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

• By default, the SGI Virtu VN200 system enables serial-over-LAN (SOL)

• 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:
