Gentoo Linux is a meta-distribution operating system which provides options and tools for proper customization of Linux. Gentoo Linux can safely edit the /etc/make.conf file in the system without hampering the processes and other system performances and activities.
how to start with the basic modification of GUI :

CHOST=”x86_64-pc-linux-gnu”

This command will show if your operating system and the hardware are compatible to handle the modifications of the operating systems without any problems. The presets and the options for modification of Gentoo Linux work best with stage3 tarball architecture. The CHOST shouldn’t be changed in any computer, but in case of 64 bit architecture, we can use a different code to create the modification of Linux.

This code is used on the 64-bit machine,
CFLAGS=”-march=native -O2 -pipe”
CXXFLAGS=”${CFLAGS}”

And the code for 32-bit machine, we can use,
CFLAGS=”-march=native -O2 -pipe -fomit-frame-pointer”
CXXFLAGS=”${CFLAGS}”

When using this code, make sure that you have that –march must be set to native while, using this code. If not set, the configuration and the modification tools will utilize every resource that is available.

By setting the values for working of hardware peripherals you can also modify the performance of your PC. For getting the maximum performance from CPU when using Linux, you will need to use following code,
MAKEOPTS=”-j3″

This will also enhance the performance of the RAM in the system. Here , j3 denotes that you want 3 cores of the processor to dedicate their power for processes in Linux. Depending on the working of your system, you will also need to reduce the performance of the peripherals. You can also increase the speed by which the system accesses the cache memory by using following command,
FEATURES=”ccache”

For language settings, you can us following command,
LINGUAS=”en_US en”
