The hardware is a Lenovo x121e. Ditch ModemManager "solves" the problem. But I would say it is not a proper solution.

My laptop does not shut down properly anymore. It used to take only 5 sec to shutdown in 14.04. But now it needs ca. 5 min to shut down after sleep. If it never slept, then shut down process is normal. The message on the shut down screen has something to do with ModemManager: ModemManager: ModemManager is shut down ModemManager: Could not acquire the 'org.freedesktop.ModemManager1' service name it stays like that for ca. 5 min before it suddenly shuts down. I added stop on runlevel [06] to the network-manager.conf file. It did not help. I used shutdown -h now. It did not help. modemmanager: Installed: 1.2.0-1 Candidate: 1.2.0-1 Version table: *** 1.2.0-1 0 500 http://archive.ubuntu.com/ubuntu/ utopic/main amd64 Packages 100 /var/lib/dpkg/status ProblemType: Bug DistroRelease: Ubuntu 14.10 Package: modemmanager 1.2.0-1 ProcVersionSignature: Ubuntu 3.16.0-24.32-generic 3.16.4 Uname: Linux 3.16.0-24-generic x86_64 NonfreeKernelModules: fglrx ApportVersion: 2.14.7-0ubuntu8 Architecture: amd64 CurrentDesktop: KDE Date: Tue Nov 18 15:10:26 2014 InstallationDate: Installed on 2012-03-22 (970 days ago) InstallationMedia: Ubuntu 11.10 "Oneiric Ocelot" - Release amd64 (20111012) SourcePackage: modemmanager UpgradeStatus: Upgraded to utopic on 2014-10-24 (25 days ago) mtime.conffile..etc.init.modemmanager.conf: 2014-11-18T10:37:43.218538 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/modemmanager/+bug/1393800/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
