Getting Started with Remote Graphics Software
41
1. nVidia method: nVidia graphics drivers have extensions that enable remote
viewing of OpenGL applications using a Remote Graphics Software. This
method requires no user configuration other than making sure the proper
nVidia drivers (version 1.0-5336 and beyond) are properly installed on the
system.
2. LD_PRELOAD method: The LD_PRELOAD method is used for systems that do
not have nVidia graphics installed. Set the LD_PRELOAD environment variable
as follows:
$ export LD_PRELOAD=/opt/hpremote/lib/librgopengl.so
Once the LD_PRELOAD variable is properly set, any OpenGL application can be
started. The application should then properly display in a Remote Graphics
Software environment. To automate the setting of the environment variable,
the variable can be set in the users .profile. For example, for those using bash,
add the following to the system or users .bash_profile:
$ export LD_PRELOAD=/opt/hpremote/lib/librgopengl.so
Adding this to the .profile will enable remote viewing of 3D OpenGL
screensavers.
Enabling OpenGL, PHIGS, PEX and Starbase
Applications on HP-UX
OpenGL, PHIGS, PEX, and Starbase applications are automatically setup for remote
access within an HP Remote Graphics Software environment. No extra setup steps
are necessary. All that is required is that the proper X server and OpenGL libraries to
be installed on the system.
