Some workstation congurations include AMD graphics hardware. HP recommends use of AMD graphics
drivers for best results on Linux systems.
HP also provides recommended versions of AMD graphics drivers with RPM-compatible installers for RHEL
and SLED distributions. These are available from the HP Installer Kit for Linux and workstation driver support
packages on hp.com.
The open source RADEON and RADEONHD drivers can conict with the AMD graphics drivers by claiming the
hardware early in the boot process. The AMD driver installation process usually blacklists conicting drivers
and turns o kernel mode-setting in the initial RAM image.
Administrator customization of the display characteristics and many other aspects of an AMD graphics driver
environment is available through the following command, which starts the Catalyst Control Center:
/usr/bin/amdcccle
Some settings for AMD graphics, including reconguration of the /etc/X11/xorg.conf le, can be accomplished
through the many options provided by the following command:
/usr/bin/aticonfig
Information can be found in these directories after the driver is installed:
/opt/hp/ati
/usr/share/ati
/usr/share/doc/fglrx
If the automatic init script attempts to rebuild the kernel module, the name of the log le is /var/log/fglrx-
build.log.
