linux kernel 2.6.20, Radeon X600, no screen on console


Hi all,
I have some problems when upgrading my kernel from 2.6.18 to 2.6.20.

I have both kernel config for

CONFIG_FB_VGA16=m
CONFIG_FB_VESA=y

CONFIG_FB_RADEON=y
CONFIG_FB_I2C=y
CONFIG_DRM_RADEON=y

Kerel 2.6.18 works perfectly

The problem is that, when booting with kernel 2.6.20, the console does not have any display. I am running Slackware 11.0, boot level 3 by default. After lilo load the kernel, the screen is all black, but the system is running good. I can ssh in using an external system and rebuilt the kernel. When I try to startx, or try boot level 4, the screen display real nice. I think there is some problem with the framebuffer console driver, or something similar but dont know exactly what happened.

Sorry I cant post the whole .config content, there is a 25k char limit

thanks for reading
zeus

I just fixed this same problem with the same kernel upgrade

edit your lilo.conf and change the line to read

vga = normal


I put that line under the section for my 2.6.20 kernel so that it only disables it for that kernel. (because the vga framebuffer thing works fine with my 2.6.28 kernel)

Part about this that sucks is taht the screen resolution in my 2.6.20 kernel is much smaller now with that setting. (though at least the screen isn't black)
I'm still kind of new at this so if anyone can share how to get 1024 by 768 resolution and still see the screen id be most happy.

hi!

I have quite a similar problem, but just wanted to ask before I do anything.
i just upgraded from kernel 2.4.33.3 to 2.6.20.1 and I'm running slackware 11. When i start the computer every thing is ok except for the console which doesn't have a screen, so it's all black.

i figured it must something like above (either/or)

/boot/config:
CONFIG_FB_VGA16=m
CONFIG_FB_VESA=y

CONFIG_FB_NVIDIA=m
CONFIG_FB_NVIDIA_I2C=y

so i just take one away??
