Both /var/log/messages and /var/log/syslog doesn't show anything of interest. If I knew how, I could raise the detail level to debug. I don't remember how to do that, though...
Anyhow, in the attachement you find logs from both syslog and messages. The steps taken are: 08:41 log out (from gnome panel) ...system freezes with only wallpaper and mouse button shown... 08:56 quick press on the power button ...normal shutdown... 08:59 start the machine again ** Attachment added: "syslog output" http://librarian.launchpad.net/5234970/messages -- Can't log out from gnome session in Edgy https://launchpad.net/bugs/71544 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
