Actually, I see that xorg-edgers has even newer than Q4 bits, along with our new X stack.
Can you please reproduce your issue with this new stack? The PPA is available at: https://launchpad.net/~xorg-edgers/+archive/ppa Here's a simple way to install: sudo add-apt-repository ppa:xorg-edgers/ppa sudo apt-get update sudo apt-get upgrade Then reboot your system to get to the new bits. If you want to go back to stock Ubuntu, there is a corresponding ppa-purge tool: sudo ppa-purge xorg-edgers sudo apt-get update sudo apt-get upgrade ** Changed in: xserver-xorg-video-intel (Ubuntu) Status: Incomplete => New ** Changed in: xserver-xorg-video-intel (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/700282 Title: [i945gm] GPU lockup 585b0b66 (PGTBL_ER: 0x00000102) -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
