13     Many Gentooists have an nVidia chipset on their system. nVidia provides specific
14     Linux drivers to boost the performance of your card. This guide informs you how
15     to install and configure these drivers.

26     <title>Installing the Appropriate Drivers</title>
27     <body>
28    
29     <p>
30     The nVidia drivers include kernel modules that must integrate in your current
31     kernel. To accomplish this, your kernel must support the loading of kernel
32     modules. If you used <c>genkernel</c> to configure the kernel for you then
33     you're all set. If not, double check your kernel configuration so that this
34     support is enabled:
35     </p>
36    
37     <pre caption="Enabling the Loading of Kernel Modules">
38     Loadable module support ---&gt;
39     [*] Enable loadable module support
40     </pre>
41    
42     <p>
43     nVidia's modules and libraries are combined in two packages: <c>nvidia-glx</c>
44     and <c>nvidia-kernel</c>. The former are the X11 GLX libraries while the latter
45     are the kernel modules. You need both so you should install those now.
46     </p>
47    
48     <pre caption="Installing the nVidia modules">
49     # <i>emerge nvidia-glx nvidia-kernel</i>
50     </pre>
51    
52     <p>
53     Once the installation has finished, run <c>modprobe nvidia</c> to load the
54     kernel module into memory.
55     </p>
56    
57     <pre caption="Loading the kernel module">
58     # <i>modprobe nvidia</i>
59     </pre>
60    
61     <p>
62     You probably want to have this done each time you boot your system, so edit
63     <path>/etc/modules.autoload.d/kernel-2.6</path> (or <path>kernel-2.4</path>) and
64     add <c>nvidia</c> to it. Don't forget to run <c>modules-update</c> afterwards!
65     </p>

74     <title>Configuring the X Server</title>
75     <body>
76    
77     <p>
78     Once the appropriate drivers are installed you need to configure your X Server
79     (XFree86 or Xorg) to use the <c>nvidia</c> driver instead of the default
80     <c>nv</c> driver.
81     </p>
82    
83     <p>
84     Open <path>/etc/X11/XF86Config</path> (or <path>/etc/X11/xorg.conf</path>) with
85     your favorite editor (such as <c>nano</c> or <c>vim</c>) and go to the
86     <c>Device</c> section. In that section, change the <c>Driver</c> line:
87     </p>
88    
89     <pre caption="Changing nv to nvidia in the X Server configuration">
90     Section "Device"
91     Identifier "nVidia Inc. GeForce2"
92     <i>Driver "nvidia"</i>
93     VideoRam 65536
94     EndSection
95     </pre>
96    
97     <p>
98     Run <c>opengl-update</c> so that the X Server uses the nVidia GLX libraries:

108     <title>Testing your Card</title>
109     <body>
110    
111     <p>
112     To test your nVidia card, fire up X and run the <c>glxinfo | grep direct</c>
113     command. It should say that direct rendering is activated:
114     </p>
115    
116     <pre caption="Checking the direct rendering status">
117     $ <i>glxinfo | grep direct</i>
118     direct rendering: Yes
119     </pre>
120    
121     <p>
122     To monitor your FPS, run <c>glxgears</c>.
