Before Installation

Refer to your system platform documentation for proper procedures on how to shut down the system safely before installing or removing any internal boards, and how to reboot the system after installation. Access documentation at:

http://www.sun.com/documentation

System Configuration

The Sun XVR-2500 graphics accelerator consumes 75 watts of system power and occupies one PCI-Express slot.

You can configure the Sun Ultra 45 workstation with a maximum of two
Sun XVR-2500 graphics accelerators.

Installing the Hardware

Refer to the platform documentation provided with your Sun system for detailed instructions on installing Sun PCI-Express bus graphics boards:

Sun Ultra 45 Workstation Service and Diagnostics Manual (819-1892-10)

Access system hardware documentation at:

After installing your graphics accelerator and securing your system enclosure:

1. Connect the monitor cable (see Monitor Cables), power on the monitor, then power on the system and reboot (boot) for reconfiguration.

2. For multiple graphics boards, modify the /etc/dt/config/Xservers file.

This file tells your system to run the X window system on each of the graphics boards listed in your Xservers file. If you remove graphics boards from your system, you also need to modify your Xservers file. See Chapter 4, "Configuring Multiple Frame Buffers."

Monitor Cables

Use the proper DVI-I monitor adapter cable that supports your monitor. The DVI-I to HD15 monitor adapter, Sun part number 530-3305, comes with the Sun graphics accelerator installation kit. You can also order the DVI-I to HD15 adapter through the Sun store (http://store.sun.com).

Changing the Monitor Screen Resolutions

Note - The monitor must be connected to the Sun XVR-2500 graphics accelerator and powered on for it to configure to the monitor resolution.

For most installations, the graphics accelerator device automatically configures itself to the screen resolution and refresh rate for the monitor. If a Sun monitor is connected to the graphics accelerator device, the monitor might have the wrong screen resolution. Use the fbconfig utility to change the screen resolution. (To change screen resolutions using the Display Configuration Management tool, DCMtool, see Appendix D.)

SUNWkfb_config contains Sun XVR-2500 graphics accelerator device-specific configuration information.

To change the screen resolution using the SUNWkfb_config man page, type:

% man SUNWkfb_config
