Currently I have both ATI HD 6470M and Intel i5(Intel Graphics HD 3000) on my laptop. Version of my kernel is 2.6.38(so the Intel Graphics chip is somewhat working). I did not install the close-source ATI graphic card driver.

Every time I try to play videos, X will just gone dead, but the audio part was always still working. I also tried to use xv and SDL as the video output, but they make no difference.

I tried running some simple SDL programs. It worked, but starts up extremely slow.

Here is some info that may help:
