Some months now, it's taking very long to logout/shutdown/reboot my ubuntu box. it doesn't happen with a fresh profile it still takes ages even when i close all running programs first (foreground programs) sometimes a couple of applications are closed before the waiting time (eg. chrome, music player) it happened with 11.10 and now 12.04 i did a fresh install of 12.04 but reinstalled all my programs and application settings/profiles (eg. chrome profile, music db, .bashrc etc.), still no solution it happens only when i use the gnome way of rebooting/shutting down/logging out when issuing "sudo reboot" in the terminal, there is no waiting time there is no process eating CPU time i have not found any evidence what is causing this whatsoever i'm using "gnome-fallback" (gnome classic 2D) what actions does gnome execute when clicking on eg. logout exactly? i want to trace these steps any help is appreciated very much!
