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.
