NVIDIA graphics workstations Some workstation configurations come with NVIDIA Quadro graphics hardware. HP recommends the use of NVIDIA drivers for best results on Linux systems. HP provides recommended versions of the drivers with RPM-compatible installers for RHEL and SLED distributions. These are available from the HP Installer Kit for Linux and from workstation driver repositories on hp.com. When HP installers are used, their contents and documentation links are located in the /opt/hp/ nvidia folder. When installing Linux on a workstation that contains an NVIDIA card, administrators should select a VESAcompatible driver to avoid the instability that is experienced with some open-source versions of the Nouveau and DRM drivers. Open-source versions of Nouveau drivers and NVIDIA drivers cannot coexist in the same runtime environment because they use the same hardware resources. If administrators create their own Linux environments using NVIDIA drivers but choose not to use HP-packaged versions, HP recommends that they manually append the following boot loader parameters to properly suppress the Nouveau driver at runtime (grub example below): kernel /vmlinuz ... rdblacklist=nouveau nouveau.modeset=0 This action is applied by HP installers but must be applied/restored under other circumstances. To customize display characteristics and resolutions when the computer is using an NVIDIA driver, execute the following command: /usr/bin/nvidia-settings To create and manipulate the /etc/X11/xorg.conf file, execute: /usr/bin/nvidia-xconfig 102 Appendix D Linux technical notes

NVIDIA graphics workstations
Some workstation
configurations
come with NVIDIA Quadro graphics hardware. HP recommends the use of
NVIDIA drivers for best results on Linux systems.
HP provides recommended versions of the drivers with RPM-compatible installers for RHEL and SLED
distributions. These are available from the HP Installer Kit for Linux and from workstation driver repositories
on hp.com. When HP installers are used, their contents and documentation links are located in the /opt/hp/
nvidia folder.
When installing Linux on a workstation that contains an NVIDIA card, administrators should select a VESA-
compatible driver to avoid the instability that is experienced with some open-source versions of the Nouveau
and DRM drivers.
Open-source versions of Nouveau drivers and NVIDIA drivers cannot coexist in the same runtime environment
because they use the same hardware resources. If administrators create their own Linux environments using
NVIDIA drivers but choose not to use HP-packaged versions, HP recommends that they manually append the
following boot loader parameters to properly suppress the Nouveau driver at runtime (grub example below):
kernel /vmlinuz ... rdblacklist=nouveau nouveau.modeset=0
This action is applied by HP installers but must be applied/restored under other circumstances.
To customize display characteristics and resolutions when the computer is using an NVIDIA driver, execute the
following command:
/usr/bin/nvidia-settings
To create and manipulate the /etc/X11/xorg.conf
file,
execute:
/usr/bin/nvidia-xconfig
