codice:
compiz: GLX_EXT_texture_from_pixmap is missing
compiz: Failed to manage screen: 0
compiz: No manageable screens found on display :0.0
e lì muore

eppure
codice:
[fredp@kurtz ~] $ glxinfo | grep texture_from_pixmap
libGL warning: 3D driver claims to not support visual 0x4b
    GLX_EXT_import_context, GLX_EXT_texture_from_pixmap, GLX_OML_swap_method,
    GLX_SGIX_visual_select_group, GLX_EXT_texture_from_pixmap


che può essere?
