Description Armands Liepins 2010-02-06 19:39:32 UTC 
Description of problem:
Screen Brightness control in the Power Management applet does not work. 
The slider stays at leftmost position although brightness is at maximum, moving it does nothing. The problem started after some package update. If restart messagebus, brightness control starts to work until the next login.

in the /var/log/messages:

these seems to be related:

Comment 1 Kevin Kofler 2010-02-06 19:56:04 UTC 
I think this is one of the "something creates /tmp/.X11-unix with a wrong SELinux context, preventing pam_console and thus D-Bus's at_console detection from working" bugs, i.e. bug 499183 or bug 550013.
Comment 2 Armands Liepins 2010-02-06 20:48:35 UTC 
Yes, that was it, doing restorecon /tmp/.X11-unix fixed the problem. This fixed bug 562452 too. Now question is why it is creating with wrong context?
Comment 3 Kevin Kofler 2010-02-06 20:55:20 UTC 
Well, do you have freenx-server installed? Or maybe tigervnc-server (the vncserver executable)?
Comment 4 Armands Liepins 2010-02-06 21:04:29 UTC 
(In reply to comment #3)
Yes, I have freenx-server installed, wanted to write comment about this, but you was first.
