Nvidia® Graphics Workstations - HP Z220 SFF Maintenance And Service Manual

NVIDIA Graphics Workstations
®
Some workstation configurations come with NVIDIA Quadro™ graphics hardware. HP recommends
®
use of NVIDIA proprietary graphics 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
installed in the /opt/hp/nvidia folder.
When installing Linux on a workstation that has an NVIDIA card, administrators should select a VESA-
compatible driver to avoid instability experienced with some open-source versions of the Nouveau and
DRM drivers.
Open source versions of Nouveau drivers and NVIDIA proprietary graphics drivers cannot coexist in
the same runtime environment because they use the same hardware resources. If administrators create
their own Linux environments using NVIDIA proprietary graphics 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 the display characteristics and resolutions of an NVIDIA proprietary graphics driver
environment, execute:
/usr/bin/nvidia-settings
To create and manipulate the /etc/X11/xorg.conf file, execute:
/usr/bin/nvidia-xconfig
