Arch, Intel, Mesa 7.5, Software Rasterizer

поставил недавно арч, возникла проблема.
видеокарта intel x3100. mesa стоит 7.5.

все должно работать, но
$ glxinfo | grep render
direct rendering: Yes
OpenGL renderer string: Software Rasterizer

в Xorg.0.log ничто не говорит о нерабочести, хотя если нужно могу выложить. может я чего то не заметил.

в чем может быть проблема?
