NVIDIA Graphics Configuration
RedHawk Linux Version 5.4 Release Notes 67
Simply stopping and restarting X does not always do the trick. It is best to issue the
command(s):
init 1; init 5
or
reboot
See the X server actions logged in /var/log/Xorg.0.log and Xorg.0.log.old.
Normally, X will respond to errors at start up time by telling you there is a problem and offer to
show you the log, then create a fresh configuration.
A fresh configuration looks very much like the configuration created by the installer.
If you are unable to create a working xorg.conf using the nvidia-xconfig utility, it may
be because the directions were not followed precisely, or problems may have been created by
hand edits after the fact. Take logical steps and verify functionality at the various steps.
Try removing /etc/X11/xorg.conf entirely, reboot to runlevel 3, and run nvidia-
xconfig.
DO NOT BOOT TO RUNLEVEL 1 OR SINGLE USER MODE AND RUN nvidia-
xconfig – THIS WILL CREATE A BAD xorg.conf FILE.
If you have the original xorg.conf created by the installer, but it’s not working, you probably
have the wrong driver defined for the primary video display defined by the BIOS. Try the
following config:
Section “ServerLayout”
Identifier “Default Layout”
Screen 0 “Screen0” 0 0
InputDevice “Keyboard0” “CoreKeyboard”
EndSection
Section “InputDevice”
Identifier “Keyboard0”
Driver “kbd”
EndSection
Section “Device”
Identifier “Videocard0”
Driver “vesa”
EndSection
Section “Screen”
Identifier “Screen0”
Device “Videocard0”
DefaultDepth 24
SubSection “Display”
Viewport 0 0
Depth 24
EndSubSection
