I notice that the git changeset which is said to cause the regression (in that report), adds a check and message "Non-contiguous GTT entries". Interestingly, the package from Bryce (which fixes the screen but breaks 3d) for me results in this message in my Xorg.0.log. Specifically, I get an error message: (EE) intel(0): Non-contiguous GTT entries: (6295552,0x163ffbe000) vs (131072,0x 3f820000) (WW) intel(0): xf86AllocateGARTMemory: allocation of 1536 pages failed (Cannot allocate memory) This doesn't appear in my Xorg.0.log with the stock Gutsy driver. -- screen artifacts after resume, part row of pixels in error (945GM) https://bugs.launchpad.net/bugs/91966 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
