The same bug occurs for me using the linux-image-generic kernel version 3.5.0-26. I experience frequent apport error messages (I had to turn it off), degraded performance, and GPU hangs which necessitate a reboot. I am now using 3.5.0-23-generic, and the problem no longer occurs. I am using an Intel Core i7 with a 2nd Generation Core Processor Family Integrated Graphics Controller.
As a workaround, tell GRUB to boot an older kernel. You may need to hold SHIFT at startup to get the GRUB menu to appear. Select the "Advanced options for Ubuntu" in order to access your list of old kernels. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1157649 Title: GPU hang To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1157649/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
