    Permissions?: Cannot shutdown, access webcam, etc.

    Hello, all.

    I don't know what triggers this, but every now and then I seem to lose the ability to do a lot of stuff:
    *access the webcam
    *shutdown from GNOME
    *change power manager preferences
    *mount external drives

    A reboot makes it all work again.
    This is on Fedora 14.

    Anyone else experienced something like this?

    Thank you!

    I have the same issue here! Fedora 14. I can't shutdown change power settings, usb disks. Also I can't use gnome's reboot if that happens. Robooting through command will work.

    This may happen after the suspension to ram.

    I don't have any problems with shutdown, reboot, etc. on Gnome. What desktop environment are you using?

    I'm using Gnome as well.

    Like helloworld1 said, it seems to be connected to suspend/hibernate.
    For me, I think it happens after resuming from hibernate.

    In addition to the problems above, I also lose all sound.

    Unlike what I said before, logging out and back in fixes it (no need to reboot).

    Thanks!

    Yes, the pulseaudio permission is also gone. So I have no audio. It is just like I don't have any permissions other than my own user account.
    It happens occasionally after resume from suspension.
    I am using gnome.
    I wonder which component should I file to Bugzilla.

    Hi, I have the same problem after I hibernate/resume. I noticed:

    1. The shutdown, restart buttons don't appear
    2. Logout, hibernate, suspend buttons show up, but don't do anything when you click on them.
    3. Software package updates (which require a root authorization) faill with an error msg saying no credentials.

    Seems like this is a known bug and will likely get fixed. In the mean time are there any workarounds, other than to reboot the system from the command line.

    How do i just logout/login?

    Just verified this workaround fixed the issue:
    CTRL-ALT-F2 followed by
    CTRL-ALT-F1

    (I did login in the console screen the first time I had to use this workaround).
