r700 karmic problem with kms

[Sly154]

Hi everyone,
i have some trouble with my radeon 4870 when using KMS. I'm using ubuntu karmic and radeon driver from the xorg edgers ppa. xserver, mesa and libdrm are also from xorg-edgers ppa. The problem is a black screen after the ubuntu logo during the boot.
I have looked the dmesg log and i think it's saying that kms is working. I can't have a look to the xorg log because i didn't have access to the console.
I am using kernel 2.6.32rc5 from ubuntu mainline.


dmesg log :

heh, same issue here, I'm using this workaround

boot with option - single

then choose root terminal in menu, and modprobe radeon modeset=1

if kms was activated succesfully (resolution was changed and no black screen), then type exit and choose resume in menu.

2.6.32-rc5 vanilla

Ok, thanks. Its working

It's also enough for me to just omit usplash, so removing the splash option from the kernel commandline works perfectly for me.

I have a problem integrating modules for radeon kms in the initrd. I've put all the reuqired modules in the initrd, but when I boot up the firmware loader fails to load the firmware. I've tried to put that piece in the initrd too but wherever I put it, it's not found. Did anyone suceed here ?

removing splash option didnt work for me.

Also, I edited initrd and added fw there, it was just freezing when drm was initialized.

just updated to karmic and it doesnt work there, damn upstart doesnt start X if i booted with single option, and doesnt let me to modprove radeon module if i comment "single" check in gdm.conf, it just starts gui

also tried to modprobe radeon modeset=1 in gdm.conf,

i can see kms activated, cuz res was changed, but when X start, all i have is lower half of screen with colored snow.

anyone knows where to submit kms bugs?

found a way for myself to launch kms rv770 in ubuntu 9.10
added DRI section to xorg.conf.

boot with single,
menu->root
modprobe radeon modeset=1
menu->resume
console login
sudo su
xinit -- /usr/bin/Xorg -ac -config /etc/X11/xorg.conf
run glxgears in xterm (maybe not needed)
terminate Xorg server (exit xterm for example)
remove single check in /etc/init/gdm.conf
sudo start gdm

automized it with script to run in fb console
kms works now, no other way to get it working, booting with radeon.modeset=1 - black screen after Xorg launch, adding modprobe radeon modeset=1 to gdm.conf - same result.

before rebooting repair "single" check in gdm.conf
