Fedora 12 Post-Installation Changes

F12 Post-Installation Changes

Before a Linux distribution such as Fedora 12 is really ready for general use, there are a number of important changes that need to first be made. Some of these, though trivial, provide added measures of security, flexibility, and robustness to the system. Others are simply a matter of personal preference and taste. In light of this, I have tried to break down the changes with respect to their relative "Order of Importance." The steps in this subsection of the Installation Notes should thus be performed in order, because some of the later changes depend upon ones earlier on.

Before any post-installation changes are made, one of the first things I typically like to do is quickly adjust various Gnome settings before proceeding any further (even though I'll soon be using Enlightenment as a replacement for Gnome). These include:

gnome-terminal Preferences

Open a gnome-terminal (Applications -> System Tools -> Terminal), and click on Edit -> Profiles... -> Default -> Edit -> Colors. Deselect the "Use colors from system theme" box, and choose the White on Black option from the drop-down menu. Much better. Hit Close twice.

Desktop Background and Theme

If you want to change the Fedora background click System -> Preferences -> Appearance -> Background. You may have to choose the Fill Screen option from the drop down box, depending upon your resolution.

I do not particularly care for the Clearlooks theme, so click the Theme tab followed by Customize... . Under Window Border, choose Crux. If you want, then click on Icons and make sure Bluecurve or Clearlooks is chosen (although I do not mind the default Fedora icons). Hit Close twice.


The screensaver is an unnecessary drain on resources especially for my server. Click on System -> Preferences -> Look and Feel -> Screensaver. Choose the "Blank Screen" option and unclick the "Lock screen when screensaver is active" box. Hit Close when finished.


I am extremely preferential with respect to windows options. Click on System -> Preferences -> Windows, and make sure the "Select windows when the mouse moves over them" option is set under Window Selection, but the "Raise selected windows after an interval" is not. Under Titlebar Action, choose Roll up from the drop-down box. Hit Close when finished.

Note:  For Fedora 12, this option is not available by default (Gnome developers
you are killing me), so use yum to install the following package first:
~> sudo yum install control-center-extra

Gnome vs. Enlightenment

Part of the reason for not necessarily sticking with Gnome is that development of its old windows manager, Sawfish (which was a thing of beauty), died eons ago and the default windows manager as of Fedora Core 3, Metacity, is next to useless (although, I do have to admit that due to the new CFS Scheduler as of Fedora 9, Gnome seems to finally more responsive and Metacity does not seem to be as annoying as it used to be in days past). Once we get to the Enlightenment section in the HOWTOs, I'll explain further. But for now, this will do.
