I continued using my desktop PC with intel G45 graphics, kernel 2.6.34.2 and intel driver with pageflipping enabled and no hangs occurred. Everything seems to work fine. I also compiled the intel 2D driver with pageflipping enabled on a notebook with intel GM965 graphics. I noticed an annoying issue: every few minutes (part of) the screen went black for an istant, maybe during a refresh. Then, I installed kernel 2.6.35 and this issue seems to be gone. I hope more people could test it, but I believe it is safe to enable pageflipping in the intel xorg driver with kernel 2.6.35. cheers, Stefano
