  • Change Kernel in Ubuntu Lucid

    Hi,

    After installing lucid alpha 2 and enable xorg-edgers, radeon OSS is working great! i have kms and dri2 and i am runing some opengl test now. WOW!! great progress.

    But what i cant understand is that if i change the kernel from 2.6.32.10 (lucid a2 default) to 2.6.33.rc4 my screen turns black, ubuntu doesn't boot.

    I tried 3 workarounds without success:

    1) Edit /etc/initramfs-tools/modules and add radeon. Run update-initramfs -k all -u

    2) Add R600_rlc.bin and R700_rlc.bin to /lib/firmware/radeon/ and to /lib/firmware/2.6.33-020633rc4-generic/radeon/

    3) Edit /etc/modprobe.d/radeon.conf and add options radeon modeset=1

    any ideas?

    Is there any useful info in the dmesg or xorg.log output ?

      and its hart to post the xorg.log or dmesg here because only a init3 bash work...

      if you give some help/instruction i can post this here.
      dmesg > file.txt

      And similarly for xorg.log. Then open the file with your working config and paste it where you like.

        Code:
        [   49.093468] [drm] radeon defaulting to userspace modesetting.
        Your kernel isn't using KMS. The 33rc4 isn't reacting on radeon.modeset=1 on my setup. I created this diff which have to be applied on top of /usr/share/initramfs-tools/scripts/init-top/framebuffer:
        Code:

                esac
         done
        And then initrd must be updated.
