Error of Beryl+AIGLX on i965

[Wang, Wei Z]

Thank you Adrew for your kind help :)

As for the "(II) AIGLX: Loaded and initialized /opt/X11R7/lib/dri/i915_dri.so"
Sorry for the typo, it should be _i965_dri.so_ and I am sure I did it on i965 HW. Actually, this AIGLX warnings appear on several of our test machines (i945, i915 and i965), so I just copied and pasted from some i915 machine by mistake. But the warning (WW) is real and exactly as the warning on i965 machines:)


And pls. see [Wei] below. Thank you for your attention.

[Wei] Before GLX 1.3 is available, and workaround to enable compiz?
We just gave a quick try on FC6 with its compiz+AIGLX, however, everytime we push the "Enable desktop effects" button, it returns us the gnome login screen without any cube effects. -- maybe it is also the "GLX_ext_texture_from_pixmap" 's reason ?

[Wei] thanks :)

[Wei] Actually I really want to know the root cause of these warnings :)

[Wei] do you mean that warning "3D driver claims to not support visual 0x5a " doesn't matter? My white screen are all due to the missing of 
"GL_ARB_fragment_program"?

[Wei] thank you.
