From the horses mouth: TLP is a power management tool for Linux. It brings you the benefits of advanced power management without the need to understand every technical detail.

To clarify, you experience the issue with kernels as far back as 3.4.50? If you can install a 3.2 that would be good to check. Indeed that it does not present itself in any logs or as an obvious effect, is very worrying.

The NMI error is a bug in that kernel's perf (iirc). I still haven't seen anything to suggest a reason for any slowdown. Must be as infuriating for you as it is for me. Can you please watch top and sudo perf top whilst the system is idle and lightly loaded to learn the expected behaviour, then inspect the system during the slowdown to see what stands out?

[Bug 1189645] Re: General lag under desktop environments
So far I think we've established that it is not a rouge CPU hog that is blocking the system. Having to restart the system rather the session, also lends credence to that it is not a simple userspace or even gfx driver issue. On the theory that the GPU goes nuts, download and build http://cgit.freedesktop.org/xorg/app/intel-gpu-tools/ (maybe apt-get install intel-gpu-tools if you feel lucky), then run intel_gpu_top. Except for running gtkperf etc, the GPU should be lightly loaded. On the theory that the CPU goes nuts, apt-get install powertop latencytop, and run the pair of those looking for abnormalities. For powertop, the CPU should be waking up and hitting max frequency when busy and hitting C6+ when idle. latencytop should help identify what is taking time (not necessarily cpu cycles) to complete. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1189645 Title: General lag under desktop environments To manage notifications about this bug go to: https://bugs.launchpad.net/xserver-xorg-video-intel/+bug/1189645/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Looks like a UXA versus SNA problem. https://wiki.ubuntu.com/X/Testing/IntelSNA ~$ grep SNA init /var/log/Xorg.0.log [47.176] (II) intel(0): SNA initialized with gen3 backend The default is SNA, which is fast, until something goes wrong, then it gets really slow. If I start with UXA, it is slow from the beginning. I assume that under 12.10, intel graphics was using UXA, and performance was reasonable. Under 13.04, UXA is unusable.

So this issue does happen with the 3.8.13 kernel eventually, as well as the 3.9 and 3.10 kernels?

[Bug 1189645] Re: General lag under desktop environments
The flashplugin was recently updated and I can't reproduce the issue. Where can i get the previous version of Flash? Regardless, a buggy flash plugin should not, I think, affect the whole system. When the issue occured, a complete shutdown was needed to restore sanity. A simple restart did not help. Once I can load a older flash plugin I can continue to test different kernels. For all I know, older kernels also have the issue, but were not triggered by the flash plugin at that time. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1189645 Title: General lag under desktop environments To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1189645/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Would it be possible for you to test the latest upstream stable kernel? Please test the latest v3.8 stable kernel[0].

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
