Change Kernel in Ubuntu Lucid

[Jimbo]

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 ?

i test this on my r300 test system to yesterday.

2.6.33 do not end in an blackscreen only you can also press key ctrg-alt-f2

then you have a init3? console!,,,

yes on my system to 2.6.33 fails to start X on this setting.

to blacklist your kernel for the next boot
just edit your
vi /boot/grub/grub.cfg

put some '#' in the 2.6.33 session..

I can confirm the bug.

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.

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:

And then initrd must be updated.
