Ahhh, cool, glad you got it working. I wasn't aware of that patch :-)

actually, I didn't got it to work. =(
I just recompiled 2.6.33 kernel with CONFIG_PREEMPT_NONE=y and am doing pre-reboot routines. Will let you know whether I got it working or not.

yup, not working.

despite not having 3D acceleration either, radeonhd driver "feels" much better than radeon.

i'll probably have to perform a clean install on my desktop soon enough and hopefully by then this issue will be solved.

3D is functional for all r100 through r700 radeon GPUs (up-to and including the HD4950) with the latest Mesa and libdrm code if you are using 2.6.33. I do not know what -current is using, though, so it's possible that it's not recent enough. Can you let me know what version of mesa and libdrm you currently have installed?

Code:
gtl@cpc-5564:~$ ls /var/log/packages/mesa*
/var/log/packages/mesa-7.7-x86_64-1
/var/log/packages/mesa-compat32-7.0.3-x86_64-1_slamd64
gtl@cpc-5564:~$ ls /var/log/packages/libdrm*
/var/log/packages/libdrm-2.4.18-x86_64-1
/var/log/packages/libdrm-compat32-2.3.0-x86_64-1_slamd64
gtl@cpc-5564:~$

Well those versions should be new enough... At least the x86_64 versions are. The compat32 packages are too old, so you won't be able to get 3D acceleration with 32-bit apps.

If you're interested in pursuing this further, please pastebin your /var/log/Xorg.0.log file.

I realize compat32 packages are old, even though I rsync 'em quite often, I miss installing the updates.

You have the catalyst drivers still installed, at least partially. Check where Xorg loads libglx and you'll see references to FireGL. You need to completely remove catalyst to get 3D acceleration working with the open source drivers.

paproch at Phoronix Forum replied with instructions how to patch the driver. It goes something like this:
Code:
~$ mkdir ati
~$ sh ./ati-driver-installer-10-2-x86.x86_64.run --extract ati/
~$ cd unpacked_ati_directory
~$ patch -p1 < ../fglrx.2.6.33.patch
~$ su -c 'sh ati-installer.sh . --install'
it gets patched and installs ok, I couldn't get X to start, though. Not sure if it's this driver-related or not.

can someone confirm whether this works or not?

As I said - I tried it ... and it did not work ... I'm downgrading back to 2.6.32.7

adamk75,
AFAIK I managed to remove all Catalyst debris. Here is the pastebin of /var/log/Xorg.0.log

i think the solution is not with changing the CONFIG_PREEMPT options but rebuilding the drm/agp/radeon modules from the 2.6.33 source. kms is working fine with the 2.6.32 kernel with CONFIG_PREEMPT_VOLUNTARY=y on my machine

i've posted some information regarding my problems after updating to current here http://www.linuxquestions.org/questi...59#post3884359. might be of some relevance

Unfortunately, the catalyst drivers overwrote parts of Xorg:

Code:
(WW) Warning, couldn't open module dri
(II) UnloadModule: "dri"
(EE) Failed to load module "dri" (module does not exist, 0)
That module is provided by xorg-server package which you will want to reinstall.

adamk75,

I reinstalled Xorg and posted /var/log/Xorg.0.log here.

After
Code:
$ export LIBGL_DEBUG=verbose
Either with "radeon" or "radeonhd", I get this output from glxinfo.
