how can i change to a compatible pixel format? by editng xorg.conf?
I haven't used xorg but probably that conf file has the info on pixel depth.
yes, the default ubuntu xorg.conf is set to 16bit depth buffer.
i usually change it to 24 for better gem performances, but it usually work with
the default config.
you can try changing the DefaultDepth from 16 to 24 in your xorg.

what is 'glXIsDirect' ? where did you see that? which message in GEM ?
forgive me my slow understanding and thanks a lot for your help.
glXIsDirect checks that the GL can be drawn directly to the screen and
not be touched by the x11 server.
