Now I change the VIDEO_CARDS to "intel i965" Everything seems OK too. Gnome can detect Intel® Sandybridge Mobile rather than Gallium 0.4 for i915 I dont know the difference between classic and gallium but i965's classic mode works well. By the way, I think i965 is just for HD3000, why does i915 be suggested ?
