README for Nvidia Linux Drivers, as packaged by livna.org.
|
||
|
|
|
||
|
|
1. After Installation
|
||
|
|
---------------------
|
||
|
|
|
||
|
|
You only have to restart X to start using the Nvidia drivers after
|
||
|
|
installation. Either choose "Log Out" from the GNOME/KDE menu, and then
|
||
|
|
press Ctrl-Alt-Backspace at the login prompt, or press Ctrl-Alt-Backspace
|
||
|
|
directly. You should see a white screen with a big Nvidia logo in the middle
|
||
|
|
for about one second.
|
||
|
|
|
||
|
|
To check that hardware acceleration is working, issue the following command
|
||
|
|
in a terminal:
|
||
|
|
|
||
|
|
glxinfo | grep "OpenGL vendor"
|
||
|
|
|
||
|
|
That should print out
|
||
|
|
|
||
|
|
OpenGL vendor string: NVIDIA Corporation
|
||
|
|
|
||
|
|
Also, the command
|
||
|
|
|
||
|
|
glxinfo | grep direct
|
||
|
|
|
||
|
|
should print out
|
||
|
|
|
||
|
|
direct rendering: Yes
|
||
|
|
|
||
|
|
If it does, you're all set.
|
||
|
|
|
||
|
|
2. Basic Configuration
|
||
|
|
----------------------
|
||
|
|
|
||
|
|
The installation scripts perform the basic configuration for you.
|
||
|
|
When (if) you uninstall the drivers, the configuration is reset to
|
||
|
|
use the X.org/XFree86 Nvidia drivers again. If you want to temporarily
|
||
|
|
disable the Nvidia drivers without uninstalling, you can issue the
|
||
|
|
following two commands as root (remember su -):
|
||
|
|
|
||
|
|
nvidia-config-display disable
|
||
|
|
|
||
|
|
To re-enable the Nvidia drivers, run:
|
||
|
|
|
||
|
|
nvidia-config-display enable
|
||
|
|
|
||
|
|
|
||
|
|
3. Additional configuration
|
||
|
|
---------------------------
|
||
|
|
|
||
|
|
It's possible to configure image quality and performance by setting various
|
||
|
|
environment variables. Take a look at /etc/profile.d/nvidia.sh
|
||
|
|
(or .csh if you use csh) and read the README file in the same directory
|
||
|
|
as this file.
|
||
|
|
|
||
|
|
There are a number of settings in the X configuration file as well.
|
||
|
|
The most interesting are acceleration of the XRENDER extension and AGP
|
||
|
|
configuration. In the Driver section of /etc/X11/xorg.conf, you may add
|
||
|
|
the following line:
|
||
|
|
|
||
|
|
Option "RenderAccel" "true"
|
||
|
|
|
||
|
|
to enable XRENDER acceleration. A value of "false" disables it.
|
||
|
|
Note: this has shown to make some systems unstable, making the display freeze.
|
||
|
|
If you experience this, set to "false" or comment out the line.
|
||
|
|
|
||
|
|
To control AGP behaviour, add the following line to the Driver section:
|
||
|
|
|
||
|
|
Option "NvAGP" "X"
|
||
|
|
|
||
|
|
where X is 0, 1, 2 or 3. The different values are as follows (from Nvidia
|
||
|
|
README):
|
||
|
|
|
||
|
|
0 : disable agp
|
||
|
|
1 : use NVIDIA's internal AGP support, if possible
|
||
|
|
2 : use AGPGART, if possible
|
||
|
|
3 : use any agp support (try AGPGART, then NVIDIA's AGP)
|
||
|
|
|
||
|
|
Default is 3. AGPGART is the Linux kernel AGP driver. See Nvidia README,
|
||
|
|
appendix D for more information. AGP speed is controlled by giving a parameter
|
||
|
|
to the Nvidia kernel module, but should be autodetected in most cases.
|
||
|
|
See output of "modinfo nvidia".
|
||
|
|
|
||
|
|
For more configuration options (TwinView, TV-out etc) see the Nvidia README.
|
||
|
|
|
||
|
|
4. An Initscript to enable/disable nvidia driver
|
||
|
|
------------------------------------------------
|
||
|
|
|
||
|
|
To make gdm work at system start this package contains an initscript that
|
||
|
|
will be run during start up. This script will detect if the nvidia module
|
||
|
|
for the running kernel is present. If the module is present, then the
|
||
|
|
initscript will run.
|
||
|
|
|
||
|
|
"nvidia-config-display enable"
|
||
|
|
|
||
|
|
so that the X server will use the nvidia driver, otherwise it will run
|
||
|
|
|
||
|
|
"nvidia-config-display disable"
|
||
|
|
|
||
|
|
and X will use the nv driver. You can disable this check by running, as
|
||
|
|
root (with root $PATH) :
|
||
|
|
|
||
|
|
chkconfig nvidia off
|
||
|
|
|
||
|
|
|
||
|
|
This script will also be invoked when switching to runlevels 6
|
||
|
|
(reboot) and 0 (halt). When rebooting (or shutting down) the system,
|
||
|
|
the script will _disable_ nvidia driver (and switch back to "nv"
|
||
|
|
driver), so that, whatever the kernel you boot, Red Hat Graphical Boot
|
||
|
|
will work.
|
||
|
|
|
||
|
|
We suggest you read the chkconfig(8) man page for complete
|
||
|
|
informations about how to handle rc scripts.
