$ compiz --replace
compiz (core) - Fatal: GLX_EXT_texture_from_pixmap is missing
compiz (core) - Error: Failed to manage screen: 0
compiz (core) - Fatal: No manageable screens found on display :0.0

$ glxinfo | grep GLX_EXT_texture_from_pixmap
    GLX_ARB_multisample, GLX_EXT_import_context, GLX_EXT_texture_from_pixmap, 
    GLX_SGIX_visual_select_group, GLX_EXT_texture_from_pixmap

Looks like Gutsy's compiz refuses to play with my Intel X3100 (GM965), with or 
without XV... Some weeks ago I've tried to update both the Intel driver, Mesa and
DRM to the (then) latest git version but nothing changed.
glxinfo reports that direct rendering is enabled and 3D applications work. The server
log shows that AIGLX is enabled. I'm on x86_64, if that matters.

But I've seen people report that this configuration works after the SKIP_CHECK trick.
Any idea of what I'm doing wrong / where should I chase the bug? Not that I need
compiz that much, but I miss it a bit since it used to work on my trusty old R200 :)
