[je_sse]

i run ubuntu 9.04 on my laptop lenovo x61.the graphics chip is intel x3100.but when i open an iso it just shows a black screen.
somtimes shows many alsa underrun, is it crashed?
sometimes just stops when it shows detect direct plugin.
so strange
and the new mesa 7.4 support opengl 2.0 on x3100 so i wanna know whether now it can support the ogl plugin.
