My Gentoo Installation (Work in Progress)

I've finally decided to really dedicate myself to learning Linux and using Linux more than I currently do. The first step is taking the main computer (my laptop) that I use all the time and converting it from Windows XP to Gentoo.

Laptop Specs

Dell Inspiron 6400

Intel T7400 - Core 2 Duo 2.16Ghz

1GB of RAM

60GB Hard Drive

ATI X1400 Video Card

Conexant HDA D110 MDC V.92 Modem

Broadcom 440x 10/100 Integrated Contoller

Intel PRO/Wireless 3945ABG Network Connection

Standard SD Host contoller (Secure Digital Card)

SigmaTel High Definition Audio Codec

Intel USB2 Enhanced Host Controller

So, I started doing this research to figure out some common things that I'm going to have to know when I do my gentoo installation based on these specs. So far I've determined, thanks to the help of #gentoo on irc.freenode.net that i'll need to use the following for my processor to take full advantage of it. Special Thanks to FunnyMan3595 for his help!

Code:
CHOST="i686-pc-linux-gnu"

CFLAGS="-march=nocona -O2 -pipe -fomit-frame-pointer"

MAKEOPTS="-j3"

CXXFLAGS="${CFLAGS}"

USE Flags = mmxext sse2

It was suggested to use -march=prescott because it 'might' be faster, however Intel recommends -march=nocona. I found that prescott was origionally suggested in a gentoo forums debate for core duo processors. Since then Core 2 Duo has come out and it's recommended nocona. Another note I found was "As of GCC 4.3, you can set -march to "core2". This also enables the SSSE3 instruction set, also new in 4.3. However, gcc 4.3 is only available in the gentoo 'toolchain' overlay and given it's stability level (pre-alpha) you'd be mad to use that right now."

You can continue to watch the Gentoo Safe_Cflags page for updates.

From here I'm going to continue my research on other applications I plan to run and what flags or options I'll need to use to customize my system for the best performance. More to come....

Suggestions from others...

Nastjuid from #gentoo on Efnet told me to check into tmpfs and parallel-fetch on the gentoo-wiki. Here is what I found.

tmpfs - [/url]http://gentoo-wiki.com/TIP_Speeding_up_portage_with_tmpfs

parallel-fetch - When you are emerging a series of packages, Portage can fetch the source files for the next package in the list even while it is compiling another package, thus shortening compile times. To make use of this capability, add "parallel-fetch" to your FEATURES.

<deface> mechtn: i'd also add truetype & xft to your use flags

installed ufed to help me pick my use flags

Also used this website to help me. [/url][url=http://www.gentoo.org/dyn/use-index.xml]http://www.gentoo.org/dyn/use-index.xml

had to make some changes to add xdm into the picture

nano -w /etc/rc.conf

then had to restart xdm

/etc/init.d/xdm restart
