Public bug reported: Hi,
I have noticed this issue after a wakeup from a hibernate usually. Today I had been using the laptop after a successful wake and then I updated the kernel today using apt-get updated. I went to the console window using Ctrl+Alt+F1 and on trying to return to the GUI window using Ctrl+Alt+F7 I saw this issue. I have gathered the information using ubuntu-bug linux after the reboot. Hope this suffices. BTW on launch pad it no longer allows me to specify the package as linux-kernel though the search shows it. Thought I did bring it to your notice. Thanks, Mayank ProblemType: Bug DistroRelease: Ubuntu 12.10 Package: linux-image-3.5.0-21-generic 3.5.0-21.32 ProcVersionSignature: Ubuntu 3.5.0-21.32-generic 3.5.7.1 Uname: Linux 3.5.0-21-generic x86_64 ApportVersion: 2.6.1-0ubuntu9 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: mayankr 2439 F.... pulseaudio /dev/snd/pcmC0D0c: mayankr 2439 F...m pulseaudio /dev/snd/pcmC0D0p: mayankr 2439 F...m pulseaudio Date: Wed Dec 19 18:43:44 2012 HibernationDevice: RESUME=UUID=564591e5-57fe-461a-8a09-2c31fdbbf2ee MachineType: LENOVO 2768GZ9 MarkForUpload: True PccardctlIdent: Socket 0: no product info available PccardctlStatus: Socket 0: no card ProcFB: 0 radeondrmfb ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-3.5.0-21-generic root=UUID=420a15eb-4d65-4f15-9c15-1ccc3dee8556 ro quiet splash PulseList: Error: command ['pacmd', 'list'] failed with exit code 1: No PulseAudio daemon running, or not running as session daemon.
