Getting Started with Remote Graphics Software

Properly configured kernel headers for the running kernel must be available from the
directory /lib/modules/<version>/build for proper installation. The example
installation script provided only builds/installs for the currently active kernel.
The installation and configuration scripts require administrator privileges on the
target system. If you cannot become root on your system, ask an administrator for
assistance.
Once ALSA and JACK are installed and correctly configured, you are ready to use
remote audio with the RGS Receiver for Linux.
Audio Requirements
For reliable audio support with the Receiver for Linux, the bundled version of the
JACK Audio Connection Kit software must be built and installed. ALSA sound libraries
must be HP-supported or Red Hat Enterprise Linux (release 4 or greater) versions for
best results. Manual installation of prior ALSA libraries may yield unpredictable
results on older releases of Linux. Do not mix versions of ALSA software.
If multiple audio devices are installed in a system, administrators should identify the
target audio system prior to installing the included ALSA software.
Properly configured kernel headers for the running kernel must be available from the
directory /lib/modules/<version>/build for proper installation. The example
installation script provided only builds/installs for the currently active kernel.
The installation and configuration scripts require administrator privileges on the
target system. If you cannot become root on your system, ask an administrator for
assistance.
System Preparation
It is recommended to remove all previously installed versions of JACK before
installation. If the RPM package manager was utilized, then the packages are located
by:
•
rpm -qa | grep -i jack
Removal by RPM involves utilizing the above search results with:
•
rpm -e --nodeps --allmatches {pkg-name}
The install script rgs_audio_support may detect residual directories from previous
installations. Respond as prompted during installation.
Customized Installation
The following remote audio installation for Linux process is used when the RGS
Receiver is installed (through the ./install.sh script). For those installations that
require customization or wish to use other features from the rgs_audio_support
script, here are additional details for its use.
The audio support bundle ships as hp_rgs_4_audiosupport.tar.gz. It is accessed
by the RGS install.sh script in /opt/hpremote or may be utilized for manual
installations / RPM package building.
