Problems running Radeon Framebuffer (radeonfb)

Postby Vultaire » 2007-07-19 05:11


I am having issues getting the radeon framebuffer to work on Debian sid. I am using a 2.6.21-5 kernel which is configured using the debian "stock" 2.6.21-2-k7 kernel's config except that I took out the paravirt option. The kernel was compiled "the Debian way" (make-kpkg --initrd kernel_image).

The modules for ATI are being compiled:
Code: Select all
> ls /lib/modules/2.6.21-5-k7-nopara-2/kernel/drivers/video/aty
aty128fb.ko  atyfb.ko  radeonfb.ko

I have added an appropriate boot option to my /boot/grub/menu.lst:
Code: Select all
title      Debian GNU/Linux, kernel 2.6.21-5-k7-nopara-2 (RADEONFB)
root      (hd0,0)
kernel      /vmlinuz-2.6.21-5-k7-nopara-2 root=/dev/sda5 ro video=radeonfb:640x480-32@60
initrd      /initrd.img-2.6.21-5-k7-nopara-2

...No good. Beyond that, if I boot without the video option above and try to modprobe the radeon driver:
Code: Select all
>modprobe radeonfb mode-option=640x480-32@60
>lsmod | grep radeonfb
radeonfb               97472  0
fb_ddc                  2880  1 radeonfb
i2c_algo_bit            7624  1 radeonfb
i2c_core               20928  4 radeonfb,fb_ddc,i2c_algo_bit,i2c_piix4
>cat /proc/fb
(totally blank)
>dmesg | grep radeon
(also totally blank)

The module gets loaded, it seems to take the mode-option, but then nothing happens.

Can anyone point me in the right direction here? Thanks.

By the way, video card is a Radeon Xpress 1100, which lspci returns as a "01:05.0 VGA compatible controller: ATI Technologies Inc RS482 [Radeon Xpress 200M]".
