There are a number of fixes about pageflipping with drm/i915 in the changelog of 2.6.34.2. So, I installed this new kernel and rebuilt xf86-video-intel without the patch to disable pageflipping. I have a G45 graphics and I suffered from frequent hangs with previous kernel versions and a 2D driver with pageflipping enabled. Now, using 2.6.34.2 and pageflipping enabled, I had my desktop running for 6 hours and no hangs occurred so far. I'll keep it running and report back if an hang occurs.
Thank you for this, please keep reporting it. We actually don't want to have page flipping disabled indefinitely.
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
