HP-UX Configuration

ATI RADEON 7500 PCI Graphics Controller Installation Guide

Configuring Graphics Resolution or Vertical Refresh Rate for HP-

Use the sam (pre HP-UX 11.31 release) or smh (HP-UX 11.31 and later) program to modify the graphics

resolution or refresh rate.

Current Graphics Resolution

The default graphics resolution and refresh rate are 1280x1024 at 75Hz. The current graphics resolution

and refresh rate of a running system can be obtained by executing the command

/opt/graphics/common/bin/setmon –p.

How to Change the Resolution and Refresh Rate

1. Log in to the system as root.

2. Run /usr/sbin/sam (pre HP-UX 11.31 release) or /usr/sbin/smh (HP-UX 11.31 and later). Choose

Display-> Monitor Configuration. All graphics cards in the system are listed. Choose the graphics device

that is to be updated. From the pull-down menu, choose

Actions->Modify Monitor Type. A new menu

appears that contains all of the possible resolutions and refresh rates. Choose the new setting and press

OK. The selected values will be the new resolution and refresh rate for the Xserver.

NOTE: See Table 4-1 for supported resolutions and refresh rates.

3. Restart the Xserver.

Multihead Support

Multihead support is provided through changes to the Xserver’s configuration file which is located at

/etc/X11/XF86Config. In order to do this correctly, you will need to know which device files to use. See

“Verification of Hardware Installation“ on page 22 for details on how to determine which device files to use.

Multi-screen

By default, an ATI RADEON 7500 appears as a single screen device. You can configure your system so two

or more screens are created. The following example will show you how to configure three screens.

XF86Config Changes

There are three sections in the configuration file you need to change:

1. ServerLayout section. The ServerLayout section contains references to the Screen:

sections.

2. Screen sections. The Screen sections in turn contain references to the Device sections.

3. Device sections.

For this example, we will assume there are two ATI RADEON 7500 graphics controllers in the system.

These graphics cards have the device files /dev/gvid0 and /dev/gvid1. We will change the XF86Config file

to allow for a three-screened multi-head system. In this configuration two screens will come from the first

graphics card (e.g. /dev/gvid0) and the remaining screen will come from the second graphics card (e.g.

/dev/gvid1).

The lowest level is the Device section. This maps a physical device to a device identifier. The three Device

sections for this example are as follows:

1 2 ... 21 22 23 24 25 26 27 28 29
