yum install gnome-tweak-tool -y
The settings I use in it:
I manually and automatically update my software and I do not want any
background process holding the yum lock. To disable PackageKit checking for
software open the application "Software Settings" or
Change "Check for updates" to Never, Automatically install "Nothing, and "Check for major upgrades" to Never.
Man this bothered me for so long, inside a user's terminal session execute this command to prevent applications from stealing focus:
gconftool-2 -s -t string /apps/metacity/general/focus_new_windows "strict"
