Can you please be more descriptive than "stopped working"? Do you mean it booted to a black screen?

Are you certain it wasn't the linux update that brought the freeze? ** 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/717805 Title: [i855] GPU lockup 63f44359 (IPEHR: 0x02000011) -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
