[Nouveau] Fedora and direct rendering

[Ioannis Nousias]

ok, I found the problem. 'ldd /usr/bin/glxinfo' revealed that it was 
linking to nvidia's libGL.so that's installed on my system. I changed 
the suffix of '/etc/ld.so.conf.d/nvidia-96xx.conf' , run 'ldconfig' and 
success !

well sort of ;) It now reports 'direct rendering: Yes', but the general 
feeling is that there is no acceleration. Moving windows or scrolling is 
slow. But it does as advertised. If I run glxgears it crashes the X 
server :-D

no wonder why Fedora chose not to include the nouveau_dri.so on their repos.

thanks guys. By they way, what happened to the nouveau crash course (no 
pan intended ;)) ?
