Sorry to re-open but I wanted to include one more detail - either a recent update fixed this for me, or a recent change I made to my BIOS settings (changing my fan speed from "normal" to "turbo" in my motherboard BIOS) has made me unable to reproduce this hang, even after long periods of scrolling complex maps in Google Maps. I can definitely raise the temperature nearly 10C by doing this, but with the fans on turbo (and this only seems to make it slightly louder) the hang does not occur. Hopefully this will help anyone else with these issues - always try to cool the processor as much as possible!

I noticed that everytime I play something like Counter Strike Source, my graphics performance drops down to something like 15fps while normally it is locked at a max FPS of 40fps.. This slowdown happens and also makes my computer generally pretty slow. Thermo maximum has not been tripped (I know, and I actually underclock while playing these games). I'm not sure why this is happening. It only happens on 13.10. I have bumblebee installed. I used both cards to play the game and the same thing happens ProblemType: Bug DistroRelease: Ubuntu 13.10 Package: linux-image-3.11.0-11-generic 3.11.0-11.17 ProcVersionSignature: Ubuntu 3.11.0-11.17-generic 3.11.3 Uname: Linux 3.11.0-11-generic x86_64 ApportVersion: 2.12.5-0ubuntu1 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: shuhao 2611 F.... pulseaudio shuhao 4063 F.... plugin-containe /dev/snd/pcmC0D0p: shuhao 4063 F...m plugin-containe /dev/snd/timer: shuhao 4063 f.... plugin-containe Date: Mon Oct 7 20:39:17 2013 HibernationDevice: RESUME=UUID=0c4e9477-6a74-48cb-a0e4-37bc3251580e InstallationDate: Installed on 2013-07-08 (91 days ago) InstallationMedia: Xubuntu 13.04 "Raring Ringtail" - Release amd64 (20130423.1) MachineType: LENOVO 4180J4C MarkForUpload: True ProcFB: 0 inteldrmfb ProcKernelCmdLine: BOOT_IMAGE=/vmlinuz-3.11.0-11-generic root=/dev/mapper/xubuntu--vg-root ro quiet splash i915.modeset=1 i915.i915_enable_rc6=1 i915.i915_enable_fbc=1 i915.lvds_downclock=1 PulseList: Error: command ['pacmd', 'list'] failed with exit code 1: Failed to create secure directory (/run/user/1000/pulse): Permission denied No PulseAudio daemon running, or not running as session daemon.
