The issue occurs regardless whether the suspend state was activated by low battery, by closing the display, or by explicitly selecting sleep mode in KDE. Killing and restarting X does not solve the problem. A reboot does. --- ApportVersion: 2.14.1-0ubuntu3.5 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: michael 2554 F.... pulseaudio michael 2784 F.... pulseaudio CRDA: Error: [Errno 2] No such file or directory DistroRelease: Ubuntu 14.04 HibernationDevice: RESUME=UUID=8dc81a6f-65e9-443d-b850-0f62a1ca52c4 InstallationDate: Installed on 2012-05-13 (909 days ago) InstallationMedia: Kubuntu 12.04 LTS "Precise Pangolin" - Release amd64 (20120424) MachineType: Hewlett-Packard HP EliteBook 8530w Package: linux (not installed) PccardctlStatus: Socket 0: 3.3V 16-bit PC Card Subdevice 0 (function 0) bound to driver "pata_pcmcia" ProcEnviron: LANGUAGE=en_US:en TERM=xterm PATH=(custom, no user) LANG=en_US.UTF-8 SHELL=/bin/bash ProcFB: 0 nouveaufb ProcKernelCmdLine: BOOT_IMAGE=/vmlinuz-3.13.0-39-generic root=/dev/mapper/vg00-lv_root ro quiet splash vt.handoff=7 ProcVersionSignature: Ubuntu 3.13.0-39.66-generic 3.13.11.8 PulseList: Error: command ['pacmd', 'list'] failed with exit code 1: No PulseAudio daemon running, or not running as session daemon.
