At least here on previously affected machine this is longer an issue, log outs are back to about 1 sec. or so

I boot with EFI and use the Nouveau driver. On this machine logging out is slow, taking maybe 10 seconds or so. 'top' shows that the X server process uses lots of CPU during logout. I ran sysprof and it attributes much of the CPU time to nouveau_connector_detect, called via the following: system_call_fastpath [48.98%] sys_ioctl [41.90%] do_vfs_ioctl [41.87%] drm_ioctl [41.47%] drm_mode_getconnector [34.14%] drm_helper_probe_single_connector_modes [34.14%] nouveau_connector_detect [28.84%] nouveau_connector_detect_lvds [3.83%] intel_crt_detect [1.48%] The percentages above are of the total CPU time used in the shutdown sequence, so I think several seconds of time is being spent in the path above. That doesn't seem right. --- ApportVersion: 2.10.2-0ubuntu1 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC1: adam 1744 F.... pulseaudio /dev/snd/controlC0: adam 1744 F.... pulseaudio CompizPlugins: No value set for `/apps/compiz-1/general/screen0/options/active_plugins' DistUpgraded: Fresh install DistroCodename: saucy DistroRelease: Ubuntu 13.10 DistroVariant: ubuntu DkmsStatus: bcmwl, 6.30.223.30+bdcom, 3.9.0-4-generic, x86_64: installed bcmwl, 6.30.223.30+bdcom, 3.9.0-5-generic, x86_64: installed bcmwl, 6.30.223.30+bdcom, 3.9.0-6-generic, x86_64: installed ExtraDebuggingInterest: Yes, including running git bisection searches GraphicsCard: Intel Corporation 3rd Gen Core processor Graphics Controller [8086:0166] (rev 09) (prog-if 00 [VGA controller]) Subsystem: Apple Inc.
