When use xf86-video-intel-2.9.1, it is OK to launch qtdemo. The attached file is the kernel message when X window freeze.
Created attachment 32468 [details] Kernel message when error happened.
Can't really say anything intelligent here without kernel version details. So I'll mark this bug as NEEDINFO until that data arrives, but will also re-assign to Eric. -Carl
