Radeon Gallium on ubuntu

[Gerwin]

Is it possible to have 4x agp with the r300g?

The only way I can set the agp at 4 times is using radeon.modeset=4 in the grub config file, but then I get an error:

do_ioctls: DRM version is 1.32.0 but this driver is only compatible with 2.x.x

Looks like radeon.modeset=4 means no KMS for you and it's a prerequisite for the driver to work.

Is it possible to have KMS and 4x agp? With the r300 driver running at 4x agp, my frame rates are at least two times higher (octaga vrml player, blender, glxgears) and artifacts are gone...

Note that it should be radeon.agpmode=4 and the modeset parameter on the other hand is either 0 (off) or 1 (on, default). Type "modinfo radeon" when in doubt.

Good catch. I saw an earlier reference to radeon.modeset=4 and was wondering what option 4 would do

As of today My AGP x1600pro (512MB) is still having issues

I booted with no argument at all or radeon.agpmode=4 or radeon.agpmode=8 and the results are the same.

The thing is Saturday was working..

$ glxinfo | egrep Gallium

My AGP card is being recognized as a PCIe.

No compiz love for me.

Any ideas?

What did you change between Saturday and whenever it stopped working ?

I did a couple of updates from xorg-edgers ppa. And yesterday I installed Wine.. but i never even executed it.

When I booted today I noticed that compiz was gone.. and here I am

I tried to use latest PPA date 04302010 for the gallium, the screen gets corrupted whenever I open a menu. I had to revert to classic mesa driver to get to stable. I tried with latest Kernel .34rc6 and ubuntu official kernel.

[marek]

There is a regression in higher levels of Mesa, all gallium drivers are affected by this, people are working on a fix.
