Tiling is not being enabled properly. In your xorg.log there is: (EE) intel(0): Failed to set tiling on front buffer: rejected by kernel (EE) intel(0): Failed to set tiling on back buffer: rejected by kernel (EE) intel(0): Failed to set tiling on depth buffer: rejected by kernel
I think there has been some fixes for tiling upstream but I don't remember the details. I'd suggest that you try out mainline kernel 2.6.30-rc4 or later and see if that fixes your issue: https://wiki.ubuntu.com/KernelMainlineBuilds Anyway, intel has some known perf issues right now in jaunty. The primary bug tracking this situation is bug 252094, you'll likely see people mentioning a lot of different issues there but tiling is one of them. https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video- intel/+bug/252094 -- Slow/no 3d acceleration on Intel cards after upgrade to 9.04 https://bugs.launchpad.net/bugs/371662 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
