Algo estranho ao iniciar a sessao XGL

[fabianoheringer]

Oi Pessoal...

Seguinte, tenho uma ATI RADEON X800XT-PE funcionando perfeitamente no Ubunutu, Direct Rendering e tudo mais...
Meu problema é: ao iniciar uma Sessao XGL para iniciar o BERYL, é ai que o Direct Rendering nao funciona...

Abaixo meu log do Xorg da parte onde fala sobre DRI

Se perceber nota que o DRI foi inicializado com sucesso, nao houve nenhum erro referente a Direct Rendering...
mas quando rodo glxinfo:

fabianoheringer@fabianoheringer:/var/log$ glxinfo
name of display: :1.0
Xlib:  extension "XFree86-DRI" missing on display ":1.0".
display: :1  screen: 0
direct rendering: No
server glx vendor string: SGI
server glx version string: 1.2

O mais interessante que o beryl ta rodando beleza, rapido e tudo mais...

Dei uma lida num site ele falou que o XGL nao habilita o Direct Rendering, mas utiliza um tal de pbuffer das placas de videos, o que equivale ao Direct Rendering...isso procede? Se alguem souber de algo a respeito e puder compartilhar...

Muito Obrigado!!!
