2.Display the contents of /dev/gvid_info by executing the following command: cat /dev/gvid_info

The following output should appear. There should be one line (i.e. one device file) for every graphics device in the systems bus:

/dev/gvid0

/dev/gvid1

3.Determine the association of physical graphics cards to special device files (/dev/gvid?) by running the command:

/opt/graphics/common/bin/setmon -N /dev/gvid0

If the device is the HP PCI AMD Radeon 7000 Graphics Adapter card, the output should look like:

Device /dev/gvid0 is a ATI Radeon 7000 Graphics Adapter

You will also see this output for various integrated and manageability card displays.

HP PCI AMD Radeon 7000 Graphics Adapter as Default Xserver Device

The program utility sam (pre HP-UX 11.31 release) or smh can be used to make the HP PCI AMD Radeon 7000 Graphics Adapter the default Xserver device. This is for a single-screen Xserver configuration. For a multihead Xserver configuration, see “Multihead Support” (page 25).

1.Login as root.

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

Select Display->Xserver Configuration. All graphics cards in the system are listed. Select the graphics device that is the current Xserver device. This device may or may not be the HP PCI AMD Radeon 7000 Graphics Adapter. From the pull down menu, select

Actions->Remove Screen from Configuration. Select the new device you would like to be the default Xserver device. The new device should be one of the HP PCI AMD Radeon 7000 Graphics Adapter device entries. From the pull down menu, select Actions->Add Screen to Configuration.

3.Restart the Xserver.

The HP PCI AMD Radeon 7000 Graphics Adapter supports multiple monitor resolutions and refresh rates. Those elements are determined by the monitor which is connected to the graphics adapter. Note the supported resolutions must fall within the limitations of the graphics adapter and HP-UX driver.

The AH391A graphics adapter and HP-UX driver have the following limitations:

•Resolutions less than 1024x768 are not supported.

•Resolutions using the DVI digital cable are limited to a maximum of 1600x1200 @ 60Hz on a 4:3 aspect ratio or a maximum of 1680x1050 @ 60Hz on a widescreen monitor.

•Resolutions using the VGA analog cable are limited to a maximum of 1920x1200 @ 60Hz.

•The following table shows examples of supported resolutions:
