log out is 800% slower than usual (pre 13.10), now around 10 sec. On nvidia hardware, 8400m gs, doesn't matter if nouveau or nvidia, (currently 3.10 kernel, 319 drivers), current, newer or older kernels inc. raring's, lightdm or gdm, ect., 10 secs on/with all combos.
Didn't happen early on in 13.10 but has existed for some time now, whatever you all where doing with systemd, upstart *may * have been around when first seen -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-video-nouveau in Ubuntu. https://bugs.launchpad.net/bugs/1191426 Title: logout is slow, profiling reveals lots of CPU time in nouveau_connector_detect Status in “linux” package in Ubuntu: Triaged Status in “xserver-xorg-video-nouveau” package in Ubuntu: Confirmed Bug description: I'm running Ubuntu 13.10 (Saucy) on a MacbookPro9,1, which has both an Nvidia GeForce GT 650M and an integrated Intel HD Graphics 4000 controller. 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.
