nVidia release their own Linux drivers which provide good performance and full |
40 |
The nVidia drivers in the tree are released by nVidia and are built against the |
| 41 |
3D acceleration. There are two drivers in Portage. <c>nvidia-drivers</c> is for |
41 |
Linux kernel. They contain a binary blob that does the heavy lifting for talking |
| 42 |
newer nVidia graphics cards, while <c>nvidia-legacy-drivers</c> supports older |
42 |
to the card. The drivers consist of two parts, a kernel module, and an X11 |
| 43 |
cards. |
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 |
use <c>nvidia-legacy-driver</c> if your cards is not supported in the |
| 51 |
<c>nvidia-drivers</c> package. |

The <c>nvidia-legacy-driver</c> branch supports older nVidia cards which are no |
| 75 |
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 |
| 79 |

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 NV3x 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 |
<uri>http://us.download.nvidia.com/XFree86/Linux-x86/1.0-9746/README/appendix-a.html</uri>. |
