D Linux technical notes HP offers a variety of Linux solutions for HP workstation customers: ● HP supports Ubuntu on some HP workstations. ● HP supports Red Hat Enterprise Linux (RHEL) on HP workstations. ● HP certifies and supports SUSE Linux Enterprise Desktop (SLED) on HP workstations. For Linux setup and restore procedures, see the user guide for your workstation at http://www.hp.com/support/ workstation_manuals.
Audio All HP workstations come with built-in audio hardware. The audio hardware is supported by the Advanced Linux Sound Architecture (ALSA) drivers included with all modern Linux distributions. The audio hardware provides basic playback and recording features. The ability to simultaneously play audio from multiple sources, such as applications and CDs, is provided in the ALSA driver that provides audio mixing. The performance of software audio mixing and playback is greatly improved in ALSA version 1.0.
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.
AMD graphics workstations Some workstation configurations include AMD graphics hardware. The supported Linux distributions should all have some “in-box” driver that supports the hardware well enough for the X server to run. Here are some of the Xorg drivers that may be loaded as the server starts: ● The Radeon in-box X driver will associate with some older GPUs. ● The fbdev or vesa X driver may activate for certain other cards.
