haven't found the problem.
i'll try to post my .config later.

thanks for the help/patience.

I still haven't found a solution to the problem, I really need help on this one.

i've tried to compile my kernel, after doing a make mrproper, over and over again. i cant figure it out

After correcting the values with the link I gave you here, did you actually recompiled and installed again the kernel?
If you did, post the relevant lines from your .config (Graphics support, Console display driver support and maybe some other).

As you've enabled CONFIG_FB_RADEON_I2C, is the relevant I2C stuff therefore also enabled?

Device Drivers --> I2C Support

Do you use lilo or grub? Maybe the problem is with one of those.

I use lilo installed in the master boot record and use 1024x768x256 mode. Here are the relevant lines in the global section:

Code:

        boot = "/dev/hda"

        # VESA framebuffer console @ 1024x768x256

        vga = "773"

Don't forget to rerun lilo after any changes!
