A hostname is a unique name created to identify a machine on a network. In computer networking, a hostname  is a label that is assigned to a device connected to a computer network and that is used to identify the device in various forms of electronic communication such as the World Wide Web, e-mail or Usenet. Hostnames may be simple names consisting of a single word or phrase, or they may be structured.

==Configuration==
|Repository=Funtoo Overlay
In Funtoo Linux <code>/etc/conf.d/hostname</code> is the master configuration file for setting a hostname. In OpenRC framework <code>/etc/conf.d/foo</code> is the configuration file for a corresponding Init script <code>/etc/init.d/foo</code>. With the case of hostname, default value in <code>/etc/conf.d/hostname</code> is set to ''localhost'', means when system boots and OpenRC's <code>/etc/init.d/hostname</code> script started a hostname getting only ''localhost'' name. How it looks?  In your shell promt this will look in following way, an example for root:
|Overlay=Funtoo

== Introduction ==
 
NVidia have proprietary graphics drivers for Linux under binary blob. The alternative open source driver is nouveau.
 
=== Preparing to Install ===
 
==== Hardware compatibility and driver versions ====
 
Currently there are five meta versions of nVidia Linux drivers each of which supports a specific group of GPUs. To check the type of driver that is related to your video card, check the link on this page of the official nVidia:
 
[www.nvidia.com/object/IO_32667.html]
 
If you have identified as your driver version 337.25, for example, you need the mask(s) driver(s) latest(s) to which you want to install.
 
<console>
<console>
###i## echo “>x11-drivers/nvidia-drivers-340” >> /etc/portage/package.mask
localhost ~ # ##i## Hello :)
</console>
</console>
 
Let's play a bit with a configuration. Open <code>/etc/conf.d/hostname</code> with your favorite editor and set a hostname of your choice. Below, I will use a real examples of my working test box.
==== The required kernel options ====
 
{{kernelop|desc=
[*] Enable loadable module support
}}
 
{{kernelop|desc=
[*] MTRR (Memory Type Range Register) support
}}
 
To we made a successful compilation of the legacy nVidia driver, we set before the removal of the native framebuffer drivers into the kernel in order to avoid conflicts for x86 and AMD64 processors, in this case.
 
{{kernelop|desc=
Device Drivers >
  Graphics support >
    <*> Support for frame buffer devices >
      <> nVidia Framebuffer Support
      <> nVidia Riva support
}}
 
{{fancytip| An alternative is to [[uvesafb| uvesafb]] framebuffer, which can be installed in parallel with nvidia-drivers }}
 
==== Installation ====
 
Upgrade and/or configure VIDEO_CARDS variable "nvidia" in /etc/make.conf. This will serve to while you are installing the Server X, the correct version of nvidia-drivers to be provided for you.
 
{{fancynote| Installing to the driver with the option in gtk use flags will make it installed the media-video/nvidia-settings which is a graphical tool for monitoring and various settings for your video card}}
 
==== Emerging the package ====
 
<console>
<console>
###i## emerge x11-drivers/nvidia-drives
localhost ~ # ##i## nano /etc/conf.d/hostname
</console>
</console>
 
Let's set it to hostname="oleg-stable.host.funtoo.org". Save the file and restart  a hostname service:
When the installation is complete run '''modprobe''' nvidia module to read kernel memory.
 
<console>
<console>
###i## lsmod | grep nvidia
localhost ~ # ##i## service hostname restart
</console>
</console>
If an update before remove the old module
Now, let's examine our changes, after a restarting a hostname
<console>
<console>
###i## rmmod nvidia
oleg-stable ~ # ##i## Hello :)
###i## modprobe nvidia
</console>
</console>
 
Notice, that we seeing a shortened hostname here, and not a FQDN (Fully Qualified Domain Name). Don't be frustrated , this is how  default bash promt PS1 set. To get nice promts, please, consult http://www.ibm.com/developerworks/library/l-tip-prompt/ <-- this one should be on Funtoo wiki :)
==== Testing your Video Card ====
 
To test your video card run the glxinfo program, which is part of the mesa-progs package. This will check if direct rendering is enabled.
<console>
$ ##i##glxinfo | grep direct
</console>
 
== Configuring ==
 
==== Loading at boot ====
 
To automate the loading of the module when you boot your system, add '''nvidia''' in /etc/conf.d/modules.
 
==== Integration with X Server ====
 
When your X server is installed, the existing logo /etc/X11/xorg.conf you can run the nvidia-xconfig which will set in xorg.conf to identify the video card among other possible configurations.
 
{{file|name=/etc/X11/xorg.conf|body=
Section "Device"
    Identifier    "nvidia"
    Driver        "nvidia"
    VendorName    "NVIDIA Corporation"
    BoardName      "[Nome] [Modelo]"
EndSection
}}
 
==== Enabling support nVidia ====
Include the use flag in '''nvidia''' /etc/portage/make.conf so due to applications that make use of this advantage may withdraw.
 
==== Enabling OpenGL / OpenCL ====
As a requirement, make sure that the Xorg server is not in use during this change. To enable OpenGL and OpenCL.
 
<console>
###i## eselect opengl set nvidia
###i## eselect opencl set nvidia
</console>

Introduction

A hostname is a unique name created to identify a machine on a network. In computer networking, a hostname is a label that is assigned to a device connected to a computer network and that is used to identify the device in various forms of electronic communication such as the World Wide Web, e-mail or Usenet. Hostnames may be simple names consisting of a single word or phrase, or they may be structured.

Configuration

In Funtoo Linux /etc/conf.d/hostname is the master configuration file for setting a hostname. In OpenRC framework /etc/conf.d/foo is the configuration file for a corresponding Init script /etc/init.d/foo. With the case of hostname, default value in /etc/conf.d/hostname is set to localhost, means when system boots and OpenRC's /etc/init.d/hostname script started a hostname getting only localhost name. How it looks? In your shell promt this will look in following way, an example for root: 

localhost ~ #  Hello :)

Let's play a bit with a configuration. Open /etc/conf.d/hostname with your favorite editor and set a hostname of your choice. Below, I will use a real examples of my working test box. 

localhost ~ #  nano /etc/conf.d/hostname

Let's set it to hostname="oleg-stable.host.funtoo.org". Save the file and restart a hostname service: 

localhost ~ #  service hostname restart

Now, let's examine our changes, after a restarting a hostname 

oleg-stable ~ #  Hello :)

Notice, that we seeing a shortened hostname here, and not a FQDN (Fully Qualified Domain Name). Don't be frustrated , this is how default bash promt PS1 set. To get nice promts, please, consult http://www.ibm.com/developerworks/library/l-tip-prompt/ <-- this one should be on Funtoo wiki :)
