Many Gentooists have an nVidia chipset on their system. nVidia provides specific
|
| 23 |
|
|
Linux drivers to boost the performance of your card. This guide informs you how
|
| 24 |
|
|
to install and configure these drivers.

The nVidia drivers in the tree are released by nVidia and are built against the
|
| 41 |
|
|
Linux kernel. They contain a binary blob that does the heavy lifting for talking
|
| 42 |
|
|
to the card. The drivers consist of two parts, a kernel module, and an X11
|
| 43 |
|
|
driver. Both parts are included in a single package. Due to the way nVidia has
|
| 44 |
|
|
been packaging their drivers, you will need to make some choices before you
|
| 45 |
|
|
install the drivers. Currently, there are two driver packages in the tree. The
|
| 46 |
|
|
first, <c>nvidia-drivers</c>, is the latest drivers from nVidia and includes
|
| 47 |
|
|
support for the latest cards. The second, <c>nvidia-legacy-drivers</c>, supports
|
| 48 |
|
|
older cards, from the original TNT through the GeForce 6800. However, this
|
| 49 |
|
|
driver does not support the latest features of the newer cards. You should only
|
| 50 |
nightmorph |
1.37 |
use <c>nvidia-legacy-drivers</c> if your cards is not supported in the
|
| 51 |
diox |
1.36 |
<c>nvidia-drivers</c> package.

Previously, Gentoo provided separate ebuilds for the nVidia kernel module
|
| 56 |
|
|
(<c>nvidia-kernel</c>) and the X11 GLX libraries (<c>nvidia-glx</c>). These
|
| 57 |
|
|
ebuilds have since been removed from the Portage tree in favor of
|
| 58 |
|
|
<c>nvidia-drivers</c> and <c>nvidia-legacy-drivers</c>. If you use
|
| 59 |
|
|
<c>nvidia-kernel</c> and <c>nvidia-glx</c>, then you should migrate to the
|
| 60 |
|
|
newer packages.

The <c>nvidia-legacy-drivers</c> branch supports older nVidia cards which are no
|
| 75 |
diox |
1.36 |
longer supported in the latest driver releases. This branch is based on an older
|
| 76 |
|
|
code base of the nVidia drivers, and supports the latest kernels and X.Org
|
| 77 |
|
|
versions. You should use this driver if you have a TNT, TNT2, GeForce, or
|
| 78 |
|
|
GeForce 2 series card. The driver compatibility information can be found in
|

The <c>nvidia-drivers</c> branch supports the features in newer nVidia cards.
|
| 91 |
|
|
The latest version of these drivers has dropped support for the NV2x based
|
| 92 |
|
|
cards. If you have a GeForce 3 or GeForce 4 series card, you should mask
|
| 93 |
|
|
<c>>=x11-drivers/nvidia-drivers-1.0.9700</c> in your
|
| 94 |
|
|
<path>/etc/portage/package.mask</path> file. This will prevent newer versions of
|
| 95 |
|
|
the driver which are incompatible with your card from being installed. You can
|
| 96 |
|
|
check for driver compatibility for your card at to determine if it is supported
|
| 97 |
|
|
on the newer drivers at
|
| 98 |

As mentioned above, the nVidia kernel driver installs and runs against your
|
| 113 |
|
|
current kernel. It builds as a module, so it makes sense that your kernel must
|
| 114 |
diox |
1.36 |
support the loading of kernel modules. If you used <c>genkernel all</c> to
|
| 115 |
|
|
configure the kernel for you, then you're all set. If not, double check your
|
| 116 |
nightmorph |
1.31 |
kernel configuration so that this support is enabled:

You also need to enable <e>Memory Type Range Register</e> in your kernel:

<p> Also, if you have an AGP graphics card, you can optionally enable
|
| 134 |
|
|
<c>agpgart</c> support to your kernel, either compiled in or as a module. If
|
| 135 |
|
|
you do not use the in-kernel agpgart, then the drivers will use their own
|
| 136 |
|
|
<c>agpgart</c> implementation, called <c>NvAGP</c>. On certain systems, this
|
| 137 |
|
|
performs better than the in-kernel agpgart, and on others, it performs worse.
|
| 138 |
|
|
You will need to evaluate this on your own system to get the best performance.
|
| 139 |
|
|
If you are unsure what to do, use the in-kernel agpgart:

For x86 and AMD64 processors, the in-kernel driver conflicts with the binary
|
| 160 |
|
|
driver provided by nVidia. If you will be compiling your kernel for these CPUs,
|
| 161 |
|
|
you must completely remove support for the in-kernel driver as shown:

To prevent you having to manually load the module on every bootup, you probably

|

want to have this done automatically each time you boot your system, so edit

<path>/etc/modules.autoload.d/kernel-2.6</path> (or <path>kernel-2.4</path>,
|
| 327 |

called "nvidia" which enables XvMCNVIDIA support, useful when watching high

Since nVidia released version 1.0.6106 it also provides you with a settings

<c>media-video/nvidia-settings</c>.

If you are having troubles with the nVidia 2D acceleration it is likely that
|
| 488 |
|
|
you are unable to set up a write-combining range with MTRR. To verify, check
|
| 489 |
|
|
the contents of <path>/proc/mtrr</path>:

swift |

</pre>
|
| 495 |
|
|
|
| 496 |
|
|
<p>
|
| 497 |
|
|
Every line should contain "write-back" or "write-combining". If you see a line
|
| 498 |
|
|
with "uncachable" in it you will need to change a BIOS setting to fix this.
|
| 499 |

|
</p>
|
| 500 |
|
|
|
| 501 |
|
|
<p>
|
| 502 |
|
|
Reboot and enter the BIOS, then find the MTRR settings (probably under "CPU
|
| 503 |
|
|
Settings"). Change the setting from "continuous" to "discrete" and boot back
|
| 504 |
|
|
into Linux. You will now find out that there is no "uncachable" entry anymore
|
| 505 |
|
|
and 2D acceleration now works without any glitches.

This usually occurs when you don't have a matching video card. Make sure that
|
| 518 |
|

you have an nVidia-powered graphical card (you can double-check this using
|
| 519 |
|
|
<c>lspci</c>).

If you are confident that you have an nVidia card, check your BIOS and see if

|
|
the directive <e>Assign IRQ to VGA</e> is set.

The <c>nvidia</c> kernel module accepts a number of parameters (options) which
|
| 558 |
|
|
you can use to tweak the behaviour of the driver. Most of these are mentioned in
|
| 559 |
|
|
the documentation. To add or change the values of these parameters, edit the
|
| 560 |
|
|
file <c>/etc/modules.d/nvidia</c>. Remember to run <c>modules-update</c> after
|
| 561 |
|
|
modifying this file, and bear in mind that you will need to reload the
|
| 562 |
|
|
<c>nvidia</c> module before the new settings take effect.
