System Procedures

Graphics

The following list describes basic troubleshooting tips that you can use to isolate graphics 
problems.

•

Each time X starts a log file is generated in 

/var/log/Xorg.0.log

. Common 

problems that occur after editing the 

xorg.conf

 file can be solved by examining 

this file.

•

Look for visual artifacts on display device:

•

Vertical or horizontal stripes

•

Pixel  drop-outs

•

Missing colors

•

Run graphics demos to verify performance characteristics of the graphics hardware.

•

Run  the 

glxinfo

 command to verify that direct rendering (DRI) is enabled and the 

OpenGL vendor string is set to NVIDIA Corporation; this confirms the graphics 
board is using the NVIDIA driver and not the default RHEL/SLES driver

•

Run  the 

nvidia-bug-report.sh

 script to verify that the NVIDIA driver installed 

correctly

•

If necessary, reinstall the graphics drivers; after reinstalling, run the 

ldconfig

 

command

•

Use  the 

nvidia-xconfig

 command to generate a new 

xorg.conf

 file

•

Swap the graphics card, display device, and display cables to isolate failures

BMC Configuration

The following list describes basic troubleshooting tips that you can use to isolate BMC 
configuration problems.

•

By default, the SGI Virtu VN200 system enables serial-over-LAN (SOL) 
functionality via serial port B. 

•

To configure SOL manually, enable serial-console redirection in BIOS, then 
configure the BMC LAN to assign a static IP address (XE) or configure the BMC as a 
DHCP client (ICE) via one of the following methods:
