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.

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:

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. Since <c>nvidia-glx</c> depends on <c>nvidia-kernel</c>,
46 installing <c>nvidia-glx</c> is sufficient:
47 </p>
48
49 <pre caption="Installing the nVidia modules">
50 # <i>emerge nvidia-glx</i>
51 </pre>
52
53 <p>
54 Once the installation has finished, run <c>modprobe nvidia</c> to load the
55 kernel module into memory.
56 </p>
57
58 <pre caption="Loading the kernel module">
59 # <i>modprobe nvidia</i>
60 </pre>
61
62 <p>
63 You probably want to have this done each time you boot your system, so edit
64 <path>/etc/modules.autoload.d/kernel-2.6</path> (or <path>kernel-2.4</path>) and
65 add <c>nvidia</c> to it. Don't forget to run <c>modules-update</c> afterwards!

75 <title>Configuring the X Server</title>
76 <body>
77
78 <p>
79 Once the appropriate drivers are installed you need to configure your X Server
80 (XFree86 or Xorg) to use the <c>nvidia</c> driver instead of the default
81 <c>nv</c> driver.
82 </p>
83
84 <p>
85 Open <path>/etc/X11/XF86Config</path> (or <path>/etc/X11/xorg.conf</path>) with
86 your favorite editor (such as <c>nano</c> or <c>vim</c>) and go to the
87 <c>Device</c> section. In that section, change the <c>Driver</c> line:

96 </pre>
97
98 <p>
99 Run <c>opengl-update</c> so that the X Server uses the nVidia GLX libraries:

112 <p>
113 To test your nVidia card, fire up X and run the <c>glxinfo | grep direct</c>
114 command. It should say that direct rendering is activated:

116
117 <pre caption="Checking the direct rendering status">
118 $ <i>glxinfo | grep direct</i>
119 direct rendering: Yes

123 To monitor your FPS, run <c>glxgears</c>.
