Configuration files for SN25P - AMD64

Here is a list of the different main configuration files I am using on my SN25P box.

/etc/make.conf

This file controls the configuration and compilation process while installing new packages with Portage.As such, it is essential.

CFLAGS="-O2 -pipe -march=k8 -fomit-frame-pointer"
CHOST="x86_64-pc-linux-gnu"
CXXFLAGS="${CFLAGS}"
MAKEOPTS="-j2"

# No 3dnow USE flag since AMD64 can use faster sse/sse2 instructions

LINGUAS="en fr ru es"

ALSA_CARDS="ice1724"

INPUT_DEVICES="keyboard mouse"
VIDEO_CARDS="nv nvidia"

/etc/rc.conf

This file contains global startup script configuration settings.

# UNICODE specifies whether you want to have UNICODE support in the console.
# If you set to yes, please make sure to set a UNICODE aware CONSOLEFONT and
# KEYMAP in the /etc/conf.d/consolefont and /etc/conf.d/keymaps config files.

UNICODE="yes"

# Set EDITOR to your preferred editor.
# You may use something other than what is listed here.

EDITOR="/bin/nano"

#EDITOR="/usr/bin/vim"
#EDITOR="/usr/bin/emacs"

# What display manager do you use ?  [ xdm | gdm | kdm | entrance ]
DISPLAYMANAGER="kdm"

# XSESSION is a new variable to control what window manager to start
# default with X if run with xdm, startx or xinit.  The default behavior
# is to look in /etc/X11/Sessions/ and run the script in matching the
# value that XSESSION is set to.  The support scripts are smart enough to
# look in all bin directories if it cant find a match in /etc/X11/Sessions/,
# so setting it to "enlightenment" can also work.  This is basically used
# as a way for the system admin to configure a default system wide WM,
# allthough it will work if the user export XSESSION in his .bash_profile, etc.
# 
# NOTE:  1) this behaviour is overridden when a ~/.xinitrc exists, and startx
#           is called.
#        2) even if ~/.xsession exists, if XSESSION can be resolved, it will
#           be executed rather than ~/.xsession, else KDM breaks ...
#
# Defaults depending on what you install currently include:
#
# Gnome - will start gnome-session
# kde-<version> - will start startkde (look in /etc/X11/Sessions/)
# Xsession - will start a terminal and a few other nice apps

#XSESSION="kde-3.5.2"

/etc/conf.d directory

This directory contains many important configuration files, such as clock, keymaps, net.
