Radeon Gallium on ubuntu

[tovj]

Hi, I am new to the forum and was wondering whether anyone could offer any advice on problem that I am having testing the r300g driver on my 9600XT AGP card with Ubuntu 10.04.

I installed Gallium3D using the xorg-edgers PPA (https://launchpad.net/~xorg-edgers/+archive/radeon) and initially everything looked great.

The results from "glxinfo | grep OpenGL" are:

OpenGL vendor string: X.Org R300 Project
OpenGL renderer string: Gallium 0.4 on RV350
OpenGL version string: 2.1 Mesa 7.9-devel
OpenGL shading language version string: 1.20

... so that seems good. Compiz works great, glxgears runs at about 1400FPS and Neverball runs nicely - it looks on a par with the old r300 driver.

Hovever, as soon as I try to run Google Earth it grinds to a halt - I reckon about one frame per second at best. With OpenArena I get similar results; I am getting less than one FPS at 800x600, as opposed to about 44 FPS using the old r300 driver!

So I'm guessing that something is either wrong with my setup, or the driver doesn't like something about my card. Does anyone have any ideas? As far as I know I havn't modified anything since performing a clean install Lucid.

Thanks

I understand all your perplexities tormod, sorry if i miss your time .

Probably I have problem with KMS and I don't know it... because I believed ATI driver doesn't support KMS (because ATI driver always has problem ) .
When I have more time I'll try to reinstall Lucid. But I'm not hopeful: when I've installed Lucid other times I've always disabled KMS: if I didn't disable, compiz didn't work.

Any suggest?

(Again sorry if i've mess your time, guys!)

You should also try a Lucid or Maverick live CD (will default to KMS) to see if everything is ok. That the 2.6.34 kernel makes your keyboard not work sounds strange, and I wonder if your system is a bit messed up. Anyway, I would go for 2.6.35-rc4.

[tormod]

Duma, if the normal "classic" mesa drivers do not work well with KMS, you probably have a KMS problem that you should solve before coming back here. Installing gallium drivers will not magically fix your system.

If there is a compiz effect that doesn't work with the Gallium driver, I'd like to know about that.

Both Alpha Blur and Focus Blur work there.

Sorry guys,
new kernel (2.6.34-02063401) is worse than 2.6.32 kernel.
It doesn't find my keyboard and if I try to run compiz or compiz++0.9 I see only my wallpaper with no icon, no panel, nothing .

Should I have to reinstall Lucid, update to 2.6.32 kernel and reinstall Gallium driver?

Gallium driver works with "default" compiz 0.8 better than normal radeon? I mean... I know they are experimental, but can Gallium driver support some "heavy" plugin like burn, alpha blur (very interesting about this), or similar?

normal radeon driver only support perfectly burn, with KMS disable, of course (I have a ATI Radeon X1600). Not Alpha Blur .

No
With out fglrx you can use a more recent kernel. I use 2.6.35.rc4 here

http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.35-rc4-maverick/

or if you prefer stable mainline

http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.34.1-maverick/

Ubuntu supples compiled images. It says maverick but Lucid is default KMS also.

Thanks a lot Sharky.
I remove this settings and now this is my situation:
if I try to able compiz (with compiz --replace or with System -> Preferences menu), compiz doesn't work good (slow). Looks like when I try to use normal "default" Radeon + KMS + compiz.
If I try compiz++ 0.9 works with a lots of bug: sometimes doesn't load Window decorator, sometime crash, etc etc.

Now I try with this new kernel, I post you the news.
Thanks a lot to all, guys!

Ops... How can i able KMS?

As nanonyme replied

Remove nomodeset switch from kernel line, remove uvesafb from kernel line, use KMS?

Then

sudo update-grub

make sure modules are registered

sudo update-initramfs -u

restart

Should I have to recompilate my kernel?

gallium on radeon depends on KMS, so make sure you have KMS (kernel modesetting) enabled and working if you want to try out gallium.
