libGL warning - ATI 3D driver not working properly

[scoonma]

Howdy folks,

 

even with actual ATI drivers and xorg-server this is not what it meant to be - at least compared to the proprietary drivers:

I did a

 

$ LIBGL_DEBUG=verbose glxinfo

 

to find out why; obviously the driver looks for a config file:

 

libGL error: 
Can't open configuration file /etc/drirc: No such file or directory.

 

Unfortunately, there's no such file available (no results on "urpmf /etc/drirc").

 

I don't want to fall back on the proprietary drivers, as they are still unable to do load composite extension with acceleration enabled. ;-)

 

Video card is ATI Radeon 9600 SE AQ (RV 350). There are also multiple warnings in Xorg.0.log containing warnings of the form "AIGLX: 3d driver claims not to support visual 0x.."

 

Any ideas please?

At least I've found out about the drirc error: The file is has no impact to the rendering engine itself (as I presumed), it's rathermore a configuration file targeted to per-application settings in xml format:

 

http://dri.freedesktop.org/wiki/ConfigurationInfrastructure

 

The caveats marked as slow by glxgears still persist with actual cooker files. OTOH, 3D desktop and googleearth run quite well yet.
