All,

So here's the issue:

The system - a Dell Precision M4800

The OS - CentOS 6.9, ver. 2.6.32-696.28.1

The problem - Whenever the user tries to make system changes (display, mouse orientation, etc.), the gnome-settings-daemon pops up and says it can't run, and the changes never occur. I've looked into the /var/log/messages, and have seen some weirdness from dbus-daemon such as:

dbus-daemon: [system] Rejected send message, 1 matched rules; type="method_call", sender=":1.15" (uid=42 pid=5042 comm="gnome-power-manager) interface="org.freedesktop.Hal.Device.LaptopPanel" member="SetBrightness" error name="(unset)" requested_reply=0 destination=":1.1" (uid=68 pid=2920 comm="hald))

And..

dbus-daemon: [system] Rejected send message, 2 matched rules; type="method_return", sender=":1.1" (uid=0 pid=2912 comm="NetworkManager) interface="(unset)" member="(unset)" error name="(unset)" requested_reply=0 destination=":1.52" (uid=2290 pid=4122 comm="nm-applet))

Any ideas?
