apport information ** Tags added: apport-collected reproducible saucy ubuntu
** Description changed: 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. + 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.
