Public bug reported: the xfce desktop session starts multiple instances of xfce4-power- manager and xfce4-volumed, rendering power management ineffective and audio volume buttons dead. additionally, the lid switch causes hibernation irrespective of power management settings.
workaround: - edit /etc/xdg/autostart/xfce4-power-manager.desktop and change the corresponding line to Exec=xfce4-power-manager --no-daemon & - edit /etc/systemd/logind.conf and make sure to have this line enabled in the [Login] section HandleLidSwitch=ignore - disable automatic session saving in Settings | Settings Manager | Session and Startup | General - logout from your xfce desktop - login again - run "ps awxu | grep xfce" and kill (-9) all instances of xfce4-power-manager and xfce4-volumed - logout (might take a while for the connection to nonexisting power manager to timeout) - login again. run the "ps" command above again and check that there are no multiple instances of the two processes. if there are, repeat the kill procedure again, logout and run "ps" again - at this point starting of multiple instances stops (is there a bug in session saving?) and you should have properly working power management and volume buttons -note that updates of certain packages might reemergence of the symptoms, just repeat the procedure again ProblemType: Bug DistroRelease: Ubuntu 13.10 Package: xfce4-session 4.10.1-1ubuntu1 ProcVersionSignature: Ubuntu 3.11.0-13.20-generic 3.11.6 Uname: Linux 3.11.0-13-generic x86_64 NonfreeKernelModules: wl ApportVersion: 2.12.5-0ubuntu2.1 Architecture: amd64 Date: Mon Nov 25 22:16:59 2013 InstallationDate: Installed on 2013-11-07 (17 days ago) InstallationMedia: Ubuntu 13.10 "Saucy Salamander" - Release amd64 (20131016.1) MarkForUpload: True SourcePackage: xfce4-session UpgradeStatus: No upgrade log present (probably fresh install) ** Affects: xfce4-session (Ubuntu) Importance: Undecided Status: New ** Tags: amd64 apport-bug saucy -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1254881 Title: xfce session starts multiple instances of xfce4-power-manager and xfce4-volumed To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xfce4-session/+bug/1254881/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
